Dry Yeast and Hydrogen Peroxide Acid Base Catalysis

Dry Yeast and Hydrogen Peroxide Acid Base Catalysis Mateo Rodriguez Abstract   Category: Chemistry The purpose of this experiment was to figure out if either acids or bases accelerate or decelerate the chemical reaction consisting of dry yeast and hydrogen peroxide. I am trying to prove that the more acidic or the more basic the reaction is, the more accelerated the reaction will be. Enzymes are very important to the human body because they speed up chemical reactions without being a part of it. Enzymes are made up of proteins which are important biological compounds in the formation of living organisms. The addition of an acid or base to yeast makes  a certain amount of bubbles to show how acidity or basicness affects the chemical composition  taking place in the reaction with the yeast. Without the addition of an acid or a base, the reaction is harmless to our bodies. The enzyme Catalase is used in everyday life as well. The protein found in the enzyme is easily changeable with the addition of another substance Among the materials that you need to conduct this experiment are five clear containers, a washable spoon, distilled water, a measuring cup, baking soda, lemon juice, and a set of measuring spoons. The six planned concoctions are control with no acids or bases, low-acid with one teaspoon oflemonjuice, high-acid with two teaspoons of lemon juice, low-base with one teaspoon of baking soda, and high-acid with two teaspoons of baking soda. You might even want to try a combination of both the acid and the base. Next, you must add a Y4 cup of hydrogen  peroxide into the glass. Then add a 1teaspoon of dry yeast and the reaction will begin. Record  your results carefully to track this marvelous experiment. In the end, the reactions that were further away from a neutral pH performed in a more decelerated rate. Therefore, the control, low-acid, and low-base reactions performed at a more accelerated rate than the high-acid and the high-base reactions. However, the combination reaction performed at an exponentially better rate than all other reactions. Although all the mixtures performed within the same range (besides the combination), it was simply due to the reactions being at a microcosmic scale. The experiment ended up proving my initial hypothesis completely incorrect. It would probably be a wise idea to use larger amounts in order to get more appreciable results. The bubbles formed because different atoms in the hydrogen peroxide and the dry yeast collided and then bounced away to be farther away than they were in the beginning. This microscopic change appears to us humans in the form ofbubbles. The enzyme Catalase found in dry yeast, is also found in our bodies organs; primarily the liver. What Catalase does in the liver is manage the graying of our hair. The more Catalase the faster our hair will gray, and the less Catalase there is the slower our hair will gray. Since Catalase is found in our crucial organs, doctors and scientists have done experiments to try and manipulate the enzyme. Their experiments primarily consist of the yeast acting against acids and bases as I did in my project. If this experiment were to be done on a more grand scale, it would sure affect and aid us in our everyday lives. Introduction The purpose of this project is to figure out if either acids or bases accelerate or decelerate the chemical reaction consisting of dry yeast and hydrogen peroxide. Enzymes are very  important to the human body because they speed up chemical reactions without being a part of it. This catalysis isnt just found in the human body, its also in most living things on Earth. Enzymes are made up of proteins which are important biological compounds in the formation of living organisms. The addition of an acid or base to yeast makes a certain amount of bubbles to show how acidity or basicness affects the chemical composition taking place in the reaction with the yeast. If you have ever mixed baking soda and lemon juice in an attempt to fight indigestion, you will see a basic chemical reaction between the two. Without the addition of acids or bases, the yeast reaction is quite harmless to our bodies. However, since we consume acids and bases almost every day, its a great idea to enlighten your self on just how our bodies are working. The main goal of this experiment is to fmd out how well the catalase in yeast breaks down acids and bases or vice versa. Hypothesis  and  Background  Research Acids and basses are two very common terms in many scientific fields, such as chemistry. Acids are chemical substances that dissolve some types of metal and turn litmus intro a red color because of them being of a pH lower than seven. They are typically a corrosive or sour-tasting kind of liquid. Bases on the other hand, are usually of a pH higher than seven and are the opposite of acidic substances. They accept hydrogen ions instead of releasing them such as acids do. Bases will also typically turn litmus paper into a sort of blue color. There are several different types of chemical reactions and changes happening around us in our everyday lives. The most common of these reactions occurs when a raw egg turns solid. This happens because an impressive amount of heat is applied to the raw egg which forms longer and stronger chains of protein molecules inside the egg. This reaction and several others that occur in our body rely on enzymes, which are basically special types of catalysts made up of protein. Catalysts are anything that speeds up an action without being used up themselves. Thus, an acid- base catalysis is the acceleration   of a chemical reaction by the addition of an acid or a base with the acid or base itself not being consumed in the reaction. Enzymes are not only found in human bodies, they are found in all types of living things including yeast. Yeast contains the enzyme known as catalase which breaks down the chemical hydrogen peroxide (H202) into  oxygen gas and water. This would be the react ion that will inform us about the amount of  bubbles formed from the acids and bases. This reaction will also show us how much the yeast has to work to break down the hydrogen peroxide when different substances are also added onto the concoction. Proteins can be changed when a specific amount of heat is brought upon it. Since enzymes are made up of proteins, they too can be changed by heat. However, what a majority of people do not know, is that the addition of acids and bases can also affect the way that a protein is put together. Both acid-catalysis and base-catalyzed reactions are used for their own unique purposes. A macrocosmic example of acid catalysis is the reaction and conversion of the hydrocarbon atoms found in petroleum to gasoline, and the creation of silicone. An example of a grand base ­ catalyzed reaction is the creation and conversion of several compounds and molecules used in the creation of foam sponges. The main reasoning behind this investigation is to discover how well the catalase enzyme in yeast can break down hydrogen peroxide after different amounts of acids and bases have been added onto it. For this experiment, my hypothesis is that the more acidic or the more basic the concoction made in the different cups is, the more bubbles will be made and the higher they will get. Procedure Materials The materials you will need for this experiment include: 5 clear glass containers of equal size (beakers or test tubes are ideal) Permanent marker Tape 5 clean spoons Distilled water Small clear cup/glass Baking soda Set of measuring teaspoons Measuring cup Hydrogen peroxide Dry yeast Ruler Lemon juice Variables         Ã‚   1. The rlcpcndent-ormanipulated variable in this experiment is the amount of lemon juice or baking soda poured into the different containers and thus, the acidity or basicity in each container. 2. The iodepor responding variable in this experiment is the height and amount of bubbles formed as a result of the chemical reaction. 3.   The controlled variable or the variable held constant in this experiment is the amount of yeast and the amount of hydrogen peroxide put in each container and the containers themselves. StepbyStep Directions 1. Label the containers: 1- Control, 2- Low Acid, 3- High Acid, 4- Low Base, and 5-High Base. 2. Put a spoon in each of the containers, and make sure to never move a spoon from one container to the other. 3. Add two teaspoons of distilled water to container 1- Control. 4. Stir in 1 4 cup of hydrogen peroxide to container 1-Control. 5. Stir in 1 teaspoon of yeast to container 1- Control. 6. Place the ruler alongside the container, and record the highest height the bubbles reach 7.Of the other containers, record predictions first, and actual results after on a chart. 8.   To create the acidic containers, add one teaspoon oflemonjuice to container 2- Low Acid and two teaspoons oflemonjuice to container 3-High Acid. 9. Add one teaspoon of distilled water to container 2- Low Acid so it is the same volume as con iner 3. 1O.Stir in V4 cup of hydrogen peroxide to containers 2 and 3. ll.Add 1 teaspoon yeast to both container 2 and 3. Stir and observe. 12.Record the maximum height ofthe yeast bubbles. 13.To create the basic containers, add one teaspoon ofthe baking soda solution to container 4- Low Base and two teaspoons of the baking soda solution to container 5- High Base. 14.Add one teaspoon of distilled water to container 4- Low Base so it has the same volume as container 5. 15.Stir in V4 cup ofhydrogen peroxide to containers 4 and 5. 16.Add 1 8 teaspoon of yeast to both container 4 and 5. Stir and observe 17.Record the maximum height ofthe yeast bubbles. (Compare your predictions with your actual observations) Results There were a plethora of things to be discovered from this otherwise simple experiment. The very flrst thing that you have to be aware of to do this experiment is that there will always be a change to an altered chemical reaction, no matter how small the alteration or the result. The result of each and every chemical reaction wasnt very different, but it was enough so that each showed a noticeable change. The temperature for each experiment I conducted stayed at approximately the same level throughout. The original height of the mixture was approximately 1 inch before adding the yeast. I performed three separate trials for each chemical reaction. The results were approximately the same for every trial I conducted of the different concoctions. The initial height of all the concoctions prior to adding yeast was approximately I inch. The constant reaction worked at the most accelerated rate, thus causing more bubbles to form on the mixtures surface. This occurred because of the fact that the enzyme Catalase works best at around pH 7, and this mixture was very near to the neutral pH. The foamy bubbles made the height of the concoction reach approximately 1.5 inches in an average whiskey glass. The bubbles reached their maximum height at a slow rate. This was true for a majority of the reactions. Control Reaction   Ã‚   The acidic reactions reacted in a very similar way to each other. The low-acid reaction acted in a very similar way to the control reaction in every single trial I conducted. The bubbles in this reaction reached a slightly lower height than that of the control reaction; approximately 1.2 inches. The pH of this composition was slightly more acidic; about a 6 or 5 on the pH scale. The pH being lower is what caused the bubbles to perform in a more decelerated rate. The high-acid reaction also performed at a lesser magnitude than the control reaction. The height of the bubbles reached a height of slightly more than 1 inch. Due to the fact that the high-acid reaction had a lower pH and strayed further from the desired neutral status, it performed the worst of all the reactions thus far. However, this reaction reached its maximum height in a shorter amount of time. Low-Acid  Reaction  High-AcidReaction The low-base mixture reacted in approximately the same way as the low-acid mixture. This is because the two mixtures were the same amount of pH away from the desired neutral pH. This concoction was at a pH of roughly 9 or 10. The height ofthis mixture was approximately 1.2 inches. Even though the amount of acid or base added to the mixture was the same, the one teaspoon of baking soda raised the pH more than the one teaspoon of lemon juice lowered the pH because the baking soda is a powder. It being a powder allows for the individual molecules of the substance to spread around the mixture more than the tangy lemon juice could. The high-base mixture reacted in a very similar way to the high-acid mixture. Again, this was because they  were the same amount away from a neutral pH. The pH of the high-base concoction was a pH of approximately 11 or 12. The maximum height of this mixture reached slightly more than 1 inch. This blend also reached its maximum height in a shorter amount of time than the others. Low-Base  Reaction  High-Base  Reaction Due to the fact that the different reactions reacted in quite a similar way to one another, I decided to conduct an additional experiment. This one consisted of one teaspoon of lemon juice and one teaspoon of baking soda in the beginning. This was to discover if a mixture of the two would accelerate or decelerate the Catalase reaction. I had previous knowledge that a mixture of baking soda and lemon juice resulted in a foamy liquid that helped with indigestion and to fight off minor cancer cells, so I put it to the test with the catalytic enzyme. This concoction reacted in a way like no other. The maximum height of the reaction was approximately 5 inches. This reaction also reached its maximum height quicker than any other reaction. The initial foam of the mixture of the acid and the base caused the yeast bubbles to be larger and whiter in color in comparison to the other reactions. Estimated  Height  of  Yeast  Bubbles Actual  Height  of  Yeast  Bubbles Control 2in. 1.5 in. Low-Acid 3 in. 1.3 in. High-Acid 4in. 1.1in. Low-Base 3.3 in. 1.35 in. High-Base 4.4in. 1.15 in. Combination 5 in. 2.5 in. Conclusion The results proved my hypothesis completely incorrect. I believed that the further away from neutral the concoctions got, the more accelerated the reaction would be. However, the complete opposite to what I believed turned out to be true. I was very surprised to see that every  planned reaction gave approximately the same results. That was why I decided to conduct an  experiment with usually counteracting substances; the acid and the ba::}if I were to do this  experiment again, I would use larger amounts in order to get larger and more visible results. The most plausible explanation of the yeast reaction is that the bubbles formed because the hydrogen and oxide atoms collided with the Catalase in the yeast and then bounced away. Due to the fact that the molecules bounced apart, a larger microscopic gap formed between the atoms. The way us humans see this minuscule separation is in the form of the Catalase bubbles. The way that this reaction could help us in our everyday lives i s actually quite simple. Catalase is found in a majority of human bodies; especially in the liver. What Catalase does in the human body is that  if there is more of it in the liver, your hair will gray at a slower rate or not at all, and if there is not a lot of Catalase in your liver, then your hair will grow at an exponential rate. Due to the fact that Catalase is found in one of our crucial organs, doctors and scientists have conducted  experiments to try and manipulate the enzyme in order to treat ailments in that region of the bodese experiments were simply on a microcosmic scale, which did not allow them to  perform in such a notable and appreciable way. However, on a larger scale, this type of catalysis would be truly helpful in our everyday needs. Bibliography Gray, Theodore.

Sunset Boulevard

Yes, Norma Is That Crazy Sunset Boulevard constantly and persistently advances the theme that Hollywood creates movie stars that become engrossed with their own fame and then abandons them, leaving behind only their outlandish and outdated fantasies. The case of Norma Desmond is no different. Her out-of-touch relationship with reality is given form through her desire to make her â€Å"greatest picture yet. † The segment of Sunset Boulevard that will be analyzed in this essay is significant because, through the use and interplay of cinematography, editing, elements of Mise-en-Scene, and the dialogue, Norma’s delusions are highlighted and magnified.The first few moments of part one of the segment use specific elements of Mise-en-Scene and the dialogue to begin the reinforcement of Norma’s delusions. As her lavish and fanciful car pulls up to the studio door, Norma asks Joe if he would like to accompany her into the studio to meet with Cecil B. DeMille, but Joe refu ses. Joe is dressed fairly normally whereas Norma is wearing a fancy coat and hat to match her equally fancy car. This use of the costumes and makeup suggest that Norma is somehow out of place or out of time because her clothes do not match the occasion.When Joe declines to join Norma in the studio, he explicitly states, â€Å"It’s your script, it’s your show. † This part of the dialogue seems to suggest a separation between Norma and Joe. Norma is excited to meet with DeMille and discuss her movie whereas Joe is content to wait outside with Max and the car – Norma is alone. The next few moments of part one also contain some key lines of dialogue that seem to emphasize the anachronism of Norma Desmond and her fantasies. As she is hugged and greeted by DeMille, she recalls the last time the two had been together.She describes the time as â€Å"very gay,† suggesting that it is a very happy memory. She also remembers waving to DeMille and dancing on a table. It would seem that Norma still associates her relationship with DeMille, and consequently her career as a movie star, with fantastic memories of the past. DeMille mentions that many other people were dancing on tables as well, since Charles Lindbergh had just landed in Paris. This seems to suggest that Norma’s experience (and consequently, her past) is not s special and unique as she would like to believe, but Norma seems ignorant to this subtle suggestion because she is still engrossed by that memory. In the next section of part one, the dialogue between and the behavior of Norma and DeMille heightens the disparity of understanding between the two Hollywood greats. Norma behaves like classic Norma – pretentious with an inflated sense of self-importance. DeMille seems to be walking a line between careful respect and impatience.When Norma asks if he has read her script, DeMille waits for her to break eye contact before looking down and admitting in a rather exas perated and annoyed tone, â€Å"Yes, I did. † DeMille’s facial expression as he says this is key to understanding the distance between him and Norma. He is somewhere between anger, impatience, and confusion, whereas Norma is looking off-screen, seeming quite pleased with herself. DeMille leaves Norma in his director’s chair as he tells one of his assistants to get him on the phone with Gordon Cole, whose calls lead to Norma’s arrival at the studio.The difference between DeMille’s and Norma’s facial expressions and tone reinforce the idea that Norma is living in a fantasy and is separated from reality. The next section of part one uses costumes, lighting, and specific shot angles to reinforce Norma’s delusions about her current importance. A high angle shot of Norma in DeMille’s director’s chair is combined with the use of a spotlight to further Norma’s fantasies about her current importance. When the lighting man puts the spotlight on Norma and exclaims that it’s Norma Desmond for everyone in the studio to hear, the people in the studio surround Norma.Most are dressed for the picture that is being made by DeMille, but there are also a few policemen and normal people as well. The crowd around Norma that is showering her with affection is almost entirely comprised of people in strange clothes. This would seem to suggest that Norma’s sense of self-importance isn’t based in reality. Rather, it is a product of the fantasy world she lives in. In the final moments of part one, non-diegetic music is combined with the dialogue to show that Norma has no idea why she was being called by Gordon Cole.While DeMille is on the telephone with Cole, non-diegetic music is used to heighten the tension and suggest that a revelation is about to be made about the true purpose of the calls to Norma. When Gordon reveals that he was only interested in renting Norma’s luxurious car for a pi cture that is being made, a sudden burst of non-diegetic music is inserted. This music accentuates the difference between Norma Desmond’s reality and actual reality. DeMille pops the fantasy bubble Norma is in by breaking up the crowd of her fans around her and getting the spotlight taken off her.Norma’s fantasy is contrasted with DeMille’s reality when he tries to explain the mix up. She begins weeping out of gratitude for her fans whereas DeMille is trying to let her down as easily as possible. He highlights how detached Norma is when he says that pictures have changed quite a bit since she had been a star. The first half of part two uses cinematography to contrast the Norma’s past and the present. As Max tells Joe about Norma’s old dressing rooms, the camera remains on the car. Joe doesn’t look up at the offices. He doesn’t even seem all that interested in Max’s story.Only when Joe notices Betty does the shot cut away from t he car. Max is still talking but Joe is much more interested in Betty. This use of shot control seems to suggest that Norma and Max’s past is irrelevant to Joe – all he cares about is Betty. The second half of part two uses dialogue to reveal to Max the true nature of the Paramount visit, which shows just how deluded Norma is. Two studio workers walk up to the car as Max is waiting for Joe and Norma to return and ask if they can take a look at the â€Å"funny old car Gordon Cole was talking about. † Max defensively asks what is so funny about the car.He cannot seem to notice how very out-of-place and out-of-time the car is, just as Norma is. The first section of part three uses lighting to contrast with part one. In part one, the inside of the studio is very dark, whereas part three is lighted very well. Betty’s office is well-lit through the open windows and doors, which seems to suggest an air of new life and positivity. DeMille’s studio is quite dark while Norma is present. This contrast seems to highlight the difference between reality and fantasy. Joe and Betty are living in reality – their lives are healthy and growing towards the future, hereas Norma is still living in her past fantasy. Throughout part three, the cinematography and editing, the choice between reality with Betty and fantasy with Norma for Joe is highlighted. Whenever there is a significant portion of Betty’s window visible in the shot, Norma’s car is also visible through the window. As Betty and Joe discuss how to fix up Betty’s script, we can still see the studio workers walking around the car, examining it. Part three also makes significant use of diegetic sound and dialogue to contrast fantasy with reality.As Betty asks Joe to meet with her to work on the script, a car horn begins to honk, calling Joe back to Norma’s fantasy world. Joe takes heed and tries to wrap up the meeting with Betty as soon as possible. Betty , however, is quite insistent and pesters Joe to meet with her. The longer she keeps Joe waiting, the longer and louder the car horn honking becomes. This seems to suggest that Norma’s fantasy world is calling Joe back, keeping him from fully engaging with the present reality. Part four mostly uses non-diegetic sound and music to finish the contrast between reality and Norma’s fantasy.After Max explains to Joe the true reason for the Paramount calls, the camera immediately cuts to Norma and DeMille exiting the studio through the same door they entered earlier in the segment. As Norma insists she isn’t worried about anything and DeMille tries to ship her off without indicating his knowledge of the situation, dark and mysterious music plays. Everyone knows except Norma – not that she cares. Norma is stuck in her fantasy world, convinced that it will become reality. She never picks up on the subtle clues that DeMille gives throughout their interaction that h e has no intention of making a movie with her again.Sunset Boulevard’s theme that Hollywood creates movie stars that become engrossed with their own fame and then abandons them, leaving behind only their outlandish and outdated fantasies, is excellently exemplified through Norma Desmond. Her out-of-touch relationship with reality is given form through her desire to make her â€Å"greatest picture yet. † This segment of Sunset Boulevard is significant because, through the use and interplay of cinematography, editing, elements of Mise-en-Scene, and the dialogue, Norma’s delusions are highlighted and magnified.

A Year Down Yonder

A year Down Yonder is about a girl named Mary Alice who goes to live with her Grandma in a small town with only her cat Bootsie and her potable radio that she says is her last touch with the world. This chapter is called Rich Chicago Girl. Mary Alice gets off a train from Chicago. After they leave the station Grandma enrolls her into school on the first day she arrives! Mary Alice sits next to Mildred Burdick who Grandma says to stay clear of but gets into deep trouble with and her horse ends up losing her horse and having to walk miles to get home. And that’s the end of this chapter. The 2nd chapter is Vittles n’ Vengeance.It was Halloween time in grandma’s town which meant pranks going for weeks and half the privies are going to be on the ground be the time Columbus Day is over. There was a letter sent out from the school saying there is going to be a party and to bring refreshments. The first prank that had happened to them was when they put twine around her t ail and put a can at the end. Grandma made a horrid smelling glue to use on the pranksters and we set off to make a trap, we waited in the cob house for the pranksters to come and when they did they fell over the wire and the leader got glue on his head and he fell on his nose and lost his knife.We went to old man Nyquist’s house for pecans but he says we can only have pecans off the ground so grandma drives his tractor into the tree so pecans would fall! They also went into the Pensingers backyard to take some pumpkins! At the party Grandma served pumpkin and pecan pies and when Augie Fluke came for some grandma saw Augie with his broken nose, his scabbed bald head, and served him with his own knife. And that’s the end of this chapter. The name of this chapter is A Minute in the Morning. This chapter is about Armistice Day and of the turkey shoot.At the turkey shoot the woman are selling burgoo and the men are practicing shooting turkeys. Grandma tries to make the ric her people pay more and let the poor people not have to pay at all. All the money is said to go to charity and this year Miss Abernathy is the charity. At a certain time in the day everyone put their hand over their heart, stood east, and thought about the people who died for us. That was the end of their day. The 4th chapter is Away in a manger. It is Christmas time in grandma’s town and the school is going to do a Christmas program at the church.Grandma and Mary Alice went out to trap fox but even though Mary Alice doesn’t like the trapping and the screams of the fox she doesn’t want Grandma alone. Mary got the part of Mary for the Christmas program. During the Christmas program the baby Jesus screams, but it’s supposed to be a doll, the baby is a Burdick. Joey came to visit for Christmas! They had a great Christmas. Hearts and Flour is the name of this chapter. It starts out with Mrs. Weidenbach asking Grandma to make cherry tarts for the DAR because W ashington birthday tea.There is going to be a valentine exchange at the school and there is also a new boy named Royce and everyone has a little crush on him. The next day when Mrs. Weidenbach comes again Grandma says that the party has to be at her house or she can by some cherry tarts. At the valentine exchange Ina-Rae got three more valentines than anyone else and one of them is from Royce and that makes Carleen go ballistic. At the party Grandma is really dressed up and Mrs. Willcox and Aunt Mae Grizzwald were there. When everyone was there it turned into a disaster because Mrs. Weidenbach found out that she is a Burdick!That’s the end of that chapter. A Dangerous Man is the 6th chapter. It is March and Mary Alice is 16 and she got a dollar from her mother. One day Bootsie showed Mary Alice her kitten and Mary Alice named it April. A man came by one day and asked if he could rent a room and Grandma charged him $2. 50 a day! Mary Alice wanted Royce to come over to â€Å"s tudy† math together and he said OK. When he got there they heard a scream from the attic and out came Maxine Patch with only a snake around her and a flower in her hair and then Royce left. That was a crazy chapter. Finally my favorite chapter Gone With the Wind.School is almost out and out of nowhere the siren on the water tower went off and Mary Alice didn’t know what was happening. Everyone was heading towards the basement Mary Alice saw Grandma and had to make sure she was ok. They were both inside and Grandma told Mary Alice to go to the south west corner and we were both sitting down when Grandma let go of Bootsie and April. Grandma said that after Mary Alice leaves she’s going to turn it into a rooming home. That’s the end of that chapter. The last chapter is Ever After. When Royce and Mary Alice get married at Grandma’s house. They lived happily ever after.

Twelve Angry Men the Jury System Abstract Juries are supposed to be fully prepared for their tasks prior to sending them into deliberation, and this is the responsibility of the judge presiding in any case. However, the film Twelve Angry Men shows that in the 1950s the judge may fail to fully educate the jury regarding the concept of reasonable doubt. Moreover, even in todays system of justice there is confusion as what reasonable doubt really means and how it should be applied. Introduction When accused of wrongdoing or of a specific crime, American citizens are afforded certain rights thanks to the system of democracy in the United States. A trial by jury with jury members made of ones peers is the right that plays the overwhelmingly salient role in the movie 12 Angry Men. This paper delves into the jurys role in the movie along with the role of a jury in the American justice system. The thesis: a) the American system of justice has come a long way since the 1950s, when judges did not necessarily explain to juries that the accused cannot be convicted unless there proof beyond a reasonable doubt that he or she is guilty; and b) there are legitimate questions raised as to what reasonable doubt really means. The Jury System and 12 Angry Men The make-up of the Jury in 12 Angry Men was vastly different than would be expected today. It is quite likely that a jury today in a case like this would be made up of nearly half women, and if the accused wasShow MoreRelatedRacism, Discrimination, And Prejudice1458 Words   |  6 Pagessomething that some people used to get more work done, it was a crucial part in the economy and production throughout the states.
