English 3/Boynton Crucible Act 3 WORKSHEET 1. ! Consider the setting as the act opens. How is the different from the setting of Act 2. What is Miller doing? The setting is in the vestry room of the Salem meeting house‚ serving as the anteroom of the General Court. The setting is different from Act 2 because the setting is finally out of the house‚ its not inside a room or Rev. Paris house at all. It has become not private at all. 2. As this act opens‚ what accusation does Giles Corey make? What

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

The Four Main Macromolecules Interestingly enough‚ all cells that build up an entire organism‚ such as the human body‚ only consist of water‚ inorganic ions‚ and organic compounds as three dominant components. Together‚ water and inorganic ions such as Sodium‚ Magnesium‚ Calcium‚ Phosphate‚ etc. make up around 70% of the cell’s mass‚ while organic compounds make up the rest. Unlike its other two counterparts‚ organic compounds contain carbon-hydrogen reactions that allow them to create‚ sustain‚

Biuret test. Introduction The purpose of this experiment was to identify the presence of macromolecules by using various positive and negative controls. The principle building blocks of living organisms are essentially constructed by carbon-containing molecules in cells. (Alberts‚ 2009) The macromolecules including lipids‚ carbohydrates‚ proteins‚ and nucleic acids contribute to the most distinctive properties on living organisms. Macromolecules are known as polymers which are constructed by small

Abstract The aim of the experiment is to test the existence of macromolecules which are carbohydrates‚ lipids‚ nucleic acids and proteins in given samples. The first experiment is to test the existence of carbohydrates in starch suspension and potato cell. If carbohydrate is present in starch suspension‚ the solution will turn into dark blue when iodine solution is added. If carbohydrate is present in potato cell‚ starch granules can be seen clearly under microscope when iodine solution is added

help to stabilize the overall structure. For example‚ insulin (a globular protein) has a combination of hydrogen bonds and disulfide bonds that cause it to be mostly clumped into a ball shape. Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. Dna And

test for starch macromolecules occurs when the solution turns dark brown when Iodine solution is added. 2. If there is glucose in the substance‚ the substance turns to an orange-yellow colour when Benedict’s Solution is added to it. The colour of the glucose solution when it is mixed with Benedict’s solution with heat is orange-yellow‚ while all of the sample solutions turn into a light blue or purple colour. We can therefore deduce that a positive test for glucose macromolecules is when the colour
