Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

the net movement of water will be leaving the hypertonic solution. Lastly‚ an isotonic solution entails no net movement of water across a semi-permeable membrane as the two substances involved display osmotic equilibrium. AIM To observe the effect of solutions different levels of NaCl concentration on potatoes‚ considering the process of osmosis METHOD (see ‘Potato Osmosis’ – exercise document) Table of NaCl-H2O Dilutions NaCl Solution / ml ±1 100 75 50 25 0 Distilled H2O/ ml

1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask was cooled in a beaker in the water of room temperature. The solid was formed in the mixture and the flask was shaken until it dissolved. The flash was rinsed with 15 mL dichloromethane and it was added to the separating funnel. 10 mL of water was added to the funnel and shaken to mix the layers.

QUESTIONS 1. What are other sources of glycogen? Of starch? a. Other sources of glycogen- Aside from the liver‚ it can also be found in skeletal muscles (for energy during strenuous exercise). It also occurs in tissues including adipose tissues‚ heart muscles‚ kidneys and the brain. It is also found in yeast‚ bacteria‚ fungi‚ molds and algae‚ oysters‚ and shellfish. b. Other sources of starch- Foods that are high in starch include breads‚ grains‚ cereals‚ pasta‚ rice‚ potatoes‚ peas

as its shape. The structure of an enzyme and its ability to function exists because it binds to an active site‚ thus increasing the reactivity of the enzyme and allowing for the reaction to speed up more quickly. However‚ the regulation of enzyme activity‚ which is catered towards attention to sensitivity in changes to catalysis as well speed of a catalyzed reaction‚ is monitored

Cesar Bizarroque Wesam Daker Bio 1107k-11 10/25/14 How pH levels impact tyrosinase activity Abstract: The purpose of our research utilizing the different pH levels was to test how a specific pH level would impact tyrosinase activity. First we added 4.0 mL of pH in each corresponding test tube and then added 0.5 mL of substrate (catechol) into each test tube. In the instructions it says to apply your 0.5 mL of tyrosinase (potato extract) as well but you have to blank the spectrophotometer before
