their genes tightly packed with few intergenic regions between genes. Furthermore‚ mitochondria are organelles that contain a separate set of DNA from the rest of the cell and the body. Mitochondrion DNA contains 16‚569 nucleotides and contains 37 genes. These genes are all involved in the production of energy and storage of ATP. The point of this lab is to understand how DNA can mutate over

Enzymes are used to increase the rate of specific reactions in the body. Catalase‚ a specific enzyme‚ speeds the breakdown of hydrogen peroxide‚ a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms‚ including chicken liver. The purpose of this experiment is to determine what changes in pH‚ temperature‚ and enzyme concentration have on the rate catalase works to break down hydrogen peroxide

Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

Two milligrams of it is measured and placed into a watch glass by which grams scale. From that point‚ a capillary tube is loaded with the fine powder by tapping the open end of the tube into the glass plate which the powder is located. Therefore‚ locate the powder at the bottom tube by tapping the closed and of the tube on the table top

energy captured from the sun into chemical energy that can be used to synthesis glucose is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused

one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My hypothesis was‚ if I increase the amount of paper towels‚ then the germination rate would increase too. We observed the petri dishes in class and we would add 2 ml of
