Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

were engulfed by the primitive ancestor of eukaryotic cells in a arrangement called endosymbiosis. Mitochondria have evolved over thousands of years‚ but still share characteristic with bacteria such as: their genome is a circular molecule ‚ have little non-coding DNA‚ and have 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

sun-sensitive people‚ reducing the risk of breast cancer and other diseases‚ preventing asthma attacks caused by exercise‚ as well as many other uses. Chlorophyll is the green‚ light-capturing pigment found in plants. Chlorophyll (like heme in red blood cells) is an example of porphyrin. In this experiment‚ chlorophyll and ß-carotene were isolated using the technique of column chromatography. Column chromatography is a method used to separate and purify components in a mixture. In gravity column chromatography

catalase in their cells. Catalase Foam Thickness 50 μl of each tissue extract was added to the cut up tissues‚ 1 mL of water was added to it and each placed into a separate test tube. After setting up the test tubes‚ 1 mL of hydrogen peroxide was added to each tube of extract. The thickness of the foam layer that was created in each tube was measured in millimeters. The effect of Temperature on Catalase The effect temperature had on the action of each catalase. In the liver cells‚ the hypothesis

Introduction Human cilia play a critical part in human processes. Human cilia are hair-like projections that extend from the surface of a cell. Cilia are capable of rhythmic motion and acts together from separate strands so that the cell is capable of movement. Flagella are a whip-like structure that is found in cells as well that allow for the movement of the cell. Human cilia are characterized as having “metachronal rhythm" and this means is a rhythm that "changes time" to produce wave. The beating

How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1. Create the flubber. 2. Split the flubber evenly into 2 parts. 3. Roll both parts into balls. 4. Set the tra

Cerevisiae is a unicellular eukaryotic Fungi means that is made up of one cell with a nucleus(“What is Yeast”).Yeast is a very practical product that is used in mainy way like when baking Yeast helps raise the dough and also yeast is used in the process of making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different types of carbohydrates which are known as Glucose
