Siddharth Tirumala Mrs. Kiriazis IB1 Biology 22 August 2013 Diffusion Lab Write-Up Research Question: How does the temperature of the water affect the diffusion of food coloring? Hypothesis: Food coloring will dissolve faster as the temperature of the water increases. Variables: Name of Variable | What is it? | How is it measured? | Units | Range of the data | Independent | Temp. of Water | Thermometer | oC (Celsius) | | Dependent | Rate of diffusion of food coloring | Stopwatch

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

This organelle contains enzymes for intracellular hydrolysis of food molecules. Lysosom 4. This organelle takes in food molecules and oxygen and can transfer the food energy to ATP batteries‚ which will eventually collision energy for chemical reactions. Products of these events are carbon dioxide and water. Mitocondria 5. These organelles

Observance of Artificial Selection: Technical Study of Wisconsin Fast Plants 5th and 6th period AP Biology Due: 12/16/13 Abstract This experiment was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism ’s traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it
