Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

Name: Siti Nur Amalina binti Mohamad Sukri Class: M12E Title: Cell Respiration and Aquatic Animal Aim: To investigate the effect of a change in the temperature of water on the respiration rate of a goldfish. Research question: Does a change in temperature of water affect the respiration rate of a goldfish? Introduction: “The goldfish is a domesticated subspecies of a carp like fish called Carassius auratus. Goldfish are usually kept as pets‚ feeding on fish food‚ algae‚ plankton and other

Why are some colors of light more effective than other colors? Answer Photosynthetic saturation is the maximum rate of photosynthesis. What was the value for photosynthetic saturation in tomato leaves? Answer Light quality does not effect the rate of photosynthesis. Answer Based on what you know about photosynthesis‚ provide possible reasons for what causes photosynthetic saturation (these cannot be determined from the graph). Answer Which color

7/30/2015 Assignment [ print page ] Assignment Background Information: Scientists have found that almost all living organisms have a gene that codes for a protein called Cytochrome C. This protein is important in releasing energy from food. Scientists study similarities such as the gene that codes for Cytochrome C in hopes to learn more about the universal genetic code and the relationship between living organisms on Earth. Procedure: The charts below lists a portion of the amino acids found in

These units could only transmit from a single sensor channel‚ and were difficult to assemble due to the use of discrete components. The measurement parameters consisted of temperature‚ pH or pressure‚ and the first attempts of conducting real-time noninvasive

28/09/12 Grace Masters Woodlice Behavior Experiment Aim: To investigate the effect of light intensity on the behavior of woodlice (Porcellio scaber) in regards to their change in speed. Variables: Variable How can it be controlled? (IV) - Light intensity - The light intensity will be controlled by the knob on the lamp throughout the experiment. In addition‚ the light intensity will be controlled by closing the windows and doors in the classroom as well as turning

1. By exhaling out carbon dioxide into the straw on top of the bromothymol blue indicator‚ the solution will turn the color blue into a yellowish-green color. When there is a presence of something that is acidic the BTB indicator changes its color into yellow/green. So in this case‚ the water with BTB and carbon dioxide exhaled into the flask creates a carbonic acid. As an aerobic activity increase than the carbon dioxide rate increases as well. 2. By exercising more‚ one’s body requires more
