The effect of different coloured lights on the rate of Photosynthesis Objective: To find out which colour of light provides the best consequences for the production of oxygen/ the rate of photosynthesis Background: In photosynthesis‚ there are two main parts‚ including light dependent and light-independent reactions. Plants use the energy from light for producing sugar‚ which is being converted into ATP by cellular respiration. They also are the only organisms that produce oxygen along with glucose

Effect of caffeine on Daphnia (Water fleas) Introduction- In this study I am going to investigate the effect of caffeine on Daphnia (water fleas) heart rate. I shall use daphnia as they would never have been exposed to caffeine before‚ unlike a human‚ who may have already developed a high tolerance to it. Another reason is that Daphnia have a very translucent body; therefore‚ it is relatively easy to see their heart under a microscope‚ which makes it easier to count the number of heartbeats

Lab Report: Animal Behavioral Diversity Biology 112 Lucas LLona 5-7-13 1) a. Based on background knowledge regarding beta fish‚ I believe that the male beta fish will be the first out of the two specimens to display any aggressive behavior. b. - Pectorals flap at rapid speeds when the beta fish is uncomfortable and appears agitated. - The gill cover expands in size when the beta fish is uncomfortable. - Caudal fin moves quickly when agitated and also determines how quickly the specimen

pressure. This can lead to heart and circulation problems. Hypothesis: Daphnia subjected to a caffeine solution will show a rise in heart rate as caffeine is a stimulant that speeds up the body affecting the nervous system and rate in which the nerve pulses are sent and received in humans. (Caffeine increases the heart rate of Daphnia. ) Null Hypothesis: There is no significant difference between the heart rate of Daphnia in distilled water compared to that in caffeine.
