To investigate the effect of different caffeine concentration on the heartbeat rate of Daphnia at room temperature. Introduction: Caffeine is found‚ and produced in many plant species to function as a natural pesticide‚ and as an inhibitor of seed germination of other nearby coffee seedlings to give it a better chance of survival. Caffeine is able to paralyze and kill certain insects upon feeding on the plants that produce caffeine. Coffee‚ tea and cocoa are common caffeine-containing

The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

Effect of varying Temperatures on Enzymatic Activity of Bacterial and Fungal Amylase and hydrolysis of Starch Abstract This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch and placing the solution of amylase and starch in various temperatures of water. After a certain amount of time- different amount of time needs to be used in order to have reliable results- iodine is added

Jars were filled with a 100ml of federalized water‚ and a mark at the 100ml was made as indication to ensure the correct amount of water was given if the jars needed to be topped up. With a Q-tip‚ 10 green Lemna leaves with growing roots were placed into each of the ten designated jars. The five room temperature jars were placed into

Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location‚ seasonal variations‚ albedo of the place‚ contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary‚ operating at a smaller scale. Latitude

homeostasis to regulate control systems such as body temperature‚ osmotic balance‚ blood pressure‚ blood glucose and respiratory gases in tissues. This report will focus on thermoregulation‚ which is the ability of an organism to keep its body temperature within certain boundaries‚ despite the fluctuating external environment. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body to maintain a core body temperature of approximately 36.7 degrees celsius‚ despite the

Results The diameter of the cylinder (D) is 0.01m and the length of the heater (L) = 0.07m. The emissivity of the surface was 0.95 and the Stefan Boltzmann constant was 56.7x10-9 Wm-2K-4. The room temperature was assumed to be 25°C which is 298.15K.
