Introduction Photosynthesis takes place in the chloroplast and is the use of sunlight energy for cell processes. It happens through a number of chemical reactions and the transfer of electrons. It is used as the source of energy (ATP) for plants. The reaction equation for photosynthesis is H2O + CO2 + (Light) (CH2O)N + CO2 In the Hill reaction‚ Robert Hill showed how chloroplasts in water can still function if there is light and an electron acceptor to release oxygen. He proved that the oxygen

The graph shows that the respiration rate does increase as the yeast concentration rises‚ but levels off and eventually reached its saturation point‚ or decline‚ which occurs at 8.5g. This decline may occur because there are too many yeast molecules in comparison to the glucose‚ which may lead to yeast cells hindering a collision thus lessening the reaction. The respiration rate increases as more yeast is added because it gives more opportunities for molecular collisions and so the amount of successful

will be addressed. Does heat speed up the enzyme reaction? The prediction is as more heat is applied more reactions will occur then at some point the heat will denature the enzyme as it reaches too high of heat. If an enzyme has been denatured it means the shape has been altered therefore cannot perform its function‚ many factors can cause this including high heat. The hypothesis is if temperature is increased the amount of activity rate will increase. The results for the rate of oxygen production

Introduction The profession as a police officer has many requirements one being the use of force. Police work requires this physical skill of police officers because the probability of a police officer requiring the use of force to control a subject is more likely than not. Situations or improper action during a situation can cause an officer or civilian to lose their life when the wrong use of force is applied. Many situations will dictate the amount of force required to control the suspect

investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1. Growth rates for pine seedlings in Batch I Experiment II A

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best

question was “How does exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both went up

In the experiment‚ the effect of light intensity on the rate of photosynthesis will be tested. Photosynthesis is the process in which autotrophic plants create their own food (energy) from sunlight. Photosynthesis involves three ‘ingredients’ or reactants‚ carbon dioxide‚ water‚ and light energy (sunlight). Carbon dioxide and sunlight come in through a leaf’s stomata which are tiny holes‚ and water is absorbed through their roots. When all of these reactants are combined in a plant’s chloroplasts

that no milk was added to the coffee within this experiment. If milk was added into the experiment‚ the rate of cooling would be noticeably faster than it is without adding the milk. This would result in larger k values. Also‚ the amount of water that was measured into the beaker may not be accurate due to the fact that human error can come into play. The effect of this would be that the rate of cooling of the coffee may actually be slightly higher or lower depending on whether less or more water
