removing metabolic wastes‚ including carbon dioxide and nitrogenous waste‚ from the body. The are many substances that need to be excreted - almost any cell product that is formed in excess by the chemical process occurring in the cells must be excreted. However there are two products that are produced in very large amounts. Carbon dioxide from respiration. Nitrogen containing compounds such as urea. Where are these substances produced. Carbon dioxide is produced by every living cell in

Scientific Method - Mealworms Abstract The experiment is designed to determine which substrate‚ A (oat bran) or B (peat moss) will be better nourishment for a mealworm after exposed for 7 days. A total of 30 mealworms were placed in the substrates for a period of 7 days; 15 in substrate A and 15 in substrate B. The data was compiled and analyzed on day 7 to determine the change of mass in each of the mealworms. The experiment proved my hypothesis to be correct; the mealworms would not thrive

One advantage of the Scientific method is that it’s replicable. Scientists record their methods and standardise them carefully so as the same procedures can be followed in the future. Investigations are carried out in highly controlled‚ objective laboratory and repeated to gain further reliability. This is an advantage because repeated a study is the most important way to demonstrate the validity of an experiment. If the results of the repeated experiment are the same‚ then this affirms the truth

December 2012 1. Title and Author 1. The Effect of Extreme Temperatures on the Rate of Photosynthesis 2. Jeffrey Xia 2. Abstract A previous lab in which we conducted‚ tested whether or not the light intensity had an effect on the rate of photosynthesis. We concluded that light intensity did possess an effect on the rate of photosynthesis – the closer the experimental plant units were to the light source‚ the more experimental plant units exhibited the effect of gas exchange in photosynthesis.

It could be many things‚ it could be nothing or it could be something‚ we’re basically trying to find out what

usually framed in terms of heredity versus the environment. Such philosophical discussions influenced the topics that would be considered in psychology. But early philosophers could advance the understanding of human behavior on to certain. Their methods were limited to intuition‚ observation and logic. The eventual emergence of psychology as a science hinged on advances in the other sciences‚ particularly physiology. Physiology is a branch of biology that studies the functions and parts of living
