know that all organisms consist of basic units of matter called atoms. When atoms are bonded together they make up a molecule. Often associated with nonliving things are inorganic molecules‚ and associated with organisms are biomolecules. Today in lab‚ a series of tests were ran. Tested were the biomolecules of cells which are lipids‚ sugars‚ proteins and starch. The purpose of these tests were to test for the presences of cellular biomolecules. Some of the things that fat consist of are one glycerol

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

Week 3 Time Value of Money and Valuing Bonds Chapter 6 55. Amortization with Equal Payments Prepare an amortization schedule for a five-year loan of $36‚000. The interest rate is 9 percent per year‚ and the loan calls for equal annual payments. How much interest is paid in the third year? Answer: $2‚108.52 56. Amortization with Equal Principal Payments Rework Problem 55 assuming that the loan agreement calls for a principal reduction of $7‚200 every year instead of equal annual payments. Answer:

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water
