1. Rank the following levels of biological organization (Chapters 1 and 2) in order from smallest (or lightest) [1] to largest (or heaviest) [8]. Place a number from 1 to 6 in each blank; each number can be used once. (3 points) one carbon atom one sugar molecule a forest ecosystem one bacterial (prokaryotic) cell an oak population one human skin cell You are conducting an experiment to determine the optimal (best) amount of antibiotic drug to stop a bacterial growth. You apply 0, 5, 10, 15, or 20 micrograms of antibiotic per bacterial plate. You have 10 plates for each amount of antibiotic, for a total of 50 plates. You keep the following the same during the experiment-type and amount of starting bacteria, amount and type of nutrients, amount and type of light, size of plates, and temperature. You take data at the end of the experiment on number of bacterial colonies and sizes of colony growth. (4 points) .What is your independent variable(s)? 2. What is your dependent variable(s)? What is your control group(s)? What is (are) the controlled variable(s)? ond causation been
