The Five Themes of Biology Transfer of energy: the movement of energy from one place to another‚ matter can not be created nor destroyed Bioheat transfer: heat transfer in biological systems. How heat moves from one compartment‚ be it within the body or external to the body‚ to another compartment in the body Osmosis: Water moving from high concentration to a low concentration Diffusion: Particles moving from high concentration to a low concentration Unity and Diversity: how things are similar

AP biology FRQ Courtney DeMane 1.22.13 block 7 A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino‚ carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure‚ there are 4 levels. The first one being the primary level. These are made

the algae stimulate a virus that causes the tumors. Scientists have been trying to understand the pathology of these tumors. The tumors were most commonly located on the turtle’s heads‚ eyes‚ and flippers. According to Celia Smith‚ UH Mānoa Marine Biology Professor‚ “Many hypotheses were offered to explain the tumors‚ but we kept coming back to the observation that urban reefs—those near dense populations—are the sites with greater numbers of sick turtles. We had no mechanism for this disease” (Invasive

Biology laboratory work: Osmosis observation Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution By Jonas Kulikauskas Siauliai Didzdvaris Gymnasium Hypothesis: The more sugar in solution‚ the more potato mass will decrease. Aim: To see how potato mass will change at different concentration solution. Research question: How the mass of potato will change at different concentration solutions? Variables: Dependent: solution concentration. Independent:
