• Describe the electron transport chain - how it works and what it accomplishes - proton gradient forms and H+ pushes thru ATP synthase, creating ATP- formed from NADH and FADH2-electrons adopted by H20 (O2 is the last electron acceptor) • Explain what residual lung volume refers to and why it exists - Residual volume is the volume that is never exchanged. It is the amount of air left in the lungs after maximum exhalation. Residual volume exists because if not, our lungs would collapse....

what are the 4 postulates of natural selection? - 1. individuals vary in their traits 2. some of the variation is heritable 3. more offspring are produced than survive to reproduce 4. survival & reproduction are predictable; those with favorable traits reproduce most and pass their genes to the next generation what happens when a proton is absorbed by a molecule? - -it excites an electron into a higher energy state -the electron quickly drops to its ground state -releases the energy as l...

Why are cells small? - As the cell increases in size, materials diffusing in the cell will not be able to reach the core as efficiently as in a small cell. The higher the SA:V ratio, the less efficient a cell is. The bigger cell will have slower cellular signaling response What is cellulose? - Polysaccharide consisting of glucose monomers. The main constituent of a plant cell wall and of vegetable fibers Describe an effective experimental design to determine whether an environmental variabl...
