Osmosis – the diffusion of water through a selectively permeable membrane
Cyclic electron flow – A route of electron flow during the light reactions of photosynthesis that involves only photosystem I and that produces ATP but not NADPH or O2.
founder effect – Genetic drift that occurs when a few individuals become isolated from a larger population, with the result that the composition of the new population's gene pool is not reflective of that of the original population.
Describe how molarity can be used as a measure of concentration of aqueous solutions – …
exergonic reaction – a chemical reaction that releases energy
biosphere – zone of life on Earth; sum total of all ecosystems on Earth
mortar and pestle – used for grinding chemicals
mutation – a change or alteration in form or qualities
Inheritance – transmission, from parents to offspring, of genes that specify structures and functions characteristic of the species

bacteriophage – virus that infects bacteria
transformation – The incorporation of new genes into a cell from DNA that the cell takes up from the surrounding environment.
