Ch. 5-2.3
Active transport

against concentration gradient
	low conc. to high conc.
requires cell energy(ATP)
carrier proteins
endocytosis
exocytosis
i.e.  Broccoli
		pulls Calcium (Ca+) into cells
		food high in calcium
Animals adapting:
	Hypotonic solutions
		i.e. distilled water
			100% H2O
			0% solute
		avoid cytolysis
		contractile vacuole
			uses energy(ATP)
			active transport
			i.e. paramecium
	Hypertonic Solutions
		i.e. salt water
		avoid plasmolysis/crenate
			sharks put more oil in cell
