Across carrier protein
Against concentration gradient
in animal cells, the carrier proteins that transport sodium ions to extracelullar, and potassium ions into the cell are called (a) .
Osmosis refers to the net movement of water molecules from an area of (a) to an area of low water potential randomly through a selectively permeable membrane.
When red blood cells are placed in a (a) solution, water will diffuse into the cells by osmosis, causing
the cells to swell and finally burst.
When red blood cells are placed in a hypertonic solution, this will cause the cells to shrink. The red blood cells
are said to undergo ____________________ .

immediately.
