Select the correct statement about osmosis. a. osmotic equilibrium cannot be reached unless solute concentrations equalize across the membrane. b. if a dead cell is placed in a solution hypotonic to the cell contents, osmosis will not occur. c. osmosis is the diffusion of water molecules across a selectively permeable membrane.

c. Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Explanation:

Osmosis is the passive transport of water molecules from the region of their higher concentration to that of lower concentration through a semi-permeable membrane. Osmosis does not include the movement of solutes. When two solutions with different concentrations of solutes are separated by a semi-permeable membrane, water moves through the membrane from a hypotonic solution to the hypertonic solution until equilibrium is obtained. This process is called osmosis.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

and after water is usually warmed by the sun the water temperature raises and then evaporates .
