Which statement is correct about diffusion?

• It's very rapid over long distances.
• It's a passive process which molecules move from a region of higher to lower concentration.
• It requires an energy expenditure by the cell.
• It's an active process where molecules move from a region of lower to higher concentration.

Which describes the events of apoptosis?

• The cell's DNA & organelles become fragemented, the cell shrinks & forms blebs, the cell's parts are packaged in vesicles that are digested by cells like macrophages.
• The cell dies, it is lysed, its organelles are phagocytized, and its contents are recycled.
• The cell's DNA and organelles become fragmented, the cell dies, and it's phagocytized.
• The cell shrinks, dies, and the presence of its fragmented contents stimulate nearby cells to divide.

• The patient's red blood cells will shrivel up because the blood fluid has become hypertonic compared to the cells.
• The patient's red blood cells will shrivel up because the blood fluid has become hypotonic compared to the cells.
• It will have no unfavorable effect as long as the water is free of viruses and bacteria.
• The patient's red blood cells will swell because the blood fluid has become hypotonic compared to the cells.
