Question

which statement best supports the answer to part a? exocytosis is the release of foreign substances, such as bacteria, from within the cell. diffusion is an essential part of our immune system and is responsible for maintaining balance. phagocytosis, or \cell eating,\ involves the cell membrane engulfing large particles such as bacteria and destroying them. homeostasis involves maintaining stability by keeping the concentrations of solutes equal on both sides of the cell membrane.

Explanation:

Homeostasis is about maintaining a stable internal environment, not just equal solute concentrations across the cell - membrane. Diffusion is a passive transport process and not directly an essential part of the immune - system for maintaining balance. Exocytosis is the release of substances from the cell, but not typically foreign substances like bacteria. Phagocytosis is the process by which cells engulf large particles such as bacteria and destroy them, which is an important part of the immune response.

Answer:

Phagocytosis, or "cell eating," involves the cell membrane engulfing large particles such as bacteria and destroying them.
