Question

how does the cell membrane maintain homeostasis within the cell? by storing nutrients by synthesizing proteins by producing energy by controlling the internal environment through selective permeability during diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will move across the membrane to the inside of the cell continue to move across the membrane in both directions move across the membrane to the outside of the cell stop moving across the membrane cell membrane changes shape to expel waste or hormones. choose choose protein pumps diffusion exocytosis osmosis endocytosis process by which a substance is taken up by a cell. select the correct answer. this process is called phagocytosis and requires energy from the cell.

Explanation:

1. The cell - membrane maintains homeostasis by controlling the internal environment through selective permeability. It regulates the movement of substances in and out of the cell. Storing nutrients is mainly the function of organelles like vacuoles, protein synthesis occurs in ribosomes, and energy production is mainly in mitochondria.
2. During diffusion, when the concentration of molecules on both sides of a membrane is the same (equilibrium), the molecules will continue to move across the membrane in both directions in a random motion, but there is no net movement.
3. The process by which a cell membrane changes shape to expel waste or hormones is exocytosis. Endocytosis is the process by which a substance is taken up by a cell. Phagocytosis is a type of endocytosis where large particles are engulfed.

Answer:

1. By controlling the internal environment through selective permeability
2. continue to move across the membrane in both directions
3. Exocytosis
4. Endocytosis
