Question

1. the relatively constant internal physical and chemical conditions that all organisms must maintain to survive is known as a. osmosis. b. endocytosis. c. homeostasis. d. exocytosis. 21. solute particles move from an area of higher concentration to an area of lower concentration in a process called a. osmosis. b. endocytosis. c. diffusion. d. equilibrium.

Explanation:

• For question 20, homeostasis is the maintenance of relatively constant internal physical and chemical conditions for survival. Osmosis is the movement of water across a semi - permeable membrane, endocytosis is the process of taking substances into the cell, and exocytosis is the process of releasing substances out of the cell.
• For question 21, diffusion is the movement of solute particles from an area of higher concentration to an area of lower concentration. Osmosis is specifically about water movement, endocytosis is about cell uptake, and equilibrium is a state of balance.

Answer:

1. C. homeostasis
2. C. diffusion
