Question

solutions play an important role in cells. cells are filled with cytoplasm, a jelly - like liquid solution. cytoplasm is composed of many solutes—like ions, sugars, and proteins—dissolved in water. these solutes are used in cell processes like protein synthesis and cellular respiration. the human body fluids surrounding body cells typically contain about the same solute concentration as cytoplasm does, so body cells generally remain at equilibrium. however, if a cell is surrounded by an extracellular solution that does not have the same concentration as the cytoplasm does, water molecules will pass through the cell membrane to the more concentrated solution. select the true statements. water is the solvent in cytoplasm. osmosis cannot occur in body cells. solutes in cytoplasm can be used for protein synthesis. body cells are typically at equilibrium with their extracellular environment.

Explanation:

• For "Water is the solvent in cytoplasm": The text says cytoplasm has solutes (ions, sugars, proteins) dissolved in water, so water is the solvent.
• For "Osmosis cannot occur in body cells": The text states water moves through cell membrane (osmosis) when concentrations differ, so this is false.
• For "Solutes in cytoplasm can be used for protein synthesis": The text says solutes are used in cell processes like protein synthesis, so this is true.
• For "Body cells are typically at equilibrium...": The text says body fluids have same solute concentration as cytoplasm, so cells are at equilibrium, this is true.

Answer:

A. Water is the solvent in cytoplasm.
C. Solutes in cytoplasm can be used for protein synthesis.
D. Body cells are typically at equilibrium with their extracellular environment.
