Final answer:
Osmosis is the diffusion of water across a semipermeable membrane. This process is important for maintaining homeostasis and involves different salt concentrations outside and inside the cell. Nonpolar molecules have no charge or partial charge. Permeable membranes allow any molecule to pass through, while semipermeable membranes allow some molecules to pass through but exclude others.
Step-by-step explanation:
Definitions:
- a. The maintenance of a constant internal body environment - Homeostasis
- b. A higher salt concentration than inside the cell - Hypertonic
- c. A lower salt concentration than inside the cell - Hypotonic
- d. The same salt concentration as inside the cell - Isotonic
- e. Not having a charge or partial charge - Nonpolar
- f. The diffusion of water across a semipermeable membrane - Osmosis
- g. Any molecule can pass through without hindrance - Permeable membrane
- h. Allows some molecules to pass through but excludes others - Semipermeable membrane
Step-by-step explanation:
Osmosis is the diffusion of water across a semipermeable membrane. When the environment outside the cell has a higher salt concentration, it is hypertonic. When the environment has a lower salt concentration, it is hypotonic. Isotonic refers to the environment having the same salt concentration as inside the cell. Nonpolar means a molecule has no charge or partial charge. Permeable membrane allows any molecule to pass through without hindrance, while a semipermeable membrane allows some molecules to pass through but excludes others.
