Question

This cell is in a(n) _____ solution.

Options:
A) Hypertonic
B) Hypotonic
C) Isotonic
D) Osmotic

Answer 1

In an isotonic solution, the extracellular fluid has the same osmolarity as the cell, resulting in no net movement of water. In a hypertonic solution, the extracellular fluid has a higher osmolarity than the cell, causing water to leave the cell. In a hypotonic solution, the extracellular fluid has a lower osmolarity than the cell, causing water to enter the cell.

Step-by-step explanation:

In an isotonic solution, the extracellular fluid has the same osmolarity as the cell. There will be no net movement of water into or out of the cell in an isotonic solution. In a hypertonic solution, the extracellular fluid has a higher osmolarity than the cell's cytoplasm, causing water to leave the cell. In a hypotonic solution, the extracellular fluid has a lower osmolarity than the cell, causing water to enter the cell.
