Question

question 1
which of the following best describes an isotonic solution?
a solution with a lower osmotic pressure than body fluids
a solution that has the same osmotic pressure as body fluids
a solution with a higher osmotic pressure than body fluids
a solution that causes cells to shrink due to water loss
question 2
what is the cytoplasm of a cell?
the genetic material found inside the nucleus
the rigid structure that gives the cell its shape
the fluid and organelles located between the cell membrane and the nuclear envelope
the outer layer that protects the cell from its environment

Explanation:

• For Question 1: An isotonic solution has the same osmotic pressure as body fluids. A solution with lower osmotic pressure is hypotonic, one with higher is hypertonic, and a solution causing cell shrinkage (due to water loss) is hypertonic (as water moves out of cells in a hypertonic environment).
• For Question 2: The cytoplasm is the fluid and organelles between the cell membrane and nuclear envelope. Genetic material inside the nucleus is DNA (chromatin/ chromosomes). The rigid structure giving cell shape (in plant cells) is the cell wall. The outer - layer protecting the cell is the cell membrane (or cell wall in plants).

Answer:

Question 1: A solution that has the same osmotic pressure as body fluids
Question 2: The fluid and organelles located between the cell membrane and the nuclear envelope
