question 1
5 pts
what is a hypertonic solution?
a solution with lower osmotic pressure than body fluids
a solution that causes cells to swell due to water intake
a solution that has greater osmotic pressure than body fluids
a solution with the same osmotic pressure as body fluids
question 2
5 pts
what occurs during the process of mitosis?
threadlike chromosomes become visible as the cell prepares to divide
the cell dies and is replaced by a new one
the cell takes in nutrients from its environment
the cell produces energy through respiration

Explanation:

• Question 1: A hypertonic solution has a higher osmotic pressure than body fluids. Osmotic pressure is related to the concentration of solutes. In a hypertonic solution, there are more solutes outside the cell compared to inside. This causes water to move out of the cell (via osmosis), which is the opposite of what happens in a hypotonic solution (where cells swell due to water intake) or an isotonic solution (same osmotic pressure as body fluids).
• Question 2: During mitosis, which is a type of cell division, threadlike chromosomes become visible as the cell prepares to divide. Mitosis is about cell division to produce two daughter cells with the same genetic material as the parent cell. Cell death (apoptosis or necrosis) is a different process. Taking in nutrients is part of normal cell function (not specifically mitosis), and energy production through respiration occurs in organelles like mitochondria throughout the cell's life (not a defining feature of mitosis).

Answer:

• Question 1: A solution that has greater osmotic pressure than body fluids
• Question 2: Threadlike chromosomes become visible as the cell prepares to divide
