question 9
why do old vegetables, such as celery, carrots, and radishes, get crisp again when you put them into cold water?
a because it kills bacteria that are digesting them.

question 10
why should avoid drinking high salt content water (sea water)?
a because it is hypertonic to the body and will pull water out of the body
b because it is hypotonic to the body and will push water into the body and the cells
c because is contains deadly bacteria
d because it is bad for the heart muscle and brain cells

Explanation:

• Question 8: A hypertonic solution has a higher solute - concentration than the potato cells. Saltwater has a higher salt (solute) concentration compared to potato cells, making it hypertonic.
• Question 9: Old vegetables have a higher solute concentration (such as sugars) inside their cells. When placed in cold water, water moves into the cells by osmosis, making them crisp again.
• Question 10: Seawater is hypertonic to the body's cells. When consumed, water will move out of the body's cells due to osmosis, leading to dehydration.

Answer:

• Question 8: A. Saltwater
• Question 9: C. because they contain sugars and the water moves back into them by osmosis.
• Question 10: A. Because it is hypertonic to the body and will pull water out of the body
