an animal cell has a 0.9% saline environment is placed into a solution that is 9% saline. what will happen to the cell
a. cell will swell and burst
b. cell will shrink or crenate
c. nother will happen to the cell as long as it is still alive

Explanation:

1. Mitochondria are the power - houses of the cell, converting food energy into ATP through cellular respiration.
2. Chloroplasts are the sites of photosynthesis in plant cells, converting light energy into food energy (glucose).
3. When an animal cell in a 0.9% saline environment is placed in a 9% saline (hypertonic) solution, water will move out of the cell by osmosis, causing it to shrink or crenate.

Answer:

1. a. Mitochondria
2. b. Chloroplast
3. b. Cell will shrink or crenate
