Explanation:

1. Cholera is spread through contaminated food/water.
2. Iodine stains starch. Chromoplasts contain starch.
3. Ribosomes produce proteins in both prokaryotic and eukaryotic cells.
4. Overuse of antibiotics leads to antibiotic resistance.
5. Fecal transplantation involves implanting donor gut bacteria.
6. Adaptation is a trait that helps an organism survive.
7. As species number increases, ecosystem stability increases.
8. Microbiome is a collection of microorganisms in and on the human body.

Answer:

1. A. Drinking contaminated food/water
2. B. Chromoplasts
3. C. Ribosomes
4. D. Overuse of antibiotics
5. A. fecal transplantation
6. D. adaptation
7. B. Increases
