The piece of cheese in the refrigerator had the least amount of chemical change.
- Moulding occurs on substances which are warm and moist
- Mold thrives in warm and humid places
- In refrigerators, the environment is cool and dry
- This environment hinders the growth of mold
- The bacteria and fungi require optimum temperatures to flourish, which is not present in a refrigerator
- The cheese placed outside and on the counter will grow mold as those environments do not arrest the growth of mold
- Refrigeration ensures that food is not spoilt
Therefore, the least amount of chemical change takes place on the cheese placed in the refrigerator.

Answer:
B. plasma membrane
Explanation:
Both plants and animals are eukaryotic organisms, it means that their cells contain 1-a nucleus that has linear chromosomes and 2-membrane-bound organelles such as mitochondria and endoplasmic reticulum. Moreover, chloroplasts are organelles found in the cells of plants and algae. On the other hand, bacteria are prokaryotic unicellular organisms that have neither an envelope-enclosed nucleus nor other specialized organelles. Most bacteria contain a genome composed of a single DNA molecule (i.e., one circular chromosome).
Answer:
B. isolation by vicariance
Explanation:
Vicariance is one of the biological processes that cause the isolation of a population of a species by a geographical barrier. These geographical barriers such as river, valley, causes physical physical isolation of organisms. Over time, these subpopulations of the ants that are separated by flood, undergo speciation to form new species.
