Answer:
DNA polymerase.
Explanation:
DNA replication may be defined as the process of formation of daughter DNA from the template DNA strand. The process of DNA synthesis occurs in the 5' to 3' direction.
The enzyme responsible for DNA replication is DNA dependent DNA polymerase or DNA polymerase. This enzyme moves in 5' to 3' direction. DNA pol III is main replicating enzyme in prokaryotes and DNA pol alpha initiates DNA replication in eukaryotes.
Thus, the correct answer is option (a).
A mutation is any alteration in the genetic material (nucleotide sequence) of an organism. Mutations can be neutral, harmful, or beneficial depending on the environment in which the orgasm lives.
- In this case, the mutation IS HARMFUL because the organism is not more able to break down starch.
- The deleterious mutations are eliminated (selected) by natural selection.
- Beneficial germline mutations can eventually be inherited, increasing their frequency in the population.

C. be more susceptible to disease and famine.
this is because when a population experiences the bottleneck effect, the population is cut down significantly in size.
The correct answer is the Galápagos Islands.

Explanation: Carbon dioxide is released into the air by organisms, such as animals that undergo cellular respiration. In other words, we breathe out CO2 as a waste product.
