Explanation:
Answer:
Chloroplast.
Explanation:
This is what I believe it is since we're obviously talking about an animal cell and NOT a plant cell like it says. Animal cells do not contain chloroplast.

Answer:
Extension
Explanation:
Polymerase chain reaction is given by Kary Mullis and it contains three steps denaturation, annealing, and extension. In denaturation, the temperature is raised to 96° c so that the DNA can denature.
In annealing, the temperature gets reduced to 55°c so that the primer can bind to the complementary sequence. In extension, Taq polymerase is used to extend the new strand.
This enzyme is isolated from thermophilic bacteria and the temperature here is raised to 72°c so that the enzyme can extend the primer and make the complementary strand. So the right answer is extension.
This would be Mitosis.
Mitosis results in two diploid cells.
Meiosis, on the other hand, results in four haploid cells.
