Answer:
E) founder effect and genetic drift
Explanation:
Dunkers moved to Pennsylvania and inhabited a new area to develop a new population. This new population might not have the same gene pool and the same allele frequencies for all the genes as present in the original population. The change in the allele frequencies of a population due to the colonization of a new area by a few members is called the founder effect.
The small size of the new population of Dunkers present in Pennsylvania was more likely to be affected by any chance event which could have added more uniqueness to their gene pool. This is called genetic drift. Therefore, the genetic uniqueness of their population from all the other populations and from their original population might be the result of founder effect and genetic drift.
Answer:
Carbon assimilation is directly proportional to oxygen production.
Explanation:
Carbon is assimilated in form of carbon dioxide in plants during photosynthesis. iI diffuses through the stomata to the intercellular spaces of the leaves. An increase in carbon absorption increases the amount of oxygen produced into the atmosphere since oxygen is a by-product of photosynthesis.
Answer:
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid.

The answer is cancer.
Cancer is an uncontrolled division of cells. The regulation of cell cycle is necessary for normal cell division. The first phase of the cell cycle is the G1 phase. If the G1 phase is affected, mistakes in this process lead to the uncontrolled division of cells called cancer.
