Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
It is either blending inheritance or merging inheritance. They both mix the parents' genes to produce conditions for their future offspring.
The distribution of natural resources depends upon number of physical factors like terrain, climate and altitude. The distribution of resources is unequal because these factors differ so much over the earth.
Answer:
hey!!
Explanation:
The answer is 36
Mitosis is a cell division that produces 2 cells daughter that are genetically identical to both the other daughter cell and the parent cell. The process where the parent cell first duplicates its genetic material, then it divide so that both daughter cell receive the exact number and same DNA.
Therefore, the answer is 36, only 36 matches the description of genetically identical cells.
