Allopatric speciation would occur in .(A) One population that mates in May, and another that mates in June(B) Two populations separated by the Mississippi River(C) One population that feeds in tree branches, another feeds on tree trunks(D) A population with a mutation that turns fur a different color than usual

B) Two populations separated by the Mississippi River

Explanation:

Once organisms of the same species are geographically isolated (not living in the same territory) and thus unable to crossbreed like the two populations of organisms of same species separated by the Mississippi River, then Allopatric speciation occurs.

Option B.

Two population separated by missippi river.

Explanation:

Allopatric speciation occur when two populations of the same species become isolated from each other due to geographical changes.

Allopatric species are unable to interbreed due to geographical separation.

Two populations separated by missippi river is an example of allopatric speciation. The populations are geographical separated and the river is the barrier making them not to be able to interbreed with each other.

the answer is c

explanation:

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
