Astudent argues that being seperated geographically is the only way for speciation to occur. why is he wrong?
a. speciation does not usually rely on geographic isolation.
b. speciation can occur from biological forces as well.
c. speciation can occur from variation as well.
d. speciation does not result from adaptive radiation.

you!

Answer;

B. Speciation can occur from biological forces as well.

Explanation;

-Speciation involves the formation of new and distinct species in the course of evolution that are reproductively isolated from one another. It involves the splitting of a single evolutionary lineage into two or more genetically independent lineages. It occurs when groups in a species become reproductively isolated and diverge.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
