Question

The separation of populations by a barrier such as an ocean is called

A. geographic isolation.
B. temporal isolation.
C. genetic equilibrium.
D. behavioral isolation

Why are common names not always useful to biologists?

A. They are in Latin.
B. They are too long.
C. They can apply to more than one animal.
D. They require the use of a dichotomous key.

Answer 1

a.geographic isolation because the earth made it that way not man so it would be that way.
c.they can apply to multiple names just not one just like teens you slang there's not just one word for one thing they do

Answer 2

Answer:

1: A. geographic isolation

2. C. They can apply to more than one animal.

Explanation:

1: Separation of populations of the species by any physical barriers such as rivers, mountains, oceans etc. is called as geographical isolation. Geographical isolation is often followed by accumulation of variations in the separated species with time. Gradually, the separated populations evolve as two individual species as they cannot interbreed to produce fertile progeny.

2. Common names of organisms are given by local people and do not follow any scientific basis of nomenclature. One name can be given to more than one animal or plant leading to confusion. Lack of standard rules for nomenclature, possible repetition of common names make them useless for biologists.
