In some states, populations of mule deer (Odocoileus hemionus) and white-tail deer (O. virginianus) can occupy the same forest h
slega [8]

Answer:

The correct answer is option B) "habitat isolation".

Explanation:

The two populations of ticks herein described have preference in one of two populations: either over mule deers or white-tail deers. One term that might be applied to describe these populations is habitat isolation. Habitat isolation occurs when the chances of mating between individuals of the same species are lowered because of differences in habitat preference. This is the case for the two populations of ticks, where because of differences in host preference, the ticks that feed from mule deers are isolated from the ones that feed from white-tail deers and vice-versa.

aksik [14]

Answer:

Insertion

Explanation:

Mutation is a phenomenon in which the nucleotide sequence of a gene in DNA is changed into a new sequence due to insertion, deletion or  exchange of a gene segment.

Insertion is a type of  mutation in which one or more than pne base sequence in added into the DNA of an organism. This insertion may or may not be dangerous depending on the place of insertion and how it is causing adverse effects on the protein product of the gene.

Here is an example of insertion mutation:

Base sequence: AUG GCC TGC

Product:           met     ala      gln

Insertion:

Base sequence: AUG GCC   C TG     C

Product:              met     ala      Leu

So we can see that the product protein is changed because of insertion.

Hope it helps!
