A. Geographical Isolation

Explanation - Geographical Isolation alludes to the physical obstructions that exist that shield two species from mating. For instance, a types of monkey that is situated on an island can't breed with another types of monkey on the terrain.

The water separates the two species by keeping them secluded from each other and make it unthinkable for them to breed. In this case, fishes of different ponds cannot breed because they are separated from one pond to another.

4vir4ik [10]

Answer:

This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:

1) GEL

2) DYE

3) DNA MARKER

4) LID

Explanation:

This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.

In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.

Before running the gel, it's important to make sure that there is LID covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool.
