Answer:

No, they could not interbreed.

Explanation:

When a group of squirrels separate from each other and develop its unique characteristics, this is known as speciation. One type of speciation is allopatic speciation in which one squirrel's species separate into two separate groups and isolated from each other because of the physical barrier. This physical barrier can be a mountain range or waterway and makes it impossible to breed with one another. Each squirrels species develop unique genetic characteristics due to change in habitat and genetic variations are transferred to their offspring.

Answer:

The correct answer is B. the two strands of DNA must separate.

Explanation:

DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.

The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.

After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.

Infer: How might the size of a group affect its defense?

uysha [10]

I don't know exactly what you mean but the size of a group affects its defense because there is a larger group. Therefore, more people would be protecting it, adding more to its defense.

Which of the following describes a relationship of mutualism?

Reika [66]

Oxpecker birds eat parasitic ticks off the backs of zebras is an example of mutualism.
Mutualism is defined as a relationship between organisms in which both the individuals involved are benefitted from each other.
In the case of oxpecker birds and zebras, the oxpecker birds benefit as they get their food from the parasitic ticks living on the zebra and the zebras benefit as the birds help them to get rid of the parasites.
In this way, both these organisms are involved in a mutualistic relationship.
