Marsupial mole rats evolved in New Zealand in the 1700s and had few natural predators so they overpopulated the area. Scientist
r-ruslan [8.4K]

Answer:

C. Some marsupial mole rats had a natural immunity to the virus.

Explanation:

According to Darwin's evolutionary theory, over time some of marsupial moles may have acquired natural immunity which evolves as an adaptive trait in the population. Since these organisms have more chance to survive and reproduce (survival of the fittest), they will likely transmit the natural immunity to the next generation .

When the Grand Canyon was forming, a population of squirrels were separated into two groups. The north side of the canyon is at
mariarad [96]

Natural selection lead to different species when the squirrels were separated, some of them acquired traits better suited for their new environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.

Explanation:

The speciation in the squirrels due to the barrier in canyon occurred due to this. Such speciation is called allopatric speciation.

Speciation leads to formation of new species from the existing species due to change in their habitat or physical structure.

The squirrels on the two different side of canyon adapted to the habitat they are in. Their reproductive cycles, habitat and adaptation mode has become different due to the change in environment.

The species of squirrels became two as they reproduce and passed on the traits for survival in the environment which they had adapted.

The squirrels have become <em>reproductively isolated</em> also.

Genetic divergence takes place due to natural selection as squirrels arenow two different species.

This is a two-part process that ends in the assembly of proteins at the ribosomes within cells. The first part
mariarad [96]

Answer:

The protein synthesis.

Explanation:

The question is not complete, here is the complete question:

This is a two-part process that ends in the assembly of proteins at the ribosomes within cells. The first part, transcription, begins in the nucleus, when the DNA code is transferred to mRNA. The second part, translation, takes place at the ribosomes, where both mRNA and tRNA work to assemble proteins.

The events in the question are describing protein synthesis.

I hope this answer helps.
