Their thick fur and layer of fat help to insulate them against the extreme cold temperatures of their habitat.

Multiply 5730 years by 2 since two half-lives have gone by for carbon.
<u>Explanation</u>:
The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years
The half-life of carbon-14 is 5730 years.
In this manner, after
1 half-life there is 50 % = 1/2 of the first amount left.
2 half-lives there is 25 % = 1/4 of the first amount left.
25% is two half-lives.
Every 50% of life requires 5730 years.
So two half-lives require 2 × 5730
Answer: Option C
Explanation:
A biological species can be defined as the concept which includes the group of individual which lives in one or more population that can reproduce among each other to produce viable species.
Speciation is the phenomenon by which one group of species gets separated from another. The species gets diverge due to reproductive isolation or due to geographical isolation.
Hence, the correct answer is option C
