Answer:
There are three general types of symbiosis: <em>mutualism, commensalism, and parasitism.</em> Based on the nature of the interaction between organisms, symbiotic relationships are loosely grouped into one of these types. Mutualism is a mutually beneficial relationship in which both organisms benefit.
Pre-Cambrian Era. Earth formed and became a planet 600-3,300 million years ago.
Paleozoic Era. Ancient life. Volcanoes and mount formed.
Mesozoic Era. Middle life (Industrial Ages, Evolution of human technology)
Cenozoic Era. Present life
The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.
<h3>What is Allelic frequency?</h3>
The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.
The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:
2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.
∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.
The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.
Therefore, it is well described above.

Answer:
Polar Bears
Polar bears have white fur which helps aid in camouflaging against the snow. They also have small rounded ears that act as a shield letting no water in to freeze ear drums and reduce heat loss.
Black Bears
Black bears absorb heat through their black skin. Their thick fur and fat act as an insulation and their large bodies reduce heat loss.
They both use their large claws and teeth to catch prey and provide for themselves
