Answer:
<u>B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.</u>
Explanation:
The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.
The answer is D) codes for a specific trait . Hopefully its right.
Answer:
Option A , The allele for yellow is dominant to white
Explanation:
It is given that 23 percent of the sheep have white fat and 77 percent have yellow fat.
Thus, it is clear that sheeps with yellow fat is a dominant characteristics.
Usually, the frequency of homozygous recessive allele in a given population is represented by 
and here 
Frequency of allele for white fat 
While frequency of homozygous dominant allele and heterozygous dominant allele is represented by 
And here 
Allele for yellow fat 
Hence, option A is correct.
