Answer: the answer is B
Explanation: Yellow bone marrow is involved in the storage of fats. The fats in yellow bone marrow are stored in cells called adipocytes.
What following ? actually the cell will gain more water by diffusion and will let more sodium chloride ions in because they will move from high concentration to low concentration
Answer:
Option C
Explanation:
Given ,
A1 allele is carried by
% people
Let us assume A1 s dominant genotype
This means ![p= \frac{70}{100} = 0.7](https://tex.z-dn.net/?f=p%3D%20%5Cfrac%7B70%7D%7B100%7D%20%3D%200.7)
Thus, frequency of allele in the given population is ![0.7](https://tex.z-dn.net/?f=0.7)
It is also given that the population is in Hardy-Weinberg equilibrium thus
![p+q=1\\0.7+q=1\\q = 1-0.7\\q= 0.3](https://tex.z-dn.net/?f=p%2Bq%3D1%5C%5C0.7%2Bq%3D1%5C%5Cq%20%3D%201-0.7%5C%5Cq%3D%200.3)
Frequency of fruit fly with genotype A2A2 will be
![q^2\\= (0.3)^2\\= 0.09](https://tex.z-dn.net/?f=q%5E2%5C%5C%3D%20%280.3%29%5E2%5C%5C%3D%200.09)
As per Hardy-Weinberg's second equation of equilibrium
![p^{2} + q^{2} + 2pq = 1\\0.49+0.09+2pq = 1\\2pq = 1-0.49-0.09\\2pq= 0.42](https://tex.z-dn.net/?f=p%5E%7B2%7D%20%2B%20q%5E%7B2%7D%20%2B%202pq%20%3D%201%5C%5C0.49%2B0.09%2B2pq%20%3D%201%5C%5C2pq%20%3D%201-0.49-0.09%5C%5C2pq%3D%200.42)
Hence, option C is correct
