Answer:
Option C
Explanation:
Image for the question is attached here
Solution
It is given that the membrane is permeable to both salt and water.
Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.
As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.
Thus water will move from side A to side B and Salt will move from side B to side A.
Hence, option C is correct
Answer:
0.8
Explanation:
Allele frequency simply shows how common an allele is in a population.
It is calculated by counting the number of times it appears divided by the total number of copies of the gene.
The frequency of all alleles of a gene present in a population must equate to 1.
so,<u><em> p+q=1</em></u>
If the Allele frequency of A whose phenotype are green grasshoppers is 0.2 to find the frequency for a (brown grasshoppers) will be';
<u><em> 1-0.2=0.8</em></u>
