<h2>Answer:</h2><h2>Part 1.</h2>
The correct option of 38 question is B which is be the smaller size.
<h3>Explanation:</h3>
As the cell is suspended in salt solution which is hyper tonic as compared to cell.
And salt ions are also not allowed to enter the cell, so the consequence will be the movement of water from cell to salt solution to make cell equal to salt solution.
So the cell will shrink making cell of smaller size.
<h2>Part 2.</h2>
The correct option of 39 question is option B which is cell B will swell more than cell A.
<h3>Explanation:</h3>
- Actually here swelling means the size of cells.
- At the end the size of cell B will be more than the size of cell A. Because the cell A is placed in less concentrated solution than the cell B.
- First glucose will diffuse to cell making cell hypotonic and after that water moves in cell by osmosis.
- Water always move from high concentration to low concentration.
- As in cell A low amount of glucose and water will move in cell than Cell B.
- Hence Cell b will swell more than A.

Answer:
The genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2.
Explanation:
In the example given in the question, the color of the petals of snapdragon flowers are given with the An1 allele having full activity and the An2 allele being the null allele. For the F1 offspring, two snapdragon flowers are crossed, one with red petals which is An1An1 and one with ivory petals which is An2An2. All the genotypes for the F1 offspring will result in An1An2.
Then using this F1 offspring, the F2 offspring is found and the genotype of the F2 offspring will be An1An1 / An1An2 / An1An2 / An2An2.
So the genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2. One red petal snapdragon, 1 ivory snapdragon and 2 pink snapdragons.
I hope this answer helps.
