Answer:
The answer is A
Explanation:
Centrioles are only found in animal cells
Well,
We need to make a Punnett square. Assuming that the man has type A, not AO or AA blood, we will have a 1 x 2 Punnett square. We just have to take the A on the left and pair it with either the A on the left column or the B on the right column.
Therefore, the percent chance of having an AA genotype is 1 in 2 or 50%, while the percent chance of having an AB genotype is 1 in 2 or 50%. Thus, the possible phenotypes are 50% A type blood and 50% AB type blood.
I have attached the resulting Punnett square.

Paramecium needs contractile vacuole due to its different environment from other protozoan that lives in salt water.
<h3>
Need of contractile vacuole for paramecium</h3>
In salt water, the solute concentration outside the cell is more than inside the cell so the water flows out of the cell down the concentration gradient. Therefore contractile vacuoles are not required for expelling water for most protozoan living in salt water.
While on the other hand, paramecium lives in fresh water so contractile vacuole is required for removing excess water so we can conclude that paramecium needs contractile vacuole due to its different environment from other protozoan that lives in salt water.
