Answer:
The correct answer is - contractile vacuoles: osmoregulation by contraction and expansion,
other vacuoles: storage of nutrients, water, and waste also help in maintaining shape.
Explanation:
Contractile vacuoles are the characteristic features of the protozoan, unicellular algae that helps in expelling water by the process of osmoregulation by expansion and contraction.
Other vacuoles are primarily the storage unit of the cell as they store excess nutrition, waste or water in it. It also helps in maintaining the shape of the cells.
Thus, the correct answer is - contractile vacuoles: osmoregulation by contraction and expansion,
other vacuoles: storage of nutrients, water, and waste also help in maintaining shape.

Step 1: Figure out genotypes of parents
Jessica's mom: I^A I^B
Jessica's dad: ii
Step 2: Punnett Square:
( i ) ( i )
(I^A) I^Ai I^Ai
(I^B) I^Bi I^Bi
Step 3: List possible phenotypes
Jessica could be either blood type A (I^Ai) or blood type B (I^Bi)
