Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts, and the second cell has very few. What would most likely characterize these cells?

A
There would be no difference between the functioning of the cells because the chloroplasts are not essential cell structures.
B
The second cell would become larger because it would have fewer chloroplasts regulating its size and shape.
C
The second cell would shrink because it would not be able to store water and maintain cell shape.
D
The second cell would not be able to produce as much food because it could not capture very much sunlight.

Which series of diagrams correctly represents the order of mitosis?

A
The steps of mitosis are shown. In step 1, the cell starts to break down structures. In step 2, the chromosomes line up at the center. In step 3, the chromatids separate from each other and are pulled to opposite ends of the cell. In step 4, the cell is divided.
