7)When a body cell divides through the process of mitosis, the chromosomes in the daughter cells *

10 points
are formed when chromosomes from the parent cell cross over.
are identical to the chromosomes of the parent cell.
represent only the healthiest chromosomes from the parent cell.
represent only half of the chromosomes in the parent cell.

8)Before a cell enters mitosis, what happens to the genetic information in that cell? *
10 points
The information is duplicated.
The information is selectively mutated.
The information is halved.
The information is completely changed.

9)Which of the following best describes how mitosis is related to cellular reproduction? *
10 points
Mitosis is a phase in asexual reproduction that results in the formation of similar, but not identical, nuclei in the daughter cells.
Mitosis is a phase in asexual reproduction that results in the formation of identical nuclei in the daughter cells.
Mitosis is a phase in sexual reproduction that results in the formation of similar, but not identical, nuclei in the daughter cells.
Mitosis is a phase in sexual reproduction that results in the formation of identical nuclei in the daughter cells.

10)Which of the following occurs during the interphase stage of the cell cycle? I. DNA is replicated. II. The cell divides. III. The cell grows in size. *
10 points
II only
I and III only
I, II, and III
I and II only

The cell's chromosomes separate.
The contents of the cell divide.
The cell's DNA is replicated.
The cell prepares for mitosis.

12)At a point during a cell's development, it begins to differentiate. How does differentiation occur? *
10 points
Certain genes are turned on and others are turned off; this action produces adult cells that are specialized
As a cell matures, genes that are not necessary to its function are ejected out of the cell through active transport.
The number of chromosomes in the cell is reduced by half; this action triggers the specialization of the cell.
A developing cell's function is determined by the number of organelles that are contained in the cell.
