Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.
• different from the starting cell and different from each other.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to each other.

The cells produced via meiosis are called:

• sex cells
• somatic cells
• body cells
• skin cells

If a body cell in a butterfly contains 24 chromosomes, a butterfly egg would contain

• 3
• 6
• 12
• 24

Mitosis is useful for the creation of new cells which is important for all of the following EXCEPT

• organism growth.
• repair of damage.
• replacement of worn out cells.
• generation of gametes.

After meiosis is complete how many cells will there be?

• 1
• 2
• 3
• 4

Why is sexual reproduction better than asexual reproduction?

• It gives an advantage to organisms to be different than the rest, if the environment changes.
• It is better for all organisms to be the same.
• It happens faster.
• It helps skin cells divide faster to heal wounds.
