Answer 3

Interphase

Question 4

structure in the nucleus that contains hereditary material

Answer 4

Chromosome

Question 5

Answer 5

Chromosomes

Question 6

Answer 7

Nuclei

Question 8

Nucleous and ____________ disintegrate

Answer 8

Nuclear membrane

Question 9

move to oppisite ends of the cell

Answer 9

Centrioles

Question 10

begin to stretch across the cell

Answer 10

Spindle fibers

Question 11

pairs of chromatids line up across the center of the cell.

Answer 11

Metaphase

Question 12

Anaphase

Answer 12

• each centromere divides

- each pair of chromatids separates and moves to opposite ends of the cell.

Question 13

Telophase

Answer 13

Spindle fibers disappear and a new nucleus forms.

Question 14

Results of Mitosis

Answer 14

• Each cell in your body except sex cells has the same number of 46 chromosomes
• Allows growth and replaces worn out or damaged cells
