Question 7

Question 8

Answer 8

in the nucleus, chromosomes condense and become visible. In the cytoplasm, the spindle forms.

Question 9

prometa-phase

Answer 9

the nuclear membrane breaks apart, and the spindle starts to interact with the chromosomes.

Question 10

Metaphase

Answer 10

the copied chromosomes align in the middle of the spindle

Question 11

anaphase

Answer 11

chromosomes separate into two genetically identicle groups and move to opposite ends of the spindle.

Question 12

telephase

Answer 12

nuclear membranes from around each two of the chromosomes, the chromosomes begin to spread out and the spindle begins to break down
