Question 2

slide 1- zygote

where did the masses come from?

Answer 2

the nucleus of the egg; the sperm that fertilized the egg

Question 3

2 / 4

Question 9

slide 7- telophase

are the two chromosome groups separated or apart?

Answer 9

completely separated

Question 10

slide 7- telophase

what is happening to the cell membrane?

Answer 10

the cell membrane pinches inward, dividing the cytoplasm into two masses
