Question 14

The membrane that goes inward is separated. Each part of that membrane that separates has a nucleus and organelles

Answer 14

Animal Cell Cytokinesis

Question 15

The cell creates a cell plate that forms between the divided nuclei. As the cell plate starts to grow it separates the 2 daughter cells. After it separates the 2 daughter cells it forms a cell wall

The resting phase between the first and second division of meiosis

Answer 16

Interphase

Question 17

Interphase has 3 stages

Answer 17

G1, S, G2

The first step of interphase. This is where most of the growing of the cells occur

Answer 18

G1

Question 19

Second stage of interphase. Replicates chromosomes and new DNA is synthesized

Answer 19

S phase

Question 20

Last stage of interphase. Shortest stage. It is the growth and preparation for cell division

G2 phase

Question 21

The process of diving chromosomes during cell division in eukaryotic cells

Answer 21

Mitosis

Question 22

The process that follows mitosis is

Answer 22

Cytokinesis

Question 23

First stage of Mitosis.Chromatin condenses into chromosomes and the Nucleolus disappears. Longest phase

Answer 23

Prophase

Question 24

Second stage of mitosis. Chromosomes line up along the metaphase plate. Spindle fibers connect to the centromere of each chromosomes to the two poles of the spindle

Answer 24

Metaphase

Question 25

Third stage of mitosis. Chromosomes break at centromeres and sister chromatids move to opposite end of the cell

Answer 25

Anaphase

Question 26

The fourth stage of mitosis. Nuclear membrane reforms, nucleoli reappear, chromosomes unwind into chromatin. The end result is two new cells that are genetically identical to each other and to the parent cell
