Name the phases of mitosis in order.
prophase, metaphase, anaphase, and telophase
400
Name all the phases of the cell cycle in order
Interphase, prophase, metaphase, anaphase, telophase, and cytokinesis
400
What structure starts to break down in prophase?
nuclear membrane/envelope
400
Name one difference between sexual and asexual reproduction.
You must have at least one of these answers: 1) One parent is needed for asexual reproduction, while 2 parents are needed for sexual reproduction. 2) Asexual reproduction produces genetically identical cells, while sexual reproduction produces genetically different cells

How many total chromosomes are in a human body cell like a skin cell
46 total chromosomes
500
What type of cells in the human body does mitosis divide?
It divides all body cells in the human body (like red blood cells, skin cells, hair cells) except for sperm or egg
500
Which specific phase shows the cell in the process of tearing apart into two cells?
telophase

What structure does a plant cell need when it goes through cytokinesis?
Plant cells form a cell plate to divide the cells since they have a cell wall and a fragile cell membrane, while animal cells don't need this structure to divide because their cell membrane is able to divide without a problem.
