What is the purpose of mitosis in animals?
A. to create cells with genetic variation
B. to create cells that are genetically identical

Cellular respiration occurs in both prokaryotic and eukaryotic cells. Because prokaryotes do not have mitochondria the Krebs cycle occurs in the cytoplasm. Where does the electron transport chain occur?
Cell membrane or plasma membrane
300
Which stage of meiosis is described as...
*Spindles break down
*Chromosomes condense and two nuclei form around them
Telophase 1
400
What stage of meiosis is this
Anaphase 1

Mitosis is the final stage of cellular division where the nucleus divides. In order to ensure that the correct number of chromosomes end up in each new nucleus, spindle fibers that are connected at the kinetochore of the chromosomes shorten and pull the chromatids to the sides of the cell. Which stage of mitosis does this occur in?
A. prophase
B. anaphase
C. telophase
D. metaphase
