A) a visible contractile ring
B) two separate cells
C) elongated, noncondensed chromosomes that are difficult to visualize

43) A cell is observed under the microscope. What feature will indicate that it is in anaphase?

44) If a cell with 16 chromosomes undergoes mitosis, how many chromosomes will each daughter cell have?
A) 8
B) 4
C) 32
D) 16
45) What would happen if the cell cycle proceeded normally except cytokinesis did not occur?
A) The absence of cytokinesis would inhibit mitosis.
B) The G1 and G2 phases would become shorter.
C) Cells without nuclei would be formed.
D) A large cell with multiple nuclei would result.
46) While looking under a microscope, you see two neighboring daughter cells. One of the cells contains three chromosomes, and the other contains five. The parent cell normally contains four chromosomes. What could be the reason for the different number of chromosomes in the cells?
A) The division of sister chromatids of one chromosome did not occur properly during mitosis.
B) The nuclear envelope did not dissolve, so mitosis could not occur at all.
C) Replication of DNA did not occur properly.
D) The division of homologous chromosomes during meiosis II did not occur properly.
47) Chromosomes uncoil and new nuclei form during:
A) prophase.
B) metaphase.
C) anaphase.
D) telophase.
48) How do daughter cells at the end of mitosis and cytokinesis compare with the parent cell before DNA replication occurs?
A) The daughter cells may have the same number of chromosomes but double the amount of DNA.
B) The daughter cells have the same number of chromosomes and the same amount of DNA.
C) The daughter cells have half the number of chromosomes and half the amount of DNA.
D) The daughter cells have half the amount of cytoplasm and half the number of chromosomes.
49) Why is prokaryotic cell division fundamentally different from eukaryotic cell division?
A) Prokaryotic cells divide for several months and then live for decades without dividing.
B) Prokaryotic cells do not have a plasma membrane.
C) Prokaryotes have many more chromosomes to divide.
D) Prokaryotic cells have a single chromosome and no nuclear membrane.
50) What is one of the differences between cell division in plant cells and cell division in animal cells?
A) Plant cells separate chromosomes by attachment to the plasma membrane.
B) There is no DNA replication before cell division in plant cells.
C) Plant cells do not use a mitotic spindle to separate chromosomes.
D) Plant cells separate by the formation of a new plasma membrane and cell wall in the middle of the cell.
