Question text
Why must DNA condense into chromosomes during cell cycle division?
Select one:
a. Because it is very long.

Flag question
Question text
During which phase of the cell cycle do pairs of centrioles appear at the mitotic spindle?
Select one:

Flag question
Question text
What is the outcome of crossing over?
Select one:
a. Increased species diversity.
b. Decrease species diversity.
c. Mutated DNA.d. There is no outcome because the DNA that underwent crossing over is returned to its
original sequence before expression.

Question text
How does cell division differ between plant and animal cells?
Select one:
a. Plant cells must have a certain number of chloroplasts before they can divide. This is not
a requirement in animal cells.
b. In animal cells, the plasma membrane folds and encloses each nucleus to create two
diploid cells, whereas in plant cells, a new cell wall must be developed that will separate the
two cells.
c. Plant cells cannot divide, due to their rigid cell wall.
d. There is no difference in cell division between plant and animal cells.
Question 9
Correct

exact same alleles. What type of chromosomes are these?
Select one:
a. Homologous Chromosomes
b. Heterozygous Chromosomes
c. Sister Chromatids
d. Daughter Chromatids

hours.
b. A cell normally undergoes the cell cycle in 24 - 36 hours, of which mitosis occupies 1 - 2
