32
is interphase part of mitosis
no
33
is cytokinesis part of mitosis
no
34
what are the two main things you need to know about the g1 phase
intense growth centrioles duplicate
35
What is the most important hting that happens in s phase
DNA is duplicated
36
What happens in G2
prepares for mitosis
37
What is the longest phase of the cell cycel
interphase
38
A body cell with 14 chromosomes goes into g1 phase. How many chromosomes does this body cell have as it enters mitosis?
28
39
What is special about prophase
it is the longest phase
40
can we see chromosomes in prophase
yes
41
duplicate strands attach at the center of what phase?
Metaphase
42
The centrioles begin to move to opposite poles and the spindle (microtubules) connect between them in what phase
pro phase
43
What's special about metaphase
the chromosomes line up in the middle and the chromatid attach at the centromere
44
what helps the sister chromatids separate at the centromere
spindle
45
What's special about telophase?
this is when the chroosomes unwind and are no longer visibile
46
what phase do chromosomes show
prophase metaphase and anaphase
47
As a cell becomes larger, the _____ increases Faster than the_____
volume cells surface area
48
The larger the cell becomes there is a greater demand on _____
the DNA
49
How do cells solve the problem of getting too big
cell division because the cell divides into two daughter cells.
50
Why does the cell copy all DNA
so each cell has the exact same amount of original DNA.
51
The cell splits in half solving the _____ and _____ problem.
surface area and volume
52
Sexual reproduction provides genetic diversity for _____
the continuation of species
53
is the offspring is genetically identical to the single parent in asexual or sexual reproduction
asexual
54
There is no exchange of DNA information so no genetic diversity in asexual or sexual reproduction
asexual
55
Why is there no genetic diversity in asexual reproduction?
there is no exhange of DNA
56
_____ reproduction is reproduction with the fusion of reproductive cells
sexual
57
Sexual reproduction is reproduction with the _____
fusion of reproductive cells
58
In sexual reproduction Offspring inherit how much of their information from each parent
half
59
in _____ reproduction offspring inherit half of their information from each parent
sexual
60
