During the S phase, there is duplication of chromatids thus
considering it a single chromosome thus there is no change in
number of chromosomes. Only dna content gets doubled.
If the S phase of interphase occurred but G1 and G2 did not,
would the cell still undergo cell division?A)Even though G1 and G2
phases did not occur and therefore protein synthesis did not occur
in interphase, the cell would still divide. The enzymes, proteins
and chemical messengers will be made in prophase to conduct the
cell division process B)No, the cell would not divide since G1 and
G2 did not occur and therefore the proteins, enzymes and chemical
messengers...
Consider an animal cell that has eight chromosomes (four pairs
of homologous chromosomes) in G2 phase. Match how many
of each of the following features the cell will have at mitotic
prophase :
A. sister chromatids
B. centromeres
C. kinetochores
D. centrosomes
E.
centrioles
A researcher conducted an ANOVA (alpha = .05) between 4 groups
(G1, G2, G3, G4), with 11 people in each group. The MSBetween was
5.62 and the MSWithin was 2, leading to an F test statistic of
2.81.
Answer the following:
1) What were the hypotheses in statistical notation (2
points)?
2) What is the critical value (1 point)?
3) Make a decision regarding whether to reject H0 and what that
means with regard to the group means (3 points)....
So, I'm confused with the S-phase in interphase. Would the
number of chromosomes double in number during the S-phase? Wouldn't
there be 23 pairs of chromosomes (46 total) before Sphase and 43
pairs (92 chromosomes) after S-phase? Or am I confusing them with
the number of chromatids? How many chromosomes would there be
during Anaphase I of meiosis, and Telephase II of meiosis (before
cytokenesis)?
Ploidy does not change during meiosis, ploidy halves
during mitosis
True
False
The number of chromosomes in a cell is referred to as
ploidy
True
False
DNA is not replicated between meiosis I and
II
True
False
Homologous chromosomes contain the same genes but
different specific DNA sequences
True
False

Why does the chemical potential change with pressure even if the
system is incompressible (that is, remains at the same volume when
pressure is applied)?
Which phase do the chromosomes duplicate?
Which phase does the cell spend most of its lifetime and
approximately how long?
What is the mitotic spindle?
What is a centriole and what is its function?
Centrioles are located inside what?
Where does the mitotic spindle grow out of?
Duplicate chromosomes and duplicated centrosomes would mark the
end of what?
What is the relationship between the number of chromosomes in an
organism's genome and its biological complexity?
a) more complex organisms have a higher number of chromosomes
due to a higher number of genes
b) organisms have the same number of chromosomes, even though
they vary in complexity
c) there is no relationship, many less complex organisms have a
large number of chromosomes
d) less complex organisms have fewer chromosomes because it
takes less time and energy to replicate their...
Investigate the difference between "phase velocity" and "group
velocity." Why does an index of refraction of less than 1 (so
v>c) not violate relativity, which says no information can move
faster than the speed of light?
Why does the substantial correlation between one year’s stock
price change and the change in next year’s corporate earnings
support the idea that stock prices change to reflect expectations
about the future?
