Answers
1
An advantage of asexual reproduction over sexual reproduction is
organisms spend energy finding a mate
all organisms survive in a changing environment
all organisms survive in a stable environment
all organisms show a variety of traits
2
What is cell differentiation?
Skin cells turning into stem cells
Cells undergoing cell division
Cells remaining unspecialized and keep dividing
Cells becoming specialized
3
Cancer affects
Multicellular organisms only
Humans only
Multicellular and unicellular organisms
Unicellular organisms only
4
What is the difference between chromatids and chromatin?
chromatids are useable, unwound DNA
There are 4 chromatids in one chromosome
chromatin is useable, unwound DNA
chromatin is the condensed form of DNA for division
5
Which of the following explains why normal cells covering a petri dish tend to stop growing?
most cells grown in petri dishes have a defective p53 gene
the cells lack cyclin
contact with other cells stops cell growth
the petri dish inhibits cell growth
6
If cells are removed from tissue, then new cells later fill in that space, it's an example of
contact inhibition
surface area: volume ratio rule
Random cell mutations
carcinogenic exposure
7
Name the phase of mitosis shown below.
telophase
anaphase
prophase
metaphase
8
What is the correct structure & function of letter B in the diagram?
spindle fibers - help divide chromosomes
centromere - hold chromatids together
Centrioles - make spindles
chromosomes - hold DNA/genes
9
In the figure shown below, what is structure A?
Golgi apparatus
nucleus
spindle fibers
centrioles
10
Which diagram shows cancer cells and why?
B, b/c the cells are uniform
B, b/c the cells are dividing despite contact inhibition
A, b/c the cells are very large
A, b/c the cells are dividing despite contact inhibition
11
Compared to small cells, large cells have more trouble
dividing
storing needed materials and waste products
moving needed materials in and waste products out
producing daughter cells
12
Which event occurs during Interphase?
Centromeres divide
DNA duplicates
The cytoplasm divides
Spindle fibers begin to form
13
In the picture below, what role does structure A play in mitosis?
increase cell volume
replicate DNA
dissolve the nuclear envelope
help the cell to divide and organize the spindle
14
The rate at which wastes are removed by a cell partially depends on the cell's
ratio of surface area to volume
type of membrane
DNA
mutations
