In the picture below, what role does structure A play in mitosis?

help the cell to divide and organize the spindle

Compared to small cells, large cells have more trouble

moving needed materials in and waste products out

What is the correct structure & function of letter B in the diagram?

spindle fibers - help divide chromosomes

What is the difference between chromatids and chromatin?

chromatin is useable, unwound DNA

Which diagram shows cancer cells and why?

A, b/c the cells are dividing despite contact inhibition

An advantage of asexual reproduction over sexual reproduction is

all organisms survive in a stable environment

Which of the following explains why normal cells covering a petri dish tend to stop growing?

contact with other cells stops cell growth

The rate at which wastes are removed by a cell partially depends on the cell's

ratio of surface area to volume

Answers

1
In the picture below, what role does structure A play in mitosis?
dissolve the nuclear envelope
increase cell volume
replicate DNA
help the cell to divide and organize the spindle
2
If cells are removed from tissue, then new cells later fill in that space, it's an example of
contact inhibition
Random cell mutations
carcinogenic exposure
surface area: volume ratio rule
3
Compared to small cells, large cells have more trouble
storing needed materials and waste products
dividing
moving needed materials in and waste products out
producing daughter cells
4
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
5
What is the difference between chromatids and chromatin?
chromatin is the condensed form of DNA for division
chromatin is useable, unwound DNA
chromatids are useable, unwound DNA
There are 4 chromatids in one chromosome
6
Name the phase of mitosis shown below.
telophase
metaphase
anaphase
prophase
7
Which event occurs during Interphase?
DNA duplicates
Centromeres divide
The cytoplasm divides
Spindle fibers begin to form
8
What is cell differentiation?
Cells undergoing cell division
Cells remaining unspecialized and keep dividing
Cells becoming specialized
Skin cells turning into stem cells
9
Which diagram shows cancer cells and why?
A, b/c the cells are very large
B, b/c the cells are uniform
A, b/c the cells are dividing despite contact inhibition
B, b/c the cells are dividing despite contact inhibition
10
An advantage of asexual reproduction over sexual reproduction is
all organisms survive in a changing environment
all organisms show a variety of traits
organisms spend energy finding a mate
all organisms survive in a stable environment
11
Which of the following explains why normal cells covering a petri dish tend to stop growing?
contact with other cells stops cell growth
the cells lack cyclin
the petri dish inhibits cell growth
most cells grown in petri dishes have a defective p53 gene
12
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
mutations
DNA
13
In the figure shown below, what is structure A?
spindle fibers
Golgi apparatus
nucleus
centrioles
14
Embryonic stem cells have the potential to do which of the following?
Produce nerve cells/neurons to help a person w/ paralysis
All of the above
treat diseases like diabetes and Parkinson's
Repair damaged organs like livers and hearts
15
Cancer affects
Humans only
Unicellular organisms only
Multicellular organisms only
Multicellular and unicellular organisms
