Which diagram shows cancer cells and why?

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

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

spindle fibers - help divide chromosomes

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

help the cell to divide and organize the spindle

An advantage of asexual reproduction over sexual reproduction is

all organisms survive in a stable environment

Compared to small cells, large cells have more trouble

moving needed materials in and waste products out

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

ratio of surface area to volume

What is the difference between chromatids and chromatin?

chromatin is useable, unwound DNA

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

contact with other cells stops cell growth

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