Which statement describes the stem cells and how they become new types of cells?
They are embryonic stem cells that differentiate based on the expression of specific genes and the influence of external chemical signals.
They are adult stem cells that replicate based on the expression of specific genes and the influence of external chemical signals
They are embryonic stem cells that differentiate into cell types similar to their tissue of origin when their DNA mutates
They are adult stem cells that replicate into cell types similar to their tissue of origin when their DNA mutates
Select the response that best completes the sentence.

The image depicts which part of cell theory?
cells come from other cells
cells are the smallest unit of life
all organisms are made of cells
If cells missing the TP53 and cyclin proteins continue through the cycle, what will be the impact on the daughter cells produced at the end of mitosis?
The cells will be of normal size with stable DNA
The cells will be too small with stable DNA
The cell will be of normal size with mutated DNA
The cells will be too small with mutated DNA
Determine the order of stages based on the events given.
A student notes some events of the cell cycle in a list.
the nuclear envelope distinegrates
DNA is duplicated
The cell grows larger and makes more proteins
DNA condenses to form chromosomes
Growth 1, mitosis, synthesis, mitosis
Growth 1 synthesis, mitosis, mitosis
Mitosis, synthesis, growth 1, mitosis
Mitosis, growth 1, mitosis, synthesis
Bacterial cell

Using the data in the graph, when is DNA sythesized?
immediately before mitosis begins
immediately after mitosis begins
in the middle of mitosis
between the cycles of mitosis
Which checkpoint would detect an error just prior to DNA duplication in the cell cycle?
W
X
Y
Z
Which statement would be used in an argument against the use of human embryonic stem cells for therapy?
Obtaining embryonic stem cells for use in therapy requires the destruction of embryos
Embryonic stem cells are limited in their ability to become different types of cells
It is difficult to grow embryonic stem cells in laboratory cultures, so they are not a practical choice for stem cell therapy
Embryonic stem cells originate in plants, so the likelihood of rejection by a patient's body is high

A) It provides structural support to the cell.
B) It regulates the movement of substances in and out of the cell.
C) It is responsible for energy production within the cell.
D) It synthesizes proteins for the cell.
During an experiment, a student observes that a cell placed in a hypertonic solution shrinks. What is the most likely explanation for this observation?
A) Water moved into the cell, causing it to shrink.
B) Water moved out of the cell, causing it to shrink.
C) The cell absorbed solutes from the solution, causing it to shrink.
D) The cell membrane broke down, causing it to shrink.
