creating laws to protect land and wildlife
converting all public buildings to solar power
completely eliminating their dependence on fossil fuels
4
What feature of an artery makes it particularly good at keeping the blood moving forward?
The small pumps in the walls help move blood forward
Their walls are made of layers of stretchy muscle tissue
They have walls made of rigid, inflexible muscle tissue
The paddle-like valves in arteries sweep the blood forward
5

2, 1, 3, 4
3, 2, 1, 4
1, 3, 2, 4
2, 3, 1, 4
6
If a cell is damaged in such a way that it cannot stop going through mitosis, ...
A cancerous tumor will likely form.
The organism will likely grow larger.
A new, undamaged cell will likely replace it.
The damaged cell will likely be repaired.
7
What happened inside body during the stroke that leads to losing the use of his left arm?
Blood flow to a portion his brain was cut off
Aging capillaries in his left arm collapsed and shut down
A surge of blood into his brain rearranged some connections
A blood clot blocked an artery
8
compares the end result of a cell that goes through meiosis to one that goes through mitosis?
Both produce haploid cells
meiosis results in half the cells of mitosis
Both have the same number of daughter cells
meiosis results in haploid cells and mitosis in diploid
9
Which of the following structures is correctly paired with its function?
umbilical cord - circulates maternal blood through the fetus
uterus-protects fetus from harmful thingss inthe mom's blood
amniotic sac - provides an air supply for the fetus to use

12
What would be the most likely result of a man's testes getting too warm?
His testes might never produce sperm again.
His testes would produce fewer sperm.
His testes might begin to shrink.
His testes would produce extra sperm.
13
How can an athlete's body function normally with such a low heartbeat rate?
exercise makes the heart stronger to pump more blood
Athletes are born with slow heart rates it is their normal.
more capillaries appear in muscle tissue with exercise
higher than norm while exercising soit averages outto normal
