Convert -20C° to F°.
-36 |
|
78 |
|
36 |
|
-4 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(-20) + 32\)
\(F° = {-180 \over 5} + 32\)
\(F° = -36 + 32 = -4\)
Cellular fermentation takes place:
anaerobically |
|
in plant cells |
|
aerobically |
|
in the presence of oxygen |
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
Blood is circulated throughout the body via:
veins |
|
aorta |
|
capillaries |
|
arterioles |
The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.
I biome is made up of naturally occurring flora and fauna. Fauna is which of the following?
animals |
|
habitats |
|
minerals |
|
plants |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
Arteries carry __________ blood at __________ pressure.
deoxygenated, low |
|
deoxygenated, high |
|
oxygenated, low |
|
oxygenated, high |
Veins carry blood back to the heart from the body. While arteries are thick-walled because they carry oxygenated blood at high pressure, veins are comparatively thin-walled as they carry low-pressure deoxygenated blood. Like the heart, veins contain valves to prevent blood backflow.
