In fermentation, what replaces oxygen in anaerobic respiration?
lactic acid or alcohol |
|
water |
|
ascorbic acid or peptides |
|
starches |
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.
An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?
Mercury and Venus |
|
Jupiter and Saturn |
|
Mars and Earth |
|
Mars and Jupiter |
The solar system also contains over a million rocky fragments of at least 1km in diameter called asteroids as well as millions more with smaller diameters. Many of these asteroids are an asteroid belt between the orbits of Mars and Jupiter.
What is the body's largest artery?
arteriole |
|
capillary |
|
aorta |
|
vena cava |
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.
Blood is circulated throughout the body via:

212°F is how many °C?
-100 |
|
0 |
|
\(135 {5 \over 9}\) |

100 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
