To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
Blood is circulated throughout the body via:
capillaries |
|
arterioles |
|
aorta |
|
veins |
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.

medulla |
|
nerves |
|
cerebellum |
|
cerebrum |

Cellular fermentation takes place:
anaerobically |
|
in the presence of oxygen |
|
in plant cells |
|
aerobically |
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.
The ovum and oviduct are part of which bodily system?
reproductive |
|
digestive |
|
nervous |
|
circulatory |
Approximately every 28 days during female ovulation an egg (ovum) is released from one of the ovaries and travels through the oviduct (fallopian tube) and into the uterus. At the same time, the endometrial lining of the uterus becomes prepared for implantation.
