|
-23 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
Which of these digestive enzymes is not produced by the pancreas?
trypsin |
|
gastric acid |
|
pancreatic amylase |
|
lipase |
The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.

heating |
|
sublimation |

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.
The heart __________ blood.
filters |
|
oxygenates |
|
deoxygenates |
|
creates |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
