Question 10
Amylase is an enzyme that breaks down starch. You should know that enzymes function the BEST at 35 deg C and if the temp is above or below that level they will denature.
The answer, therefore, is C.
Question 14

Therefore, it wouldnt flow as a constant stream. Since it flows under high pressure (it is synchronized with the heart beat) the blood WILL NOT clot.
Answer = C
Question 40
