I think the answer must be B, although A is technically somewhat true too. Though the liver can regulate acid secretion, thus helping to balance the pH of blood by increasing or decreasing the acid secretion (can rid the body of excess acid through urine), the question doesn't specify that it balances the pH levels of BLOOD, and equally, multiple factors in the body have a role in balancing bodily pH levels, thus it is not the primary function of the liver. Thus, it must be B. The cells in the liver release an enzyme called renin, which activates angiotensin, which in turn activates the hormone aldostrene, which controls salt retention and elimination of potassium in the kidneys, thus affecting blood pressure and fluid balance.

Given data:
Hydrogen (H) = 3.730 % by mass
Carbon (C) = 44.44%
Nitrogen (N) = 51.83 %
This means that if the sample weighs 100 g then:
Mass of H = 3.730 g
Mass of C = 44.44 g
Mass of N = 51.83 g
Now, calculate the # moles of each element:
# moles of H = 3.730 g/ 1 g.mole-1 = 3.730 moles
# moles of C = 44.44/12 = 3.703 moles
# moles of N = 51.83/14 = 3.702 moles
Divide by the lowest # moles:
H = 3.730/3.702 = 1
C = 3.703/3.702 = 1
N = 3.702/3.702 = 1
Empirical Formula = HCN
So that other scientist can repeat their experiments
i hope i got i right
Answer: The density of the liquid is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of the unknown liquid = 938 grams
Volume of the unknown liquid = 
Putting in the values we get:
Thus the density of the liquid is and the liquid is dimethyl sulfoxide.
Answer:
net force is 100 N and direction is right
