Answer:
A. True
Explanation:
Carboxypeptidases are enzymes which function in the digestion of short peptides known as oligopeptides in the small intestine. Oligopeptides contain between 10 to 50 amino acid residues.
The two carboxypeptidases A and B involved in the digestion of proteins in the small intestine are secreted by the exocrine glands of the pancreas.They are both zinc-containing enzymes which remove successive carboxyl-terminal (C-terminal) residues from oligopeptides until free amino acids are obtained.
Since they function in this way, they can be used to determine the entire sequence of short peptides or oligopeptides.
Answer:
1.44L
Explanation:
P1V1/T1=P2V2/T2
since the temperature didn’t change, stay at 20celsius, we can ignore T1 and T2.T1=T2
(1.00atm)(3.60L)=(2.50 atm)V2
V2=(1.00atm)(3.60L)/(2.50atm)
=1.44L
This example is an controversial matter because melting an candle is considered as both physical change and chemical change because no new substances were made by melting an candle. The final answer is C.

Answer: I. The number of molecules is conserved.
III. Atoms are neither created nor destroyed
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
For example: 
Thus in the reactants, there are 4 atoms of hydrogen , 2 atoms of oxygen and 2 atoms of sodium.Thus there will be 4 atoms of hydrogen, 2 atoms of oxygen and 2 atoms of sodium in the product as well.
