Answer:
A protease (also called a peptidase or ) is an enzyme an enzyme that catalyzes (increases the rate of) proteolysis, the breakdown of proteins into smaller polypeptides or single amino acids. They do this by cleaving the peptide bonproteins by hydrolysis, a reaction where water breaks bonds.
-5a - 12a can also be rewritten as:
-5a + -12a, which would equal -17a
1111.111 in expanded form is 1000 + 100 + 10 + 1 + 0.1 + 0.01 + 0.001
Surface area = 4πr²
⇒ 400 = 4 * 3.14 * r²
⇒ r² = 400/12.56
⇒ r² = 31.84
⇒ r = √31.84 = 5.64 inches
Answer is A.
Hope it helps!
