Answer:
C. Larger compounds break down into two or more smaller compounds.
Explanation:
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.

Answer:
Tertiary.
Explanation:
Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.
Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.

<span>The answer is letter B.
Almost
all chemical reactions in life processes occur in solutions with water. It
is
the most abundant molecule found in living organisms. Most mammals, in fact,
are approximately 70% water by weight. About 2/3 of this water is present inside cells. The other 1/3 is present
outside cells (e.g in blood plasma or other body fluids).Without water the
proper transport and processes that occur with a cell will not efficiently
function therefore making the organism inefficient as well. <span> </span></span>
