Answer:
A star's life cycle is determined by its mass. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born.
The evolutionary selection process for glycogen metabolism<span> reflects the requirements of rendering large amounts of glucose into an osmotically stable but readily soluble </span>substrate<span> for rapid mobilization. Therefore glycogen </span>serves<span> as a glucose reserve and </span>substrate<span> buffer for local </span>energy<span> demand.</span>
Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
Physical change. Boiling water does not change the fundamental properties of the water, as it can turn back into water during condensation.
