Answer: D. Species C most likely diverged from Species A more recently than Species B since Species C has fewer mutations than Species B.
Explanation: The mutations between species A, B and C can be found counting the differences in the nucleotides (letters). So, the mutations in the sequences between Species A and Species B are 8, between Species A and C are 5 mutations and between Species B and C are 9 mutations. Then, we can proposed that species A and C are more close related because the sequences have fewer mutations and this could happen because they diverged more recently, compared to Species B that have more mutations.
Phospholipids all have a hydrophilic head (phosphate and specialized group in red) and a hydrophobic tail (glycerol and fatty acids in yellow).
Glycerophospholipids correspond to the combination of glycerol, two fatty acids (in yellow), a phosphoric acid and alcohols or amino acids. Alcohols or amino acids give the identity and characteristic of glycerophospholipids. Among the amino acids we find serine and among the alcohols we find inositol, ethanolamine and choline; phosphatidyl serine, phosphatidylinositol, phosphatidyl ethanolamine and phosphatidyl choline are thus obtained.
Answer:
Protease enzyme.
Explanation:
Every cell in your body has protein; for this reason, dietary protein is crucial. Proteins consist of amino acids. The cells of our small intestine cannot absorb directly large protein molecules, but they can absorb individual amino acids to build new proteins. These new proteins are needed to make new cells and to repair old cells.
The breakdown of dietary protein starts in the stomach, but the pancreas secretes protease enzymes that are needed to digest most of the proteins. Two main protease enzymes are; trypsin and chymotrypsin. They break large proteins into smaller peptides so that cells can absorb it.
Other pancreas proteases such as carboxypeptidase breaks down peptides into amino acids.
