Answer:
<h2>c. Migration distance on a gel is inversely proportional to DNA fragment size </h2>
Explanation:
- Deoxyribonucleic acid is a genetic material that is a type of macromolecule.
- It is made up of a monomer that ais called a nucleotide. Each nucleotide is made up of a deoxyribose sugar, a base, and a phosphate group.
- Due to the presence of phosphate group DNA has negative property. When the DNA is separated by the gel electrophoresis method the size of the fragment of the DNA plays an important role.
- Those DNA fragments that are small in size migrate faster than those DNA fragments that are larger in size.
- So the migration distance is inversely proportional to the DNA fragment size.
Answer:
Vestigial structures do not have a function, yet they are homologous to functional structures in related species. They are important because they provide clues to the ancestry of the organism. Many species look similar as embryos.
The answer is <span>The release of secretin, which triggers the liver to release bile.
Secretin is the hormone released from the duodenum. It signals the secretion of bile in the liver. Bile helps digestion of lipids in the stomach.
Through the process of elimination:
- Pepsin is a hormone that breaks down proteins to the smaller peptides. So, pepsin does not breaks down lipids of high-fat meal.
- Gastrin is a hormone that triggers the gastric glands to secrete hydrochloric acid and pepsinogen, inactive form of pepsin.</span>
Hyaluronic acid, <span>also called </span>hyaluronan.
