<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:
Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam.
The long nephron loops of the juxtamedullary nephrons are located in the renal medulla.
<u>Explanation:</u>
The kidneys are the major filtering units that are present in the body. The kidneys filter the ions of the body and expel the waste of the body and retain the required ions in the body.
The nephrons are the functional units of the kidney that are majorly responsible for the filtering action. The longer the nephron loops are more concentrated urine is expelled from the body.
