Answer:
intracellular metabolism, replication, and exposure to genotoxic agents, suck as ionizing radiation.
Proteins are the polymer of amino acids.
<h3>How protein is formed?</h3>
Proteins are the polymer of amino acids which means that large number of amino acid combines to form protein molecule. The function of protein is to make muscle cells inside the body. The bonds present in protein are peptide bonds.
Proteins made up the structure of many enzymes or in other words, Enzymes are proteins that are comprised of amino acids which are linked together in one or more polypeptide chains.
So we can conclude that Proteins are the polymer of amino acids.

Answer:
A) areolar tissue soaks up excess fluid in an inflamed area
Explanation:
Areolar tissue is found around blood vessels, muscles, nerve bundles. Edema which is also a part of inflammation occurs when blood capillaries of blood vessels leak the fluid and is soaked by areolar tissue. So excess fluid in these tissue cause swelling of that part.
Edema is one type of defense reaction to the cell injury. With fluid white blood cells and defense proteins move in the area and counter the infectious agent of injury and helps in eliminating the injurious factor. So the correct answer is A.

Crossing-over is when homologous* chromosomes exchange genes. This result in different gene combinations.
-------
<em>*A pair of matching chromosomes. They have the same genes but can have different versions. </em>
