<span>NH2-CHR-COOH is the general structural molecular
formula of an amino acid. Amino acids are known to be the building blocks of
proteins. Twenty amino acids are required to make the body's proteins. Nine of
these amino acids are called essential amino acids and they are obtained from
the food we eat or consume. The other eleven amino acids are called
non-essential amino acids that are directly synthesized by the body and may also come from different food
sources. <span>
<span>Amino
acids are composed of two functional group; the carboxylic acid group and the
amine acid group. These functional groups of atoms in a molecule have their own
characteristics during chemical reactions and are independent from the
functions of the molecule itself. </span></span></span>

Answer:
Crossing over
Explanation:
At Late Prophase I of meiosis homologous chromosomes are pair by synapsis, and lie side by side to form a bivalent.
Genetic components present in each homologue crossed to the other at the point of contacts of the arms of chromosomes(chiasmata) with each other. The arms or parts of the chromatids may break and rejoined with the other chromatids, aiding mix up. The point of the exchange of genetic material is called<u> chiasma. plura chiasmata,</u>
Therefore genetic materials from the two bivalent pair get exchanged or mixed with one another. This is called crossing over. And it forms the basis of chromosomes recombination because assuming the sister chromatids (bivalent)were from fathers and mothers, the exchange of genetic materials ensures chromosomes shuffles which gives rooms for variation
Excess fat deep within the abdomen represents a greater risk to health than excess fat else where on the body. Fat accumulated in the lower body is subcutaneous, while fat in the abdominal area is largely visceral. Where fat ends up is influenced by several factors, including heredity and hormones.
