Answer:
Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.
only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.
The arms move in the Chinese breathing exercise, to the front, to the sides, and then overhead. Thus, option "C" is correct.
<h3>What is the concept of dorsal?</h3>
In the field of anatomy, the system behind the frontal plane is defined as dorsal. The dorsal region, thus, is the one that is left behind if an imaginary division of the body is done in half in a perpendicular direction, advancing perpendicular to the floor (in the case of the bipeds), or that is further from the exterior if the body is divided in half horizontally with an imaginary cut parallel to the ground (in the case of quadrupeds).
The spine, also called the spine, is the structure that develops from the pelvis to the head, via the back and neck. It protects the spinal cord, provides support to the skull and allows the human being to stay erect and move in a bipedal manner.
Thus, option "C" is correct.
