A. they prevent soil erosion
because they cover the soil (thus the name) to keep wind or water from washing away the soil.
The condition of the AIDS (Acquired Immunodeficiency
Syndrome) is caused by a virus called HIV (Human Immunodeficiency Virus). The
virus itself attacking the definite type of immune system cell inside the body.
Its cell also known as the helper cells or CD4 helper lymphocyte cells particularly
in the adaptive immune system. HIV ruining these cells, it’ll make so hard for
the body to combat off and guard off other infectious diseases. When people
gets HIV, even slight infection like fever or colds can be much critical
because the body itself has difficulty healing. Hence, immune system of one’s
person will be lowered because the helper cells are slowly being destroyed and it
makes the person unsafe.
Answer:
exposure to ultraviolet radiation is a correct answer.
Explanation:
Ultraviolet light exposure results in the formation of pyrimidine dimers. Ultraviolet radiation damage the DNA by resulting in chemical changes.
Ultraviolet radiation is absorbed by the pyrimidine bases( cytosine and thymine in DNA) and result in the formation of covalent bonds between the succeeding bases.
The formation of the pyrimidine dimers results in the distortions of DNA helix and disrupt the base-pairing during the replication of DNA which results in a mutation.
This patient has has a medial epicondylar fracture of the humerus (part of the humerus that forms the elbow joint medially). The patient was treated surgically by either open or closed reduction of the elbow. In coding this particular disease, the most appropriate code to use is CPT 24565-54-RT and 24605-54-51-RT that encompasses "<span>Fracture and/or Dislocation Procedures on the Humerus (Upper Arm) and Elbow".

Protected from the harmful effects of free radicals, often referred to as reactive oxygen species (ROS).
Hydrogen Peroxide (H2O2) is a by-product of metabolic reactions of cells that use oxygen (aerobic respiration) to produce energy from carbohydrates (food). The problem with H2O2 is that it can be toxic to cells, due to its free radical properties, as an ROS. Organisms protect themselves from this by using an enzyme called peroxidase, also known as cayalase.
