Which of the following is an EXOGENOUS source of injury to a cell?
A fever
B bacterial toxins.
C ultraviolet radiation.
D genetic malformation

Answers

Answer 1

Answer:

C. ultraviolet radiation.

Explanation:

Cell injury occurs when cells undergo specific changes when subjected to an internal factor or an external factor. Such change causes "illness" to the person.

Under "toxic injury," two sources may cause an injury to the cell. These are endogenous and exogenous factors. Endogenous factors originate within the body while the exogenous factors originate from the environment.

Among the choices above, it is only the ultraviolet radiation that is considered an exogenous factor because it originates from outside the person's body. Prolonged exposure to UV light damages the cells which can lead to cancer.

Which signs might a teacher look for in a student who is experiencing stress? Check all that apply

Answers

Answer:

what are the options?

Explanation:


In the United States, the onset of puberty has been occurring earlier and earlier. Today, about 10 percent of children ages 6 or 7 begin developing signs of puberty, a condition known as precocious puberty.

In the early 1900s, girls typically began menstruating at age 17. Today, girls typically begin around age 12. This trend has been attributed to the growing number of overweight children and a greater exposure to pollutants. Exposure to phthalates, artificial chemicals found in plastics, has also been cited as a cause. These chemicals disrupt the endocrine system by mimicking hormones in the body.

Early puberty can have many negative side effects, including an increased risk of certain types of cancer, such as breast cancer. Children are often emotionally unprepared for the physical changes taking place in their bodies. As a result, behavioral and psychological problems may increase.
