Claire is learning about the environmental factors, called mutagens, that can cause genetic mutations. which of the following would most likely be listed as a significant mutagen for organisms exposed regularly?

One of the environmental factors (mutagens) that can cause mutation on an organism who is exposed to it regularly is the "ultraviolet radiation" coming from the sun.

Explanation:

"Mutagens" are agents or substances that can cause genetic mutation. The "ultraviolet radiation" coming from sunlight is one of the mutagens that can cause mutation. It damages the DNA by having an abnormal connection of the "thymine dimers." This results into the kinking of the DNA shape, thus making it difficult to copy. So, the next generation cells will have a mutated copy of the DNA. This is the reason why people are always advised to put sunscreen lotions whenever they are exposed to the sun.

The other mutagens are: x-ray radiation, chemicals, nitrites and tobacco products.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
