Question

A group of students was designing an experiment to test the effect of smoking on grass frogs. They hypothesized that keeping the frogs in a smoke-filled environment for defined periods would result in the animals developing lung cancer. However, when they searched for previously published information to shore up their hypothesis, they discovered they were quite wrong in their original assessment. Even though they were never going to go ahead with their experiment (so as not to harm frogs needlessly), they knew that a more likely outcome of putting carcinogens in the air would be the development of ___.

a. diminished absorption of oxygen
b. tracheal tube abnormalities
c. skin cancer.
d. the amphibian equivalent of hypertension.
e. gill abnormalities in the next generation of tadpoles

Answer 1

the answer to this question is C. Skin cancer

Step-by-step explanation:

A more likely outcome of putting carcinogens in the air would be the development of skin cancer

Carcinogens may increase the risk of cancer by altering cellular metabolism or damaging DNA directly in cells, which interferes with biological processes, and induces the uncontrolled, malignant division, ultimately leading to the formation of tumors.

Hence the answer is C.
