Tadpoles raised in water with atrazine levels of 0.1 ppb should produce a higher percentage of male frogs with gonadal abnormalities than those raised in pure water.
this statement is an example of:

a. a question leading to a hypothesis
b. a hypothesis
c. a testable prediction leading to design of an experiment
d. data from an experiment
e. an interpretation of data

Option C, a testable prediction leading to design of an experiment

Explanation:

The statement here predicts the outcomes of raising tadpoples is water with atrazine levels of 0.1 ppb as compared to the ones raised in pure water. Hence, it cannot be question. Now since this prediction can be tested, an experiment can be designed where a certain number of tadpoles can be raised in pure water and the same number of tadpoles can be raised in water with 0.1ppb of atrazine level. The difference in two populations can be then compared to either support the prediction or contradict it.

Hence, option C is correct

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
