Answer:

true

Explanation:

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them.

scientific endeavor is a purely positive action that does not sometimes cause potentially harmful results.
Naya [18.7K]
I think that the question is simply asking whether the statement is correct.

The statement is wrong! The scientific endeavor (the work of the scientists, the pursue of knowledge) can be potentially harmful. For example, many tests of human medicine have to be performed on animals, and often the medicine causes great suffering in the animals (and gets rejected for testing on humans).
