question 8 of 10
how is a scientific theory developed?
a. an experiment is repeated over and over with the same results.
b. a single experiment is carefully performed once.
c. many different experiments are repeated many times.
d. one scientist supports his or her hypothesis with an experiment.

Explanation:

A scientific theory is developed when many different experiments (conducted by multiple scientists over time) are repeated many times. This repetition and consistency across various experiments (not just one experiment repeated or a single - experiment - once) help in validating the underlying concepts. A single scientist's experiment (even if it supports a hypothesis) is not sufficient for a theory.

Answer:

C. Many different experiments are repeated many times.
