Question

The idea that all living things are made up of cells is considered scientific law. This means the idea
A) is an emerging scientific idea that has a logical explanation.
B) has been tested with similar results at least twice.
C) is supported by scientific consensus and a large amount of evidence.
D) has been rejected only once by the scientific community.

Answer 1

C

Answer 2

C

Answer 3

You can eliminate A; It's certainly not 'emerging'.
B is the definition for a tentative theory, not a law.
The 'cell theory' has been rejected in its fledgling stages, but other 'laws,' eg Newton's laws, were not. Therefore D can be eliminated.

That leaves us with C as the answer. Just to check, has the law of cells been supported by a large body of evidence? Have you ever looked down a microscope at something living? I'm guessing you have. Then yes, there is evidence.

Thus C.
