Answer:
The correct answer is "random coils".
Explanation:
Random coil is a type of polypeptide secondary structure comprised of conformation that do not follow an established conformation but rather are oriented randomly. These random coils conformations provides flexibility to proteins, since the lack of a particular structure (such as alpha helices or beta sheets), allows the protein to bend, fold or move.
The correct answer is C. Here's why:
Choice A is illogical. A single experiment does not confirm a theory as true. Multiple successful trials are needed for one to even consider a hypothesis to be accepted as a theory.
Choice B is wrong. If a scientist finds a new way to test a hypothesis, experimental methods do change. Note that when there are additional ways to test a hypothesis, a scientist should test it with additional methods.
Choice D is incorrect. If someone finds a way to test a new hypothesis, it would not be made into law since there is more information regarding the theory. This means that it would remain a theory until one can prove that it can't be tested using different methods.
