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.

Enzymes are proteins and they control the speed of chemical reactions in your body. Without them, the reactions would happen too slowly to keep you alive.
Some break down larger molecules into smaller ones and those enzymes are in your stomach.
Chromatids are only called as chromatids when they are sister chromatids, meaning that when chromosome have two double stranded DNA attached together, each of the double stranded DNA is a sister chromatid, and while the whole thing (the two sister chromatids that are attached together) is called a chromosome.
So after the DNA has been replicated, the chromosome consist of 2 sister chromatids, attached to each other at their centromere.
Overall, sister chromatid is one of the two double stranded DNA in a replicated chromosome, and chromosome is the whole "X" shape that we see. For example, in humans, after the S phase of interphase in the cell cycle, we have 46 chromosomes, with 92 chromatids, since each chromosome is an "X" shape, by having two sister chromatids.
Hope this helps!
Answer:
200g fruit
Explanation:
fruit = 500 x 40% = 500 x 40 / 100 =
= 500 x 0.4 = 50 x 4 = 200g
