Often used to produce the product Insulin
Explanation:

<span>c.)The product only has different physical properties than the reactants because a chemical reaction occurred.
This is because rust can behave differently than oxygen and iron. This is because a chemical reaction has happened- a chemical reaction is when a new product is formed. Rust can be change chemically and physically. </span>
C is the only bad sounding thing out of this bunch.
Answer: After 3 rounds, 8 segments having 2 original strands on different segments will be present.
Explanation:
The polymerase chain reaction selectively and repeatedly copy the double stranded DNA (dsDNA) in the PCR machine.
1st round:
Single piece of double stranded DNA (dsDNA) unwinds in two seperate strands, before complementary nucleotides are synthesized to establish double helix.
2nd round:
The two dsDNA yields 4 segments before complementary nucleotides are synthesized
3rd round:
The four dsDNA yields 8 segments before complementary nucleotides are synthesized.
Therefore, at the end of 3 rounds, the two original strands will be present on the 8 different segments of copied DNA.
The water cycle is referred to as a continuous cycle because it repeats everyday. It's a cycle with no end.
