Answer & Explanation:
a) a) Mutualistic relationship differs from parasitism because the first one benefits both of the involved organisms. Otherwise, parasitism benefits only one of the organisms and it can harm the host. Therefore, the parasite would have to be smaller than the host and it would be somehow extracting energy from the host.
b) The direction of evolutionary changes would follow some kind of pattern, like coevolution. Therefore, analyzing the phylogenies individually and then contrasting them, would help to understand how the host, as well as the parasite, have been evolving.
c) The phylogeny would also help to understand what changed first, or if they changed together as a result of coevolution.

PCR is the process of DNA duplication in vitro. We can make millions of copies of DNA in a very short period.
PCR completed in three steps; as in question these are
Step 1: Denaturation; Heat separation of strands of target DNA.
Step 2: Annealing; as complementary base pairing between primers and target DNA.
Step 3: Extension; Addition of DNA nucleotides by Taq DNA polymerase.
