Answer:
c)polymerase chain reaction (PCR).
Explanation:
Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).
The membrane of an organelle or cell is comprised of proteins circulating in a phospholipid bilayer.
The proteins in membranes are the ones which can facilitate chemical reactions.

Researchers accept proposing speculations that negate current hypotheses. So, the proper alternative is D i.e., Scientists with varied experimental processes and interests perceive things differently.
As of late, the structure of molecules has been found. Sometime recently the perfect demonstration of a molecule was found, and a few others were proposed and abandoned.
In J.J. Thomson's theory, Thomson compared the definition of an iota to that of a Christmas pudding. He claimed that atoms are made up of an emphatically charged circle with inserted electrons.
Additionally, he claimed that since the sizes of positive and negative charges break even, an iota as an entirety is electrically impartial.
Rutherford tested with α-particle diffusing on a gold sheet. He took note that the lion's share of the negative particles did not divert when they voyage through the gold foil.
