In studying a transporter, it is found that no external energy input is needed to facilitate the movement of a neutral compound through the transporter. The translocation rate of the compound reaches a plateau at high levels of compound. It is a(n)

passive transport carrier.

Explanation:

Passive transport carrier is a term that describes the movement of substances across the cell membranes in the body without requiring any form of cellular energy.

This movement is based on the permeability level of the cell membrane and it moves from higher concentration to lower concentration level.

Hence, in this case, the correct answer is PASSIVE TRANSPORT CARRIER.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
