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).

Answer:
heterotroph and an invertebrate
Explanation:
Animals have been classified into being AUTOTROPHIC OR HETEROTROPHIC based on their nutrition while they are also classified as VERTEBRATE OR INVERTEBRATES based on their skeleton. A heterotrophic animal is one which depends on other organisms to obtain energy or food while an invertebrate is an animal that lacks a vertebrae column or backbone.
In this case, caterpillars are said to feed on many leaves before it makes a cocoon and becomes a butterfly. This means it relies on plants (leaves) for food, hence, it is HETEROTROPHIC. Also, it has an exoskeleton i.e. skeleton present outside the body. This means that it does not possess any bone inside to form the backbone, and hence it is an INVERTEBRATE.
