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).

because A detritivore (also known as decomposers) is an animal that feeds on dead organisms(living things) and breaks them down into smaller molecules. Detritivores are essential in the ecosystem as they return important materials such as carbon (see carbon cycle) back into the environment. Examples of common detritivores include earthworms and woodlice, but also includes microscopic (things that can only be seen using a microscope) bacteria.

8. Explain how the body is able to increase its oxygen intake during exercise. ​
Ne4ueva [31]

Explanation:

While exercising, the muscles need additional energy as the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. The heart rate increases to supply the muscles with extra oxygen and remove the carbon dioxide produced.
