B.
Viruses are classified as biological agents instead of a living things, $& they are only made of genetic material.
Answer:
Each have adapted in very similar ways to similar habitats.
Explanation:
According to Darwin, given a similar set of conditions, two different organisms can adapt in the same direction. Here, the sugar glider inhabits Australia and the flying squirrel inhabits North America. There is a huge distance between their locations and also they are two different species with no direct evolutionary relation. However, because of the similar conditions present in their habitats, they developed same traits over the time. Both of them live in forested areas so they developed loose skin between their limbs which allowed them to glide freely between the trees.
I believe it is burning fossil fuesl
it allows scientists to determine the source of DNA recovered and use the sample from the mitochondria which has hundreds of copies unlike the two the nucleus holds and it increases the odds of recovering accurate DNA
