(1 point)
Responses

They can use those pieces to reconstruct the organism.
They can use those pieces to reconstruct the organism.

It isn’t important. Those pieces are not very useful.
It isn’t important. Those pieces are not very useful.

Those pieces hold DNA, which the scientists can use to identify the animals.

Answer 1

The correct response is:

Those pieces hold DNA, which the scientists can use to identify the animals.

Answer 2

Why did Elizabeth Clare and her team use a group of naked mole rats that had been in one room for many generations in their study?(1 point)
Responses

The DNA would have built up in the air during the time they had been there.
The DNA would have built up in the air during the time they had been there.

The DNA would have spread out and been more difficult to obtain.
The DNA would have spread out and been more difficult to obtain.

Naked mole rats are special because they do not have DNA.

Answer 3

The correct response is:

The DNA would have built up in the air during the time they had been there.
