I would have to say that A is the correct answer.
A (Aganine) , T (Thymine), G (guanine), C (cytosine).
Below are the choices:
(1) a nucleus
<span>(2) a chromosome </span>
<span>(3) a protein molecule </span>
<span>(4) an enzyme molecule
</span>
In the nucleus. However since chromosomes are in the Nucleus they contain the <span>DNA a cell needs to survive. This is why it is in the Nucleus.

Answer:
<em>The correct option is D) Y, X, Z</em>
Explanation:
The similarities in the amino acid sequence might predict that the organisms which share the most similar sequence are more closely related to one another.
As we can see the sequence Y, Q-Q-Q-N-N-S-C-C- is shares the most similarities with the given amino acid sequence of an enzyme from a worm, hence it is the most similar. The sequence X, -Q-R-Q-N-S-S-C-C-, shares more similarities with the amino acid sequence of the worm hence it is more closely related as compared to the sequence mentioned in option Z which is -Q-Q-R-N-S-N-C-C- .
<span>Natural gas tends to be contained within the underground rock itself. The rock must be broken to release the gas. And if it’s brought out the wrong way, it can contaminate the groundwater supply surrounding it. To get the most gas possible, after drilling a hole, energy companies line the hole with materials meant to keep the gas in. Next, they send electric charges down the well, which affect the rock around it. After the charges are set off, a highly-pressurized liquid fracking solution is sent down the well. This solution breaks up the rocks, releasing the natural gas. Since the gas is lighter than the fracking solution, it rises to the top of the well for capture.</span>
