NACL is the correct answer
Provides protection and support
For example, first, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
Hope this helps! :D
The answer to this is most certainly not A or C, so you can rule those out. If you look at DNA, every persons has different nitrogenous bases (<span>adenine (A),guanine (G), thymine (T), and cytosine (C))
This means the answer to your questions is #2, DNA.

Answer:
Energy retained at consumer level 1 - 100 units
Energy retained at consumer level 2 - 10 units
Energy retained at consumer level 3 - 1 units
Explanation:
The total units of energy lies at the producer level of the energy pyramid.
Now at each trophic level only 10% of the energy of its previous level is passed on which means at
Consumer level 1 -
energy retained % energy at producer level
units
Like wise -
Energy retained at consumer level 2 -
units
Energy retained at consumer level 3 -
units
Thus,
Energy retained at consumer level 1 - units
Energy retained at consumer level 2 - units
Energy retained at consumer level 3 - units
