Can someone help me please asap

Molecule 3

Explanation:

DNA contains Deoxyribose, Phosphate, and 4 bases: Adenine(A), Thymine(T), Guanine(G), and Cytosine(C)

Molecule three contains Deoxyribose, Phosphate, and Guanine, while the others do not.

RNA contains ribose, which is why Molecule 2 is out of the question.

DNA does not contain glucose, henceforth marking Molecule 1 incorrect.

Molecule 4 may seem correct, but recall that DNA contains Deoxyribose, Phosphate, and a base, in this case Guanine(G). This answer contains no Deoxyribose.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
