What is the job of tRNA a. to make our mRNA
b. to bring amino acid to the ribosome in the correct order
c. to bring the nucleus acid to the ribosome in the correct order
d. to to make more codons so translation can continue to occur

To make our mRNA

Explanation:

I think it is this one, but I am not sure, sorry if it is wrong. :(  

But I do know this, I think it might help you:

A transfer RNA (tRNA) is a special kind of RNA molecule. Its job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular "bridge" between the two. Each tRNA contains a set of three nucleotides called an anticodon.

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.
