Which of the following would be the correct mRNA sequence for the DNA of the light colored moths...

There are no options but the question can be answered based on general understanding. The mRNA sequence is:

CGU AGG CUU AGC

Explanation:

Transcription is the process by which DNA template is used to synthesize a mRNA sequence. The transcription process, which occurs in the NUCLEUS, follows the complementary base pairing rule, which states that an Adenine will always pair with Thymine (Uracil in RNA), while the Guanine will always pair with Cytosine i.e. A-U, G-C.

According to the image in this question, it shows the DNA sequences of a light and dark colored moth (mutant). The DNA sequence of the light colored moth is as follows: GCA TCC GAA TCG.

Using the priniples of complementary base pairing, the mRNA sequence of this DNA template will be: CGU AGG CUU AGC

i think that it is plants

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.
