A molecule that moves across a cell membrane without using the cell’s energy tends to move A. away from the area of equilibrium.
DENIUS [597]

Answer:

C. away from the area where it is more concentrated.

Explanation:

If a molecule is moving across a cell membrane w/o using the cell's energy, it is diffusion, which is defined as the movement of a substance from higher to lower concentration. Diffusion <em>never </em>requires energy, whether it is facilitated or not, as clustered molecules and/or atoms simply want to get the heck away from each other if in too high concentration in a single place. The type of molecular movement across a cell membrane that would require the cell's energy would be active transport, which often requires ATP or GTP and works against a concentration gradient.

Cheers.

Studentka2010 [4]

The messenger RNA (mRNA) is not found here but it is possible to find the correct amino acid sequence by using the genetic code.

<h3>What is the genetic code?</h3>

The genetic code can be defined as a series of instructions to convert a DNA sequence to a protein sequence.

The mRNA is composed of triplets of nucleotides called codons that specify different amino acids during translation.

In conclusion, the mRNA sequence is not found here but it is possible to find the correct amino acid sequence by using the genetic code.
