Is one codon that will start the process of protein synthesis. a) aga b) aug c) uga d) ugu

B   AUG

Explanation:   The start codon is AUG. Once this codon is detected, the cell knows that this is when to start putting the amino acids together to make the protein.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
