Overfishing has depleted the rich harvests of fish from the oceans. As a solution, a large industry that cultivates shrimp and fish in warm coastal ponds has been developed. To make way for these ponds, mangrove
forests are cut down. Local organisms are displaced. In order for people to decide if this new fish farming
technology is a good long-term solution, they must consider
(1) the risks and costs as well as the benefits
(2) that the mangrove forests would probably die off someday anyway
(3) that food production is always more important than any other concern
(4) the number of fish produced in the first year as compared with ocean fishing

I’m going to go with b!

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
