The state is thinking about building a dam. they hire a team of biologists and environmental scientists to study the impact of the dam on the local wildlife. which statement best explains how this study will be useful to the state?

the state will be able to weigh the benefits against the negative impact that the project might have in order to decide if it is safe to build the dam.

a local fishermen's club is against the project. this study will prove that there will be no impact on fish populations.

environmentalists will be opposed to the project. the study will

The statement which best explains how this study will be useful to the state is the first one - the state will be able to weigh the benefits against the negative impact that the project might have in order to decide if it is safe to build the dam.
With the help of the study, the state will decide what to do. 

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
