I have to do online research on an endangered or impacted species in my area. I chose the spotted dusky salamander. Here are the questions: 1- describe the natural environment of the species in terms of abiotic and biotic factors.

2- describe the biome in which the species lives and the properties of the biome.

3-if humans have altered the natural environment, describe the changes made by humans and their impact on the species.

4-choose from three types of scientific workers (biologists, chemists, and geographer’s) that you think could help solve the problems associated with this species, and explain how they could apply their knowledge.

C) reflection (i also looked up the other choices just to make sure)

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
