the eggs and larvae of marine animals tend to require water with more dissolved oxygen in it than the adults do. if water flows from a freshwater source into a salt water bay, what effect would this have on the population of marine animals? (2 points)

select one:

a. the freshwater would decrease the populations of marine animals because it would deplete the salt water of oxygen.

b. the freshwater would decrease the populations of marine animals by decreasing both salinity and oxygen levels.

c. the nutrient-rich freshwater would encourage algal blooms, thereby increasing the levels of oxygen and marine animals. (incorrect)

d. the freshwater would increase the populations of marine animals because it holds more oxygen than the salt water.

The right answer is c.sandstone.

D. peatlands,grassland,swamps

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
