c period of prehistory
d industrial revolution

B. During the agricultural revolution, there were vital new improvements in farming techniques that made a sharp increase in human population.

Explanation:

The agricultural revolution began in Great Britain between the mid-17th century and the late 19th century. It brought new crops and grains and also new methods of farming and agriculture. Good irrigation system and drainage facilities also helped to increase the productivity of the crops.

An immense increment in farming output and productivity during the agricultural revolution added to the growth of the population. The farming revolution made a surplus of nourishment, so fewer people started to die of starvation. Statistics demonstrate that the revolution of agriculture committed a global rise in population.

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
