Genetic variation contributes to the process of evolution by? A- Preventing extinction by allowing organisms a variety of options they can choose to inherit.

B- Preventing animals from being able to adapt to changes in their environment based on the characteristics they acquire.

C- Ensuring that a species has a higher chance of survival and reproduction by giving a species a variety of traits to successfully pass down to offspring.

D- Ensuring that a species is as homogenous as possible with little differences from one organism to another.

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

Because people are wasting it

Im not sure if you still need this but the answer is 300 hz450 hz  i just did this lesson so , wish you the best of luck and take care

Yes yes yes very good
