What organelle is responsible for joining monomers to create the organic compound that is produced during translation?

All organic compounds contain covently bonded carbon.  They are made up of the monomer Amino Acids. When amino acids join to form a protein. Which is then translated. This is an organelle in the nucleus that creates ribosomes!

The correct answer would be ribosomes.

The ribosome is made up of rRNA and associated proteins.

It serves as the site of translation (formation of polypeptide chain or protein).

It has an enzymatic activity of peptidyl transferase, that is, it catalyzes the formation of peptide bonds between amino acids of growing polypeptide chain during the process of protein biosynthesis.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
