The building blocks of protein are C. AMINO ACIDS.
Amino acids are made up of a center carbon atom bound positively to a charged amino group and a negatively charged carboxyl group and a side chain.
The primary structure of a protein is the sequence of an amino acids that are attached together by a peptide bond
The secondary structure of a protein, the polypeptide is folded through the mechanisms of amino acids rotating around bonds folding into a helix or a pleated sheet structure and stabilized by a hydrogen bond.

Explanation:
<em><u>The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.</u></em>
The statement is - True.
The humans, as advanced and developed they may be, can not function and survive without the proper functioning of the biosphere, hydrosphere, atmosphere, geosphere, cryosphere. All of those spheres are crucial in defining the life conditions on our planet, and the human kind, as all other living organisms, is heavily dependent upon them.
Unfortunately, the humans have been interfering a lot in the functioning of this systems, and make it harder and harder for them to function properly, and the interfering with the ecological systems is extremely dangerous as it can have a catastrophic consequences.
Throughout the history of nursing research, most studies have focused on clinical problems. TRUE
