Answer:

d. secondary structure ... hydrogen bonds

Explanation:

The secondary structure of a polypeptide corresponds to localized regions of orderly structure stabilized by hydrogen bonds between the backbone groups -NH and C = O and in which no hydrogen bonds involving the side chains participate. The secondary structure of the polypeptide is characterized by its ability to curl or fold, the folds being maintained by the polypeptide chains.

Ludmilka [50]

Answer:

c. Ribosomes

Explanation:

Ribosomes can be found in eukaryotic and prokaryotic cells.  In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm.  In both cells, ribosomes intertwine into an RNA molecule and form polysomes.

Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.
