The alpha helix and beta pleated sheet represent which level of protein structure?

Polypeptide chains represent the primarylevel of protein structure. The secondarystructure of a protein results from hydrogen bonding between amino acids in the peptide chain. This leads to twisting or folding of the chain into the alpha helix and the beta pleated sheet shapes.

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
