Answer:
The correct answer is C. An oxygen
Explanation:
Amino acid is a compound which serves as the building block or proteins. They are the smallest and simplest unit of protein. They contain carbon, oxygen, hydrogen, and oxygen.
Each amino acid has a central carbon atom which is designated as alpha carbon which is attached with a carbonyl functional group, an amino-functional group, a hydrogen atom, and a side chain(R group). So oxygen is not bound directly with the central carbon atom.
The R group is different in different amino acid. Glycine is the simplest amino acid and it has H in place of the R group.
I assume the second option because the half sun half shade situation would provide the nutrients for the plants and at the same time nit half too much( since some plants need indirect sunlight and this is a good compromise) also glass is typically used in greenhouses and therefore would be my container of choice and fertilizer will assist in plant growth
