Groundwater is the source of drinking water for more than one-half of U. S. residents. As water seeps through the soil, it carries
substances applied to the land, such as fertilizers and pesticides. Water moves through aquifers, and eventually surfaces in
discharge areas, such as streams, lakes, and estuaries. It is common to think of surface water and groundwater as separate
resources but they are interconnected. Imagine your source of household water is groundwater and you want that water to be free
from contaminants and toxins. Using the illustration above, choose all the possible sources of contamination to your water.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
