Give an example for each of the four basic substances of a cell (carbogydrates, proteins, lipids, and nucleic acids)

Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products

proteins are meats.

Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others.

nucleic acids are complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
