What do proteins carbohydrates and lipids have in common

C. They are all formed from the same elements.

Explanation:

Proteins, carbohydrates, and lipids are the biomolecules found in cells of living beings. Proteins are polymers of amino acids which have one central carbon atom to which amino group (NH3), carboxyl group (COOH), a hydrogen atom (H) and one side chain are bonded.  

Carbohydrates are the chemicals that also have C, H, and O in their structures.

Lipids are the derivatives of fatty acids which in turn are derived from hydrocarbons.

Hence, protein, carbohydrates, and lipids are formed of some common elements namely, C, H, and O.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
