Carbohydrates: Molecules that provide energy/ fuel and build structures in the body. Example: Sugar. Starch, Cellulose. Building Blocks. Monosaccharides
Lipids:Molecules that store energy and regulate the body's metabolic processes. Building Block: Fatty Acids and Glycerol. Examples: Fats, Steroids, Cholesterol
Proteins: Molecules that provide structural support, cell communication, storage transport, movement, and defense. Building Block: Amino Acids Examples: Enzymes, Structural Components
Nucleic Acids: Molecules that enable living organisms to reproduce genetic information and pass them from one generation to another. Building Blocks: Nucleotides. Examples: DNA and RNA Building Blocks:
Sensory neurons
Process
Light falls onto retina. The retina generates an impulse that is carried to the brain by the sensory neurons. An impulse is not carried by blood vessels, so that crosses out A. A muscle cant carry impulses either. Spinal cord isnt the answer because it doesnt have to go through the spine because the eye and brain is so close together
