What is the function of the circulatory system in nutrient distribution?

• Breaks down food

• Transports nutrients and oxygen to cells

• Produces enzymes

• Absorbs water

What is the main difference between monosaccharide, and polysaccharide?

• polysaccharide is made of amino acid, and monosacccharide is made of nucleotide

• polysaccharide is made of many monosaccharides

• Monosaccharide is made of many polysaccharides

• Monosaccharide is involved in structural support but polysaccharide is used as a source of energy.
