Carbohydrates may form larger carbon-based macromolecules by combining with which elements? a. sodium, potassium, nitrogen b. nitrogen, sulfur, phosphorus c. potassium, sodium, sulfur d. silicon, phosphorus, sodium

Answer;

B.nitrogen, sulfur, phosphorus

Explanation;

-Single units of carbohydrates called monosaccharides may undergo various reactions to form carbohydrate derivatives. Derivatives in case of carbohydrates often means modification of sugar molecules by addition substituents other than hydroxyl group.

-Amino sugars, acidic sugars, deoxy sugars, sugar alcohols, glycosylamines, and sugar phosphates are examples of carbohydrate derivatives.

-After combining with elements, a transformed molecule of sugar resembles structure of a sugar and an added substituent; however, it is not considered as sugar anymore because its function and characteristics has changed.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
