Answer:
Monosaccharides are simple sugars with a basic formula Cⁿ (H2O)ⁿ. They are classified according to the number of carbon atoms they contain: tetroses (4), pentoses (5) and hexoses (6). There are also mosaccharides with 3 carbon atoms, for example the Dihydroxyacetone.
Explanation:
Monosaccharides have to be aldehydes (-CHO) or ketones (-COO) with more than one alcohol function, which will be located in different carbons.
A closed system is a system that makes no physical or chemical exchanges with its environment. Of these systems provided as choices (tree, human, clock, car), only a clock does not make exchanges with the environment, except for energy.
Therefore, of that list, only a clock would be a closed system.
