The passage states that lack of sleep weakens immune function and increases susceptibility to illness. This supports the conclusion that adequate sleep supports immune health.

Copper is a chemical element, meaning it consists of only one type of atom. If a penny were made entirely of copper, it would be classified as a pure substance and specifically as an element. Compounds consist of two or more different elements chemically bonded together. Mixtures contain substances physically combined, not chemically bonded. Since the penny is composed of only copper atoms, it does not qualify as a mixture or a compound. The NEX Science exam frequently includes questions on classification of matter, requiring students to distinguish between elements, compounds, and mixtures. Therefore, option D is correct.
