Q: Q: What do nonvascular plants reproduce with? Read this paragraph and choose the correct option from the provided answers: Nonvascular plants are low-growing, reproduce with spores, and need a moist habitat. Choices: - photosynthesis - toxins - vascular plants - spores A:
A: spores

Q: Q: What kind of bonds does boron form rather than metallic lattices? Read this paragraph and choose the correct option from the provided answers: Boron forms multicenter bonds rather than metallic lattices with delocalized valence electrons. Why does it prefer this type of bonding? Does this explain why boron behaves like a semiconductor rather than a metal? Explain your answer. Choices: - magnetic bonds - electron bonds - bilateral - multicenter A:
A: multicenter

Q: Q: Which state of matter has an intermediate level of entropy between solid and gas? Read this paragraph and choose the correct option from the provided answers: As expected, the entropy values for solids are low, the values for gases are high, and the ones for liquids are intermediate. Another observation can be made by looking at the three hydrocarbon gases at the end of the table. For similar molecules, a higher molecular weight generally leads to a larger standard entropy value. Although this is a drastic oversimplification, we can think of this in terms of the electrons that make up each molecule. A larger molecular weight generally means more protons, which also means more electrons. There are more ways to arrange a large number of electrons within a molecule than there are to arrange a smaller number. Although these arrangements are heavily constrained by the positions of the various nuclei, there is still an overall trend for larger molecules to have higher entropy values. Choices: - plasma - water - metal - liquid A:
A: liquid

Q: Q: What do obligate aerobes need to live? Read this paragraph and choose the correct option from the provided answers: Organisms that are obligate aerobes need oxygen to live. That is, they use oxygen as a terminal electron acceptor while making ATP (see the "Cellular Respiration" concept). Humans are obligate aerobes, and so are Mycobacterium tuberculosis bacteria. M. tuberculosis causes tuberculosis (TB). Obligate aerobes are found only in places with molecular oxygen. Choices: - blood - acid - dioxide - oxygen A:
A: oxygen
