The dwarf planet Pluto is located where?

63% Answer Correctly

	in the Kuiper Belt
	in the asteroid belt
	outside the solar system
	between the orbits of Jupiter and Saturn

Solution

The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.

In fermentation, what replaces oxygen in anaerobic respiration?

63% Answer Correctly

Generally, an atom has __________ negative electrons orbiting the nucleus as it does positive protons inside.

67% Answer Correctly

	more
	double the number of
	fewer
	equal numbers of

Solution

An electron is a subatomic particle that orbits the nucleus of an atom. It carries a negative electric charge. Generally, an atom has the same number of negative electrons orbiting the nucleus as it does positive protons inside.

What is a major difference between the somatic and autonomic nervous systems?

82% Answer Correctly

	each belongs to a different nervous system
	one controls voluntary activity, one controls involuntary activity
	one is inherited, the other is learned
	one controls thinking, the other controls feeling
