The dwarf planet Pluto is located where?

63% Answer Correctly

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

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.

63% Answer Correctly

	families
	periods
	shells
	groups

Gametes have how many pairs of chromosomes?

76% Answer Correctly

	23
	46
	4
	2

Solution

Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.

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

82% Answer Correctly

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

Solution

Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.

73% Answer Correctly

	primary
	secondary
	all of these
	tertiary

Solution

Most animals consume other organisms to survive. Consumers (heterotrophs) are divided into three types, primary, secondary, and tertiary, based on their place in the food chain.
