69% Answer Correctly

	stratus clouds
	cumulus clouds
	cirrus clouds

Which of the following is not true about simple magnets?

62% Answer Correctly

	same poles repel each other
	all of these are untrue
	opposite poles attract each other
	opposite poles repel each other

Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.

In the pancreas, lipase converts fat to:

64% Answer Correctly

	amino acids
	complex carbohydrates
	simple sugars
	glycerol and fatty acids

Solution

The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.

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

82% Answer Correctly

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

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.
