1

Which of the following is not a medium for sound waves?

61% Answer Correctly

vacuum

liquid

none of these is a medium for sound waves

solid
Solution

A vibrating object produces a sound wave that travels outwardly from the object through a medium (any liquid or solid matter). The vibration disturbs the particles in the surrounding medium, those particles disturb the particules next to them, and so on, as the sound propagates away from the vibration.

2

What part of the brain is responsible for for balance, movement, and muscle coordination?

70% Answer Correctly

medulla

cerebrum

brainstem

cerebellum
Solution

The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.

3

Water freezing or boiling is an example of which of the following?

80% Answer Correctly

heating

phase transition

sublimation

cooling
Solution

A substance undergoes a phase transition when it moves from one state of matter to another, for example, when water freezes or boils.

4

A major difference between sound waves and light waves is which of the following?

70% Answer Correctly

a sound wave is mechanical while a light wave is electromagnetic

a sound wave cannot travel through a vacuum

a sound wave is much slower than a light wave

all of these are correct
Solution

A vibrating object produces a sound wave that travels outwardly from the object through a medium (any liquid or solid matter). The vibration disturbs the particles in the surrounding medium, those particles disturb the particules next to them, and so on, as the sound propagates away from the vibration.

5

Which of these digestive enzymes is not produced by the pancreas?

63% Answer Correctly

gastric acid

trypsin

lipase

pancreatic amylase
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.
