What kind of weather front is likely to create clouds and storms?

59% Answer Correctly

	warm front
	cold front
	temperate front
	stationary front

Solution

A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.

Gametes have how many pairs of chromosomes?

76% Answer Correctly

	23
	2
	46
	4

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.

Reproductive haploids are also known as:

62% Answer Correctly

	sperm
	ovum
	diploids
	gametes

Solution

Large, puffy, mid-altitude clouds with a flat base and a rounded top describe which of the following?

74% Answer Correctly

	fog
	cumulus clouds
	stratus clouds
	cirrus clouds

Solution

Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.

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

70% Answer Correctly

	all of these are correct
	a sound wave is mechanical while a light wave is electromagnetic
	a sound wave is much slower than a light wave
	a sound wave cannot travel through a vacuum

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.
