Bronchioles, alveolus, and capillaries are vital parts of which bodily system?

72% Answer Correctly

	digestion
	respiration
	nervous
	circulation

Solution

The trachea branches into the left and right bronchi which each lead to a lung where the bronchi subdivide into smaller tubes called bronchioles. Each bronchiole ends in a small sac called an alveolus which allows oxygen from the air to enter the bloodstream via tiny blood vessels called capillaries.

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

58% Answer Correctly

	temperate front
	stationary front
	warm front
	cold 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.

Which of the following would be used in eye glasses to correct farsightedness?

64% Answer Correctly

	convex lens
	convex mirror
	concave mirror
	concave lens

Solution

Unlike curved mirrors that operate on the principle of reflection, lenses utilize refraction. A convex lens is thicker in the middle than on the edges and converges light while a concave lens is thicker on the edges than in the middle and diffuses light. A common use for curved lenses is in eye glasses where a convex lens is used to correct farsightedness and a concave lens is used to correct nearsightedness.

Within DNA, a variety of a particular gene is called a(n):

55% Answer Correctly

	heterozygous
	homozygous
	chromosome
	allele

Solution

The gene is the base unit of inheritance and is contained within DNA. A gene may come in several varieties (alleles) and there are a pair of alleles for every gene. If the alleles are alike, a person is homozygous for that gene. If the alleles are different, heterozygous.
