45% Answer Correctly

	solid
	makes up most of the Earth's volume
	primarily solid
	liquid

Solution

In the Periodic Table of the Elements, elements in the same column belong to the same:

64% Answer Correctly

	atomic number
	period
	group
	family

Solution

The columns of the Periodic Table are called groups and all elements in a group have the same number of electrons in their outer electron shell. The group that an element occupies generally determines its chemical properties as the number of outer shell electrons establishes the way it reacts with other elements to form molecules. So, because each element has the same number of electrons in its outer shell, each has similar reactivity.

Poor balance could indicate an issue with which part of the nervous system?

64% Answer Correctly

	medulla
	cerebrum
	cerebellum
	spinal cord

Solution

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

The crust and upper mantle of the earth is called the:

62% Answer Correctly

	hydrosphere
	lithosphere
	atmosphere
	geosphere

Solution

The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).

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

55% Answer Correctly

	heterozygous
	allele
	homozygous
	chromosome

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.
