Water coming to a boil on a stove, ice melting, and steam from a cup of coffee are all examples of which of the following?

66% Answer Correctly

	reflection
	radiation
	conduction
	convection

The rows of the Periodic Table of the Elements are called:

62% Answer Correctly

	groups
	shells
	families
	periods

Solution

The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number.

In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:

71% Answer Correctly

	sugar
	mitochondria
	oxygen
	water

Solution

Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.

Elements in the same group in the Periodic Table of the Elements have the same:

51% Answer Correctly

	number of electrons in their outer electron shell
	number of electrons
	number of electron shells
	number of atomic mass units

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.
