Earth's history is divided into time periods, which of these is the longest time period?

67% Answer Correctly

	epoch
	age
	eon
	era

Solution

The Earth is approximately 4.6 billion years old and its history is divided into time periods based on the events that took place and the forms of life that were dominant during those periods. The largest graduation of time is the eon and each eon is subdivided into eras, eras into periods, periods into epochs, and epochs into ages.

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

51% Answer Correctly

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

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.

Reproductive haploids are also known as:

62% Answer Correctly

	diploids
	ovum
	gametes
	sperm

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.
