Explanation:
Water is the most abundant substance in the body. An average healthy adult is 45 to 75 percent water. Percent of water declines with age. Males have more body water than females.
X - linked traits appear more often in males because males only have one x chromosome. One copy of an x - linked trait is all that a male would need to possess that trait. Females have two x chromosomes, so they would require 2 copies of the x - linked trait in order to possess it.
Certain fossils, called index fossils, help geologists match rock layers.
