Document Summary
Living things require energy to maintain internal organization (homeostasis) and to produce the other phenomena associated with life: growth: maintenance of a higher rate of anabolism than catabolism. A growing organism increases in size in all of its parts, rather than simply accumulating matter: adaptation: the ability to change over a period of time in response to the environment. If a hypothesis is correct and we test it, we can expect a certain outcome. Isotopes: all atoms of an element have the same number of protons but may differ in number of neutrons, isotopes are two atoms of an element that differ in number of neutrons. A compound is a combination of two or more different elements: bonding capacity is called the atom"s valence xi. Electronegativity is an atom"s attraction for the electrons in a covalent bond xii. The more electronegative an atom, the more strongly it pulls shared electrons toward itself xiii.
