⩥ Polar. Answer: Water has a slight positive charge on one side of the
molecule and a slight negative charge on the other side.
⩥ Cohesion. Answer: Water molecules attracted to other water
molecules.
⩥ Capillary Action. Answer: The ability of a liquid to flow in narrow
spaces without the assistance of, and in opposition to, external forces of
gravity.
⩥ Surface tension. Answer: Property of water created by cohesion and
adhesion, allows some insects to walk on water.
⩥ High Specific Heat. Answer: Water resists temperature changes.
⩥ Universal solvent. Answer: Water can separate the ions in many
compounds.
⩥ Covalent bond. Answer: Electrons are shared.
,⩥ Ionic bond. Answer: Electrons are transferred.
⩥ Isotope. Answer: Atoms of the same element with a different number
of neutrons.
⩥ Ion. Answer: Atom with a negative charge (because it gained
electrons) or a positive charge (because it lost electrons).
⩥ Matter. Answer: Anything that occupies space; it cannot be created or
destroyed.
⩥ Atom. Answer: The fundamental unit of matter.
⩥ Proton. Answer: Positive charged part of an atom; number of these
determines the atomic number.

,⩥ Adhesion. Answer: Water sticking to other things.
⩥ Homeostasis. Answer: An organism's abilility to maintain a stable
internal environment.
⩥ Evaporative cooling. Answer: Form of homeostasis that allows
organisms to maintain a stable internal temperature when they are
getting too hot.
⩥ pH. Answer: Measurment of the number of hydrogen ions in a
solution.
⩥ Acids. Answer: pH lower than 7
⩥ Neutral solutions like H2O. Answer: pH equal to 7
⩥ Bases. Answer: pH higher than 7
⩥ Buffer. Answer: Mixture that can react with an acid or a base to keep
the pH within a particular range.
⩥ CHNOPS. Answer: The six essential elements of living things.
, ⩥ Structure of Carbohydrates. Answer: Structure:
⩥ Structure of Nucleotide. Answer: Structure:
⩥ Structure of Phospholipid. Answer: Structure:
⩥ Structure of DNA. Answer: Structure:
⩥ Structure of Amino Acid. Answer: Structure:
