◍ Chemical Energy.
Answer: Stored in bonds of chemical substances
◍ Rate of Chemical Reaction.
Answer: Affected by temperature, concentration of reactant, particle size
◍ middle ear cavities.
Answer: found in the skull; serve as chambers for transmitting and
amplifying sound
◍ Parasagittal Plane.
Answer: A sagittal section that is to the right or left of the body midline (and
, so divides the body into unequal-sized left and right portions)
◍ Effector.
Answer: Organ that can cause a change in value- an organ (a gland or
muscle) that becomes active in response to nerve impulses
◍ Distal.
Answer: Describes a position farther from the point of attachment or the
trunk of the body
◍ Renewal.
Answer: Process by which worn-out cells are replaced
◍ Ion.
Answer: Atom with net electric charge due to loss or gain of one or more
electron
◍ Abdominopelvic Cavity.
Answer: Division of the anterior (ventral) cavity that houses the abdominal
and pelvic viscera.
◍ Nutrient.
Answer: Chemical obtained from foods and beverages that is critical to
human survival
◍ Valence Shell.
Answer: Outermost electron shell
◍ Ventral Body Cavity.
Answer: Larger body cavity located anterior to the posterior (dorsal) body
cavity; includes the serous membrane-lined pleural cavities of the lungs,
pericardial cavity of the heart, and peritoneal cavity for the abdominal and
pelvic organs; also referred to as anterior body cavity.
◍ Excretion.
Answer: The process whereby the undigested residue of food and the waste
products of metabolism are eliminated, material is removed to regulate the
composition of body fluids and tissues, or substances are expelled to
