ACC A&P ASSESSMENT STUDY GUIDE EXAM
WITH CORRECT ANSWERS
Describe the Levels of organization in multi cellular organisms starting with
atoms and ending with organisms. - ANSWER The levels of organization
are atoms, molecules, organelle, cell, tissue, organ, organ system and
organism.
Define the term homeostasis. - ANSWER Homeostasis is an organism or
cell that regulates it's internal conditions by a system of feedback controls.
Describe, in general terms, how negative and positive feedback
mechanisms are used by organisms to maintain homeostasis. - ANSWER
Negative Feedback; is the response opposite of original deviation returns
the variable to a set point.
EXAMPLE: Blood Glucose, temperature.
Positive Feedback; reinforces original deviation causes rapid and
temporary change in a variable.
EXAMPLE: blood clotting

ATOMS, MOLECULES, BONDS, and PROPERTIES of MATTER: -
ANSWER
Define the term element. - ANSWER An element is a substance that
cannot be further broken down.
Identify the common chemical symbols for: Oxygen, Carbon, Hydrogen,
Nitrogen, Calcium, Potassium, Sodium, Chlorine, Iron and Phosphorus. -
ANSWER Oxygen: O
Carbon: C
Hydrogen: H
, Nitrogen: N
Calcium: Ca
Potassium: K
Sodium: Na
Chlorine: Cl
Iron: Fe
Phosphorus: P
Identify the chemical formulas for carbon dioxide, carbon monoxide, water,
hydrochloric acid, sodium chloride, glucose, and sodium bicarbonate. ( Also
known as sodium hydrogen carbonate. ) - ANSWER Carbon Dioxide: C02
Carbon Monoxide: CO
Water: H2O
Hydrochloric Acid: HCl
Sodium Chloride: NACl
Glucose: C6Hl2O6
Define the term atom. - ANSWER An atom is the basic and smallest unit of
a chemical element.
Describe the basic structure of an atom. (Protons, Neutrons and Electrons.)
- ANSWER Atoms consist of electrons surrounding a nucleus that contains
neutrons and protons.
Identify the charge and the location in the atom of protons, neutrons and
electrons. - ANSWER Electrons are on the outside with a negative charge.
Protons are in the center and have a positive charge. Neutrons are in the
nucleus as well, but are neutral.
Define the term isotope. - ANSWER An isotope is atoms of the same
element with different numbers of neutrons.
Recognize that isotopes are used in diagnosis and treatment in medicine. -
ANSWER
Define the terms molecule and ion. Explain the role of electrons in chemical
bonding. - ANSWER Molecule: it consists of two or more atoms held
together by chemical bonds.
