ACC A&P Assessment Study Guide Test
Describe the levels of organization in multicellular organisms starting with atoms
and ending with organisms. correct answers- atoms, molecules, organelles, cells, tissues, organs, organ
systems, organisms
Define the term homeostasis. correct answers- the maintenance of dynamic steady in the internal
environment "strive for stability"
Describe, in general terms, how negative and positive feedback mechanisms are
used by organisms to maintain homeostasis. correct answers- Neg/Pos feedback are the general
mechanisms of nervous or hormonal regulation.
- Neg. Feedback provides stable, long term control.
- Pos. Feedback reinforces original deviation and causes rapid and temporary changes in a variable.
State the basic units of the metric system for length, mass, time and volume. correct answersMeter (m)
Gram (g)
Liter(l)
Degree Celsius(ºC)
Second (s)
Identify the fraction or multiple associated with each of the following prefixes: kilo,
deci, centi, milli, micro, and nano. correct answersKilo (k)= 10 to the 3rd
Deci (d)= 10 to the negative 1
Centi (c) = 10 to the negative 2
Milli (m)= 10 to the negative 3
Micro (?)= 10 to the negative 6
nano (n) = 10 to the negative 9
, Identify the common chemical symbols correct answersoxygen(O),
carbon (C),
hydrogen,
nitrogen (N),
calcium (Ca),
potassium (K),
sodium (Na),
chlorine (Cl),
iron (Fe),
and phosphorus (P)
Identify the chemical formulas for correct answerscarbon dioxide(CO2),
carbon monoxide (CO),
water (H2O),
hydrochloric acid, (HCI)
sodium chloride (NaCl),
glucose (C6H12O6),
and sodium bicarbonate (NaHCO3)(also known as sodium hydrogen carbonate).
Define the term isotope correct answersEach of two or more forms of the same element that contain
equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative
atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Recognize that isotopes are used in diagnosis and treatment in medicine. correct answersNuclear
medicine is a medical specialty that involves the application of radioactive substances to diagnose or
treat disease. ... Common isotopes that are used in nuclear imaging include: fluorine gallium, krypton
rubidium, nitrogen, technetium, indium, iodine, xenon and thallium.
Define the term molecule: correct answersA molecule is the smallest particle in a chemical element or
compound that has the chemical properties of that element or compound. Molecules are made up of
atoms that are held together by chemical bonds. Molecule-the fundamental components of chemical
compounds and are the smallest part of a compound that can participate in a chemical reaction
