EXAM IVY TECH QUESTI ON AND ANSWER
Question : What is the difference between anatomy and
physiology?
Correct answer: Anatomy is the study of the structure of body
parts, whereas physiology is the study of the function of body parts
Question : What are the levels of organization?
Correct answer: subatomic particles, atom, molecule,
macromolecule, organelle, cell, tissue, organ, organ system, organism
Question : What are the requirements of life?
Correct answer: Water, food, oxygen, heat, pressure
Question : What are the characteristics of life?
Correct answer: Movement (internal or gross); Responsiveness
(reaction to internal or external change); Growth (increase in size without change in shape); Reproduction (new organisms or new cells); Respiration (use of oxygen; removal of CO2); Digestion (breakdown of food); Absorption (movement of

substances through membranes and into fluids); Circulation (movement within body fluids); Assimilation (changing nutrients into chemically different forms); Excretion (removal of metabolic wastes)
Question : Define homeostasis
Correct answer: Body's maintenance of a stable environment
Question : What is a homeostatic mechanism?
Correct answer: the body maintains homeostasis through a
number of self-regulating control systems; examples are regulating body temperature and pressure sensitive receptors to regulate body pressure
Question : Define matter
Correct answer: Anything that takes up space and has mass
(weight). It is composed of elements.

Question : Atomic number
Correct answer: number or protons in nucleus
Question : Atomic mass
Correct answer: number of protons plus all of neutrons
Question : What are covalent bonds?
Correct answer: Covalent bonds are formed when atoms share
electrons to become stable with filled outer shells
Question : What are ionic bonds?
Correct answer: 2 oppositely charged atoms form this bond
when electrons are transferred from one atom to another atom
Question : What are hydrogen bonds?
Correct answer: Weak attraction between positive end of one
polar molecule and negative end of another polar molecule; formed between water molecules
