APHY 101 FINAL EXAM 2026\2027
QUESTIONS AND ANSWERS.
1. 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
2. What are the levels of organization? - CORRECT ANSWER -subatomic particles,
atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system,
organism
3. What are the requirements of life? - CORRECT ANSWER -Water, food, oxygen,
heat, pressure
4. 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)

5. Define homeostasis - CORRECT ANSWER -Body's maintenance of a stable
environment
6. 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
7. Define matter - CORRECT ANSWER -Anything that takes up space and has mass
(weight). It is composed of elements.
8. Define element - CORRECT ANSWER -fundamental substance composed of
chemically identical atoms
9. Define atoms - CORRECT ANSWER -smallest particle of an element; basic unit
of matter
10.What is the structure of an atom? - CORRECT ANSWER -An atom consists of a
nucleus containing protons and neutrons, with electrons in
11.orbit around the nucleus.
, Page|3
12.Atomic nucleus - CORRECT ANSWER -the nucleus contains protons and
neutrons
13.Proton - CORRECT ANSWER -subatomic particle that has a positive charge
14.Neutron - CORRECT ANSWER -subatomic particle that has no charge
15.Electron - CORRECT ANSWER -subatomic particle that has a negative charge
16.Atomic number - CORRECT ANSWER -number or protons in nucleus
17.Atomic mass - CORRECT ANSWER -number of protons plus number of neutrons
18.What are covalent bonds? - CORRECT ANSWER -Covalent bonds are formed
when atoms share electrons to become stable with filled
19.outer shells
, Page|4
20.What are ionic bonds? - CORRECT ANSWER -2 oppositely charged atoms form
this bond when electrons are transferred from one atom to another atom
21.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
22.Define ion - CORRECT ANSWER -When atoms gain or lose electrons, they
become ions.
23.Define synthesis reaction - CORRECT ANSWER -Two or more atoms or
molecules are joined together
24.Define decomposition reaction - CORRECT ANSWER -Larger molecules are
broken down into smaller ones
25.Define exchange reaction - CORRECT ANSWER -Parts of molecules trade places
