APHY 101 FINAL EXAM 2026/2027 ACTUAL QUESTIONS WITH
VERIFIED ANSWERS ALREADY GRADED A+.
What is the difference between anatomy and physiology? - (ANSWER)Anatomy is the study of the
structure of body parts, whereas physiology is the study of the function of body parts
What are the levels of organization? - (ANSWER)subatomic particles, atom, molecule, macromolecule,
organelle, cell, tissue, organ, organ system, organism
What are the requirements of life? - (ANSWER)Water, food, oxygen, heat, pressure
What are the characteristics of life? - (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)
Define homeostasis - (ANSWER)Body's maintenance of a stable environment
What is a homeostatic mechanism? - (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
Define matter - (ANSWER)Anything that takes up space and has mass (weight). It is composed of
elements.
Define element - (ANSWER)fundamental substance composed of chemically identical atoms
Define atoms - (ANSWER)smallest particle of an element; basic unit of matter

VERIFIED ANSWERS ALREADY GRADED A+.
What is the structure of an atom? - (ANSWER)An atom consists of a nucleus containing protons and
neutrons, with electrons in
orbit around the nucleus.
Atomic nucleus - (ANSWER)the nucleus contains protons and neutrons
Proton - (ANSWER)subatomic particle that has a positive charge
Neutron - (ANSWER)subatomic particle that has no charge
Electron - (ANSWER)subatomic particle that has a negative charge
Atomic number - (ANSWER)number or protons in nucleus
Atomic mass - (ANSWER)number of protons plus number of neutrons
What are covalent bonds? - (ANSWER)Covalent bonds are formed when atoms share electrons to
become stable with filled
outer shells
What are ionic bonds? - (ANSWER)2 oppositely charged atoms form this bond when electrons are
transferred from one atom to another atom
What are hydrogen bonds? - (ANSWER)Weak attraction between positive end of one polar molecule and
negative end of another polar molecule; formed between water molecules
Define ion - (ANSWER)When atoms gain or lose electrons, they become ions.

VERIFIED ANSWERS ALREADY GRADED A+.
Define synthesis reaction - (ANSWER)Two or more atoms or molecules are joined together
Define decomposition reaction - (ANSWER)Larger molecules are broken down into smaller ones
Define exchange reaction - (ANSWER)Parts of molecules trade places
Define reactant - (ANSWER)The starting materials of the reaction - the atoms, ions, or molecules
Define product - (ANSWER)Substances formed at the end of the chemical reaction
Define catalyst - (ANSWER)influence the rates of chemical reactions
What is an acid? - (ANSWER)Electrolytes that release hydrogen ions in water
What is a base? - (ANSWER)Electrolytes that release ions that combine with hydrogen ions in water
What is a salt? - (ANSWER)Acids and bases that react to form water and electrolytes
What is a pH scale? - (ANSWER)represents the concentration of hydrogen ions [H+] in solution
Neutral solution - (ANSWER)pH 7;
indicates equal concentrations of H+
and OH-
