EXAM QUESTIONS WITH COMPLETE
SOLUTIONS
What is the difference between anatomy and physiology? - CORRECT ANSWER-
anatomy is study of body structure and physiology is study of how those structures work
What are the levels of organization and define each - CORRECT ANSWER-organelle:
cell structure that carries out special function in the cell
cell: basic unit of structure & function in a living thing
tissue: a group of similar cells that are organized to do a specific job
organ: a collection of tissues that carry out a specialized function of the body
organ system: group of organs that work together to perform a specific function
organism: a living thing made of a group of organ systems
What are the characteristics of life and define each - CORRECT ANSWER-
Responsiveness to the environment, growth and change, ability to reproduce, have a
metabolism and breathe, maintain homeostasis, being made of cells, passing traits to
offspring
what are the requirements of life? why is each important? - CORRECT ANSWER-water:
needed to transport substances to regulate the body
food: needed to supply energy and for regulation
oxygen: needed to help release energy from food substances
heat: needed to regulate the rate of metabolic processes
pressure: needed for breathing and circulation
,Define homeostasis - CORRECT ANSWER-Maintaining a stable internal environment
what is a homeostatic mechanism - CORRECT ANSWER-tendency to maintain
relatively constant conditions in the environment
Define matter, element and atom. What is the basic unit of matter? - CORRECT
ANSWER-matter: any substance that has mass and takes up space
atom: smallest unit of ordinary matter
basic unit of matter: atoms
what is the structure of an atom - CORRECT ANSWER-protons, neutrons, electrons
define nucleus, proton, neutron, and electron. What charges do each of these particles
have? - CORRECT ANSWER-nucleus: central core of an atom, positive
proton: stable subatomic particle, positive
neutron: subatomic particle, no charge
electron: stable subatomic particle, negative
what are covalent, ionic and hydrogen bonds and what are the differences between the
three? - CORRECT ANSWER-covalent: 2 atoms shared 1 or more molecules
hydrogen: weak bond between 2 opposite positively charged sides of 2 or more
molecules
ionic bond: atom gives away one or more electrons to another atom
Define synthesis - CORRECT ANSWER-the production of chemical compounds by
reaction from simpler materials.
, Define decomposition - CORRECT ANSWER-the process of breaking down
deliverables and project work into smaller more manageable components.
Define exchange reaction - CORRECT ANSWER-parts of molecules trade places
What is a reactant? - CORRECT ANSWER-a substance that takes part in and
undergoes change during a reaction.
What is a product? - CORRECT ANSWER-The elements or compounds produced by a
chemical reaction.
What is a catalyst? - CORRECT ANSWER-substance that speeds up the rate of a
chemical reaction
what happens / what is produced when salts dissolve in water? - CORRECT ANSWER-
water molecules pull sodium and chloride apart, breaking the ionic bond - a
homogeneous system is produced
what is an acid? - CORRECT ANSWER-An acid is a source of hydrogen ions, H⁺
What is a base? - CORRECT ANSWER-proton acceptor
What is the pH scale? - CORRECT ANSWER-measures how acidic or basic a
substance is
what ions are involved in the ph scale - CORRECT ANSWER-hydrogen and hydroxide
ions
