WITH EXPERTLY AND CORRECTLY ANSWERED
QUESTIONS| ACE YOUR GRADES!!!
What are covalent bonds? - Correct Answer-Covalent bonds are formed when
atoms share electrons to become stable with filled
outer shells
What are ionic bonds? - Correct Answer-2 oppositely charged atoms form this
bond when electrons are transferred from one atom to another atom
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
Define ion - Correct Answer-When atoms gain or lose electrons, they become
ions.
Define synthesis reaction - Correct Answer-Two or more atoms or molecules are
joined together
,Define decomposition reaction - Correct Answer-Larger molecules are broken
down into smaller ones
Define exchange reaction - Correct Answer-Parts of molecules trade places
Define reactant - Correct Answer-The starting materials of the reaction - the
atoms, ions, or molecules
Define product - Correct Answer-Substances formed at the end of the chemical
reaction
Define catalyst - Correct Answer-influence the rates of chemical reactions
What is an acid? - Correct Answer-Electrolytes that release hydrogen ions in water
What is a base? - Correct Answer-Electrolytes that release ions that combine with
hydrogen ions in water
,What is a salt? - Correct Answer-Acids and bases that react to form water and
electrolytes
What is a pH scale? - Correct Answer-represents the concentration of hydrogen
ions [H+] in solution
Neutral solution - Correct Answer-pH 7;
indicates equal concentrations of H+
and OH-
Acidic solution - Correct Answer-pH less than
7; indicates a greater concentration of H+
Basic solution - Correct Answer-pH greater than 7; indicates a greater
concentration of OH-
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
What are the levels of organization? - Correct Answer-subatomic particles, atom,
molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism
, What are the requirements of life? - Correct Answer-Water, food, oxygen, heat,
pressure
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)
Define homeostasis - Correct Answer-Body's maintenance of a stable
environment
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
Define matter - Correct Answer-Anything that takes up space and has mass
(weight). It is composed of elements.
