ILTS 305 EXAM COMBINED SET
QUESTIONS WITH CORRECT
ANSWERS
Newton's first law - Answer-An object at rest stays at rest and an object in motion stays
in motion with the same speed and in the same direction unless acted upon by an
unbalanced force; inertia
Newton's second law - Answer-object's acceleration is directly proportional to the net
force acting on the object and inversely proportional to the object's mass; F=ma
Doppler effect - Answer-effect of relative motion of the source of the wave and the
location of the observer has on waves; pitch of sound is different not because emitted
frequency changes but because of received frequency changes
Reflection - Answer-rebound of light wave from a surface back toward the medium from
where it came
Refraction - Answer-change in the direction of light wave when it passes through a
transparent medium with a different optical density from the one in which the wave had
been traveling
-light bends
Neutrons - Answer-uncharged particles contained within the nucleus
Nucleon - Answer-refers collectively to both neutrons and protons
hydrogen bond - Answer-weak attraction between a hydrogen atom and another atom
(i.e. N, O, F)
Ionic bond - Answer-Formed when one or more electrons are TRANSFERRED from
one atom to another
covalent bond - Answer-A chemical bond formed when two atoms SHARE electrons
Solution - Answer-homogenous mixture
pH (potential of hydrogen) - Answer-measurement of hydrogen ions
lower pH means ______ H+ concentration - Answer-higher; acidic
, higher pH means _____ H+ concentration - Answer-lower; basic
Properties of water (7) - Answer--high polarity
-hydrogen bonding
-cohesiveness
-adhesivenesss
-high specific heat
-high latent heat
-high heat of vaporization
Organic compounds requirements (2) - Answer--contain carbon

Stroma - Answer-area inside chloroplast where reactions occur and starches are
created
Hershey and chase - Answer-experiment showed that DNA not protein is responsible
for transferring genetic material
Countries who first tried to colonize America - Answer-Spain and France
Primary reasons for English colonization - Answer--mercantilism (colonies would
provide raw materials to ensure England would exports>imports)
-colonists' desire to be free from religious persecution (Church of England v
Catholocism)
French and Indian War - Answer-war over territory between English colonies and
French colonies
What ended the French and Indian War? - Answer-Treaty of Paris I

Treaty of Paris (1782) - Answer-Marked official ending on war
-granted independence to the colonies
-generous territorial rights
Articles of Confederation - Answer-A weak constitution that governed America during
the Revolutionary War.
