QUESTIONS WITH CORRECT ANSWERS
A fish swims through the water by using its fins to push water backwards. Pushing water
backwards propels the fish forward through the water. This most nearly fits which of
Newton's Laws?:
A. Newton's First Law: Force=mass(acceleration)
B. Newton's Second Law: objects in motion will stay in motion unless acted upon by a
force, objects at rest will stay at rest unless acted upon by a force
C. Newton's Third Law: For every action, there is an equal and opposite reaction. -
Answer-C. Newton's Third Law: For every action, there is an equal and opposite
reaction.
Researchers want to conduct a study using random sampling. What is random
sampling?
A. Individuals are randomly selected from the population. Every individual has the same
probability of being selected.
B. A control group is selected and every other individual is used for data.
C. The population is divided into subgroups. Each subgroup has several individuals that
are selected.
D. The population is divided into age groups and individuals are chosen at random from
within those age groups. - Answer-A. Individuals are randomly selected from the
population. Every individual has the same probability of being selected.
Which of the following depictions best represents evolution and why?
Formation of a mountain over time
A husky dog descended from a wolf
A. The formation of a mountain over time. The mountain changed and formed. It
evolved.
B. The husky dog. The dog is the product of modifications of inheritance over time. -
Answer-B. The husky dog. The dog is the product of modifications of inheritance over
time.
Your body turns food into sugar by an initial chemical reaction from chemicals in your:
Read the following passage:
, It all starts with that first bite of pizza. Your teeth tear off that big piece of crust. Your
saliva
glands start spewing out spit like fountains. Your molars grind your pizza crust,
pepperoni, and
cheese into a big wet ball. Chemicals in your saliva start chemical reactions. Seemingly
like
magic, starch in your pizza crust begins to turn to sugar! A couple of more chews and,
then, your
tongue pushes the ball of chewed food to the back of your throat. A trap door opens,
and there
it goes, down your gullet!
