Primavera Integrated Science B Final
UPDATED Actual Exam Questions and
CORRECT Answers
Which factor helps improve the validity of scientific writing? - CORRECT ANSWER✔✔-
showing evidence of scientific thinking in the writing
using sources that are peer reviewed
fully disclosing all facts—even if they do not support the hypothesis
Which option gives an accurate reason why ethical guidelines are needed for the way
scientific information is communicated? - CORRECT ANSWER✔✔- Businesses can
perform and fund research studies, which potentially creates bias.
Poor research could potentially impact the health and welfare of the public.
Government funding of research studies has the potential to create bias.
Using general theories or principles to make predictions about more specific situations is
known as __________. - CORRECT ANSWER✔✔- deductive reasoning
Consider the scenario.
Lloyd is studying the effect of hamster food on the health of hamsters. He suspects that the
food may be unhealthy. He feeds hamsters various amounts of food over a six-week period.
He weighs the hamsters using a digital lab balance at the beginning of the experiment and
then again at the end of the experiment. Then, he calculates and graphs the change in weight.
Lloyd's data shows that the more food the hamsters ate, the greater the change in their weight.
When writing the conclusion of his report, Lloyd states that the hamster food is not a healthy
choice for lab hamsters since it causes them to gain weight unnecessarily.
What component of scientific argumentation is missing from Lloyd's work? - CORRECT
ANSWER✔✔- logical reasoning
, Read the scenario.
A car starts 10 m north of a reference point. It moves at a constant velocity over the next 5 s,
reaching a position of 10 m south of the reference point.
What is the car's average velocity? - CORRECT ANSWER✔✔- 4 m/s south
Study the distance-time graph of two objects' motion.
Which statement is true about the motion of A and B? - CORRECT ANSWER✔✔- A and B
move at constant velocities, but A is faster than B the entire time. At 10 s, the objects pass
each other with different velocities.
Study the table of an object's motion.
What is the object's acceleration? - CORRECT ANSWER✔✔- 4 m/s2
Which statement identifies when the object changes direction and why? - CORRECT
ANSWER✔✔- The object changes direction at 5 s because the velocity changes from a
positive to a negative value.
Read the scenario.
A car starts from rest and increases its position while speeding up for 4 s. The car then slows
down for 4 s, still increasing its position.
Which graph and explanation represent the motion described?
The line on the velocity-time graph starts at (0,0) because the velocity is initially 0 m/s. The
slope increases because the speed increases. Then the slope decreases to show a decrease in
speed. - CORRECT ANSWER✔✔- The line on the velocity-time graph must start from (0,0)
because its velocity is initially 0 m/s. The slope is constant and positive to show an increase
