Exam Questions With 100% Verified
Answers
What is the difference between a hypothesis and a prediction? -
correct answer ✅A hypothesis is an idea; a prediction is something
that follows from a hypothesis and that you can measure
How do biologists test their ideas about the natural world? -
correct answer ✅Scientists make predictions based on hypotheses
they have developed, and then design experiments to test those
predictions
Why is it important to perform multiple trials in an experiment --
meaning that you include many test individuals or samples? -
correct answer ✅To make it more likely that the results are not
due to a few unusual individuals or circumstances
Researchers do an experiment to test the hypothesis that Douglas
fir trees put more resources into reproduction when they are
infected with a fungus that causes a fatal disease. They establish
study plots in a group of 50-year-old Douglas fir where the disease
is not present. At random, they infect half the trees with the
disease-causing fungus. Then they measure how many cones and
seeds are produced by infected versus uninfected trees.

Answers
1.) What prediction follows from the hypothesis?
2.) Which treatment would be considered the control?
3.) Why is it important to do the experiment in the same group of
same-aged trees?
4.) Why is it important that they assigned trees to the infected
versus uninfected groups at random?
5.) If the hypothesis is wrong, and being infected with the fungus
has no impact at all on reproduction, what should they observe? -
correct answer ✅1.) The infected trees will produce more seeds
than uninfected trees
2.) The uninfected trees
3.) To eliminate the possibility that the results are due to
differences in age, soil, moisture, or other relevant variables

4.) If assignment was not random, the result could be do to
something other than the difference in infection
5.) There will be no difference in the number of seeds produced by
infected versus uninfected seeds
What is the process component of the theory of special creation? -
correct answer ✅Species were created, instantaneously and
independently of each other, by God.
What is the pattern component of the theory of special creation? -
correct answer ✅Species are recent, unrelated to each other, and
do not change through time.
What is the pattern component of Lamarckian evolution? -
correct answer ✅Species change in a progressive manner--
meaning that they get larger and more complex over time.
The geologic record and radiometric dating are inconsistent with
the theory of special creation. Why? -
