ANSWERS (GRADED A+)
True or False? Biodiversity on Earth will likely decrease in the near future. -
ANSWERFalse
True or False? Scientists believe in evolution even though they currently lack
evidence for the theory. - ANSWERFalse
Biologists used induction to hypothesize that snakes use pits to see heat. -
ANSWERTrue
Biologists used induction to predict the percentage of times that a snakes with
sealed pits would choose the cool box. - ANSWERFalse
Each treatment (sealed pits vs. unsealed pits) was replicated 20 times. -
ANSWERFalse
The experiment would be flawed if snakes were not randomly assigned to each
treatment. - ANSWERTrue
Opposition to irrational numbers was based on evidence that such numbers cannot
exist. - ANSWERFalse - (No direct evidence for or against irrational numbers was
used to oppose the idea. A religious belief based on faith was used instead.)
Opposition to irrational numbers stemmed from a worldview involving naturalistic
evolution. - ANSWERFalse - (A creationist worldview was the reason for opposing
irrational numbers.)
The belief that irrational numbers cannot exist reflects religion more than science. -
ANSWERTrue - (The notion that God(s) created a perfect world is the product of a
religion)
One of John's parents must be heterozygous for the gene that determine the
moistness of ear wax. - ANSWERTrue (Since the four siblings differ in phenotype,
one of the parents must carry a recessive allele.)
Based on the phenotypes of John and his siblings, the allele for moist ear wax is
more likely dominant than recessive. - ANSWERFalse (Most of John's family have
dry ear wax, which would be a more likely outcome if the allele for moist ear wax
were recessive.)
, If John's father was homozygous for the gene that causes moist ear wax, the allele
for dry ear would have to be dominant. - ANSWERTrue (Since John's siblings have
dry ear wax, they would need a dominant allele from their mother to produce this
phenotype).
If John's father was homozygous for the gene that causes moist ear wax, his mother
would have to be heterozygous for this gene. - ANSWERTrue (Since John has moist
ear wax and his other siblings do not, the mother would need to supply one allele to
John and a different allele to his siblings).
Modern mathematicians accept irrational numbers because such numbers provide
more accurate solutions to problems than whole numbers do. - ANSWERTrue -
(irrational numbers are used because they enhance calculations of measurable
properties, such as the area of a circle).
The scientific method relies on ____________.
models
observations
experiments
all of the above - ANSWERall of the above
A model is a formal description of a scientific hypothesis. Which of the following
types of models provides the most precise description of a hypothesis?
verbal
graphical
mathematical
All of the above are equally precise - ANSWERmathematical
An experiment enables one to demonstrate that a correlation between two variables
results from cause and effect.
True
False - ANSWERTrue
A well designed experiment ____________.
a. controls for environmental and genetic factors.
b. involves replication of experimental subjects.
c. randomizes experimental subjects among treatments.
d. achieves all of the above. - ANSWERd. achieves all of the above.
The group of snakes whose pits were left unsealed served as a control in this
experiment. - ANSWERTrue
Use this information to answer the questions below.
