Updated.
Questions that lead to further scientific inquiry are often inspired by:
A:observations.
B:collaborations and discussions with colleagues.
C:experiments.
D:the scientific literature.
E:All of the answer options are correct. - Answer E: All of the answers are correct
Observations, experiments, collaborations, discussions, and research papers can all lead to
questions, so all of the answer options are correct.
You are carrying out an experiment that involves growing bacteria in various petri dishes.
Unfortunately, you forgot about one of the petri dishes. When you discover it two weeks later,
there is mold (a type of fungus) growing in the dish along with the bacteria. You observe that
the bacteria aren't growing in the area where the fungus is growing. What question might you
ask based on this observation?
A: All of the answer options are correct.
B:Do some of the bacteria grow better in the presence of the fungus than other bacteria?
C:Why are the bacteria not growing near the fungus?
D:Does the fungus kill the bacteria?
E:Does the fungus secrete a substance that inhibits the growth of bacteria? - Answer A: All of
the answer options are correct. All of the questions naturally follow from the observation that
bacteria are not growing in the vicinity of the fungus.
Do all scientific studies start with observations that lead to questions?
A: No, scientific inquiry is carried out in many different ways.
B:Yes, scientists always start by making observations.
C:None of the other answer options is correct.
D:Yes, scientists always start with questions. - Answer A: No, scientific inquiry is carried out
in many different ways. Scientific inquiry often starts with observations that lead to questions,
but not always.
, Darwin collected finches during the voyage of the Beagle (Figure 21.9). He shared the
specimens with other scientists back in England after his travels. Which question could the
scientists who were not on the journey with Darwin ask and answer just from observing the
specimens Darwin brought home?
Figure 21.9 Adaptive radiation in Darwin's finches.
A:How do these birds interact with each other?
B:What do these birds eat on the islands?
C: Do the birds all have similar beak sizes?
D: How long have birds lived on the islands? - Answer C: Do the birds all have similar beak
sizes?
The only question that can be answered simply by observing the bird specimens is the question
about beak sizes. All of the other questions require observing live birds in their natural habitat
or involve examining fossil birds.
Gregor Mendel's experiments are among the most important in all of biology. Mendel studied
traits in pea plants and made observations about the traits over successive generations. Review
Figure 15.5 The first-generation hybrid (F1). What trait was Mendel observing?
Figure 15.5 The first-generation hybrid (F1).
A: number of seeds
B: seed color
C: seed size
D: plant fertility - Answer B: seed color
Although Mendel studied many different traits of pea plants, Figure 15.5 specifically focuses on
his study of seed color.
What kind of bond joins hydrogen to oxygen in a water molecule?
A: nonpolar covalent bond
B: polar covalent bond
C: hydrogen bond
D: ionic bond - Answer B: polar covalent bond
