Question 1

Which of the following best describes the difference between science and technology?

Accepted Answer

Science aims to understand natural phenomena, while technology applies scientific knowledge for a specific purpose.

Question 2

A scientist is studying the evolutionary relationship between two species by comparing their DNA sequences. Why is this considered observational data rather than experimental data?

Accepted Answer

Because the scientist is not manipulating variables, but rather observing existing genetic information.

Question 3

Which of the following scenarios best illustrates the repetitive and nonlinear nature of the scientific process?

Accepted Answer

A researcher revises their hypothesis after new data contradicts their initial prediction, then collects more data to test the revised hypothesis.

Question 4

Why is peer review an essential part of the scientific process?

Accepted Answer

It ensures that research is evaluated by qualified experts who were not involved in the study, increasing reliability.

Question 5

A scientist hypothesizes that the red panda is most closely related to raccoons based on physical similarities. Later, DNA evidence suggests otherwise. What does this scenario best demonstrate?

Accepted Answer

The willingness of scientists to revise hypotheses when new evidence emerges.

Question 6

Which equation best represents exponential population growth, as mentioned in the context of Earth's population increase?

Accepted Answer

$$N_t = N_0$ e$$^{rt}$$

Question 7

A biologist uses X-ray crystallography to study the structure of DNA. This is an example of:

Accepted Answer

Technology aiding scientific discovery.

Question 8

Which of the following is a consequence of the interaction between science, technology, and society?

Accepted Answer

Technological advances can improve living standards but also contribute to issues like climate change and extinction.

Question 9

A scientist is testing a hypothesis about the effect of a new drug on cancer cells. After initial results, they adjust their experimental design and retest. This process is best described as:

Accepted Answer

Iterative and adaptive, reflecting the nonlinear nature of scientific inquiry.

Question 10

Which of the following statements about hypothesis testing is most accurate?

Accepted Answer

Hypothesis testing is central to science because it allows for the evaluation and revision of explanations based on evidence.

Question 11

Which of the following best explains why DNA sequence comparisons are useful in determining evolutionary relationships?

Accepted Answer

The more similar the DNA sequences of two species, the more closely related they are likely to be.

Question 12

A group of scientists publishes a study in a peer-reviewed journal. Other scientists attempt to repeat the experiment but get different results. What is the most appropriate next step?

Accepted Answer

Re-examine the original study and experimental design to identify possible sources of error or variation.

Question 13

Which of the following is NOT a characteristic of the scientific process as described in the study materials?

Accepted Answer

It always follows a rigid, linear sequence of steps.

Question 14

A scientist uses published literature to inform their experimental design. This is an example of:

Accepted Answer

Building on the foundation of existing knowledge.

Question 15

Which of the following best describes the relationship between science and technology?

Accepted Answer

Science and technology are interdependent; scientific discoveries often lead to new technologies, and technology can aid scientific research.

Question 16

Which of the following is a societal benefit of scientific literacy?

Accepted Answer

It enables citizens to participate in debates regarding science, technology, and society.

Question 17

A scientist is designing an experiment to test a new hypothesis. Which of the following steps is most likely to occur during the process?

Accepted Answer

The experimental design may be adjusted after initial data are collected.

Question 18

Which of the following is an example of a real-world issue that is closely connected to biology, technology, and society?

Accepted Answer

Climate change resulting from technological advances and population growth.

Question 19

Which of the following best explains why scientific discoveries can lead to the development of new technologies?

Accepted Answer

Understanding natural phenomena can provide insights that are applied to solve practical problems.

Question 20

A scientist is investigating the evolutionary relationship between the red panda and other species. Which type of evidence has most recently influenced the classification of the red panda?

Accepted Answer

Comparisons of DNA sequences.
