Question 1

Which of the following best describes 'emergent properties' in biological systems?

Accepted Answer

Properties that arise from the arrangement and interaction of parts within a system, not present in the individual components.

Question 2

A patient with type 1 diabetes cannot produce insulin. Which biological theme does the body's response to high blood glucose illustrate?

Accepted Answer

Feedback regulation within biological systems

Question 3

Which of the following is an example of the central dogma of molecular biology?

Accepted Answer

DNA is transcribed into RNA, which is then translated into protein.

Question 4

Which of the following best explains why water is considered an emergent property of hydrogen and oxygen?

Accepted Answer

Water has properties, such as cohesion and high specific heat, that are not present in hydrogen or oxygen alone.

Question 5

Which of the following scenarios best illustrates the concept of 'descent with modification'?

Accepted Answer

A population of finches develops different beak shapes over generations as they adapt to different food sources.

Question 6

Which of the following is NOT a characteristic of scientific inquiry?

Accepted Answer

Relying on untestable ideas and personal beliefs.

Question 7

A scientist observes that plants in sunlight grow faster than those in the shade. She hypothesizes that light increases the rate of photosynthesis. Which step of the scientific method is she demonstrating?

Accepted Answer

Formulating a hypothesis based on observations.

Question 8

Which of the following best describes the relationship between structure and function in biology?

Accepted Answer

The shape and arrangement of biological structures determine their function.

Question 9

Which equation best represents the process of photosynthesis in plants?

Accepted Answer

$$6CO_2 + 6H_2O + light \rightarrow C_6H_{12}O_6$ + 6O_2$$

Question 10

Which of the following is an example of feedback regulation in the human body?

Accepted Answer

The pancreas secretes insulin in response to high blood glucose, lowering glucose levels.

Question 11

Which of the following best explains why evolution is considered the core theme of biology?

Accepted Answer

It explains both the unity and diversity of life through common ancestry and adaptation.

Question 12

Which of the following is a real-world example of the transfer and transformation of energy in an ecosystem?

Accepted Answer

Plants convert sunlight into chemical energy, which is then consumed by animals.

Question 13

A researcher is studying the effect of a new drug on cell division. She uses a control group and an experimental group. Which aspect of scientific inquiry is she demonstrating?

Accepted Answer

Using testable ideas and controlled experiments.

Question 14

Which of the following best describes the role of producers in an ecosystem?

Accepted Answer

They convert energy from sunlight into chemical energy through photosynthesis.

Question 15

Which of the following is an example of how interactions with the environment can drive evolution?

Accepted Answer

A population of insects develops resistance to a pesticide over several generations.

Question 16

Which of the following is a correct statement about the three domains of life?

Accepted Answer

They are Bacteria, Archaea, and Eukarya.

Question 17

Which of the following best illustrates the concept of 'unity and diversity of life'?

Accepted Answer

Different species share common cellular structures but have unique adaptations.

Question 18

A student claims that science can answer all questions, including those about supernatural phenomena. Which aspect of the nature of science does this statement ignore?

Accepted Answer

Science focuses on the natural world and testable ideas.

Question 19

Which of the following best describes the process of natural selection?

Accepted Answer

Individuals with traits that enhance survival and reproduction are more likely to pass on their genes to the next generation.

Question 20

Which of the following is an example of how feedback regulation maintains homeostasis in the human body?

Accepted Answer

When body temperature rises, sweat glands are activated to cool the body down.
