Question 1

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

Accepted Answer

Emergent properties are features that arise from the arrangement and interaction of parts within a system, and are not present in the individual components.

Question 2

A scientist observes that a certain plant species grows faster in sunlight than in shade. She hypothesizes that light intensity affects growth rate. Which of the following is the best example of a testable prediction based on her hypothesis?

Accepted Answer

If plants are exposed to higher light intensity, then they will grow taller than plants in low light.

Question 3

Which of the following is NOT a property of life as defined by biologists?

Accepted Answer

Ability to photosynthesize

Question 4

In a controlled experiment testing the effect of fertilizer on plant growth, which is the dependent variable?

Accepted Answer

Growth of the plant (e.g., height or biomass)

Question 5

Which of the following statements about scientific theories is TRUE?

Accepted Answer

A scientific theory is broader in scope than a hypothesis and supported by a large body of evidence.

Question 6

Which domain includes organisms that have membrane-bound organelles?

Accepted Answer

Eukarya

Question 7

Which of the following best illustrates the concept of negative feedback in biological systems?

Accepted Answer

When blood sugar rises, the pancreas secretes insulin, which lowers blood sugar levels.

Question 8

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

Accepted Answer

The structure of a biological component gives clues about its function.

Question 9

Which of the following is an example of inductive reasoning in biology?

Accepted Answer

All observed swans are white; therefore, all swans are white.

Question 10

Which of the following best explains why a hypothesis must be falsifiable?

Accepted Answer

So that it can be tested and potentially shown to be incorrect by evidence.

Question 11

Which of the following is the correct order of levels of biological organization from most inclusive to least inclusive?

Accepted Answer

Biosphere, ecosystem, community, population, organism, organ system, organ, tissue, cell, organelle, molecule

Question 12

Which of the following is an example of a real-world application of the scientific method?

Accepted Answer

A doctor tests whether a new drug lowers blood pressure by giving it to one group of patients and not to another, then measuring their blood pressure.

Question 13

Which of the following statements about DNA is correct?

Accepted Answer

DNA contains genes, which are units of inheritance that transmit information from parents to offspring.

Question 14

Which of the following best describes the difference between qualitative and quantitative data?

Accepted Answer

Qualitative data are descriptions, while quantitative data are numerical measurements.

Question 15

Which of the following is an example of positive feedback in biological systems?

Accepted Answer

The release of oxytocin increases the intensity and frequency of uterine contractions during childbirth.

Question 16

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

Accepted Answer

Science is concerned with understanding natural phenomena, while technology applies scientific knowledge for practical purposes.

Question 17

A researcher wants to test the effect of a new fertilizer on tomato plant yield. She sets up two groups: one receives the fertilizer, and the other does not. She keeps all other conditions the same. What is the control group in this experiment?

Accepted Answer

The group that does not receive the fertilizer

Question 18

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

Accepted Answer

Bacteria and Archaea are both prokaryotic domains.

Question 19

Which of the following best explains why scientific research must be both valid and reliable?

Accepted Answer

So that research answers the intended question and can be consistently reproduced.
