Accepted Answer

Ability to photosynthesize

Question 4

Which statement best explains why hypotheses must be testable?

Accepted Answer

So that experiments can be designed to support or refute them using empirical evidence.

Question 5

A researcher is studying the effect of a new drug on blood pressure. She gives the drug to one group and a placebo to another. What is the purpose of the placebo group in this experiment?

Accepted Answer

To serve as a control group for comparison

Question 6

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

Accepted Answer

A population of finches develops different beak shapes over generations due to changes in available food sources.

Question 7

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

Accepted Answer

Predicting that all mammals have kidneys because you know that mammals are defined as animals with kidneys.

Question 8

Which of the following best describes the role of technology in science?

Accepted Answer

Technology provides tools that allow scientists to collect data and test hypotheses more effectively.

Question 9

Which of the following is the correct sequence of the ten levels of biological organization from smallest to largest?

Question 10

Which of the following best explains why science is considered a social activity?

Accepted Answer

Scientific progress depends on collaboration, peer review, and sharing of ideas among scientists.

Question 11

A biologist is using bioinformatics to analyze genetic data. Which of the following best describes bioinformatics?

Accepted Answer

The use of computational tools to store, organize, and analyze large volumes of biological data.

Question 12

Which of the following is a key difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells contain membrane-bound organelles, while prokaryotic cells do not.

Question 13

Which of the following best describes the function of a genome?

Accepted Answer

Accepted Answer

Temperature

Question 15

Which of the following best explains the importance of Darwin's theory of evolution to biology?

Accepted Answer

It provides a unifying explanation for the diversity and unity of life.

Question 16

Question 17

Which of the following best describes the cell theory?

Accepted Answer

All living things are composed of cells, and all cells come from pre-existing cells.

Question 18

A student is analyzing the transfer of energy in an ecosystem. Which of the following statements is correct?

Accepted Answer

Energy flows through an ecosystem, entering as light and exiting as heat.

Question 19

Which of the following is a reason why variables and controls are important in scientific experiments?

Accepted Answer

They allow scientists to isolate the effect of the independent variable and ensure reliable results.

Question 20

Which of the following best describes the difference between a hypothesis and a theory in science?

Accepted Answer

A hypothesis is a testable explanation for a specific observation, while a theory is a broad explanation supported by a large body of evidence.
