Evolution

Question 4

Which of the following is a key requirement for a scientific hypothesis?

Accepted Answer

It must be testable and falsifiable.

Question 5

Which of the following best illustrates the theme of 'Energy and matter' in biology?

Accepted Answer

Question 6

In the case study of mice camouflage, what was the main purpose of using model mice in different habitats?

Accepted Answer

To test the hypothesis that fur color affects predation rates.

Question 7

Which of the following statements about scientific theories is correct?

Accepted Answer

Theories make sense of a large amount of data and are self-correcting.

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

Accepted Answer

The regulation of blood glucose levels by insulin.

Question 9

Which of the following best describes the difference between reductionism and systems biology?

Accepted Answer

Deductive reasoning

Question 15

Which of the following is a correct statement about the relationship between chemistry, physics, and biology?

Accepted Answer

Biology is fundamentally based on chemistry, which is based on physics, which is based on math.

Question 16

A student claims that a hypothesis can be proven true if enough experiments support it. Which concept from the scientific method contradicts this claim?

Accepted Answer

Hypotheses are never proven, only supported or contradicted.

Question 17

Which of the following is an example of the theme 'Interactions' in biology?

Accepted Answer

The fight-or-flight response triggered by adrenaline.

Question 18

Which of the following best describes the difference between basic and applied research?

Accepted Answer

Basic research seeks to expand fundamental knowledge, while applied research aims to solve practical problems.

Question 19

Which of the following is a correct example of a testable and falsifiable hypothesis?

Accepted Answer

"If plants are given more sunlight, then they will grow taller."

Question 20

Which of the following best explains why the scientific method is considered self-correcting?

Accepted Answer

Because new evidence can lead to the revision or rejection of previous hypotheses and theories.
