Sample Questions and Their Correct Answers (2020)
Multiple Choice Sample
Question: Which organelle is primarily responsible for energy production in the cell?
- A) Nucleus
- B) Mitochondria
- C) Ribosome
- D) Chloroplast
Answer: B) Mitochondria
Constructed-Response Sample
Question: Explain how natural selection can lead to the evolution of a population over time.
Sample Answer: Natural selection occurs when organisms with advantageous traits are more likely to survive and reproduce. Over generations, these traits become more common in the population. This process can lead to evolutionary changes as the frequency of beneficial traits increases, resulting in adaptation to the environment.
