Eukaryotes, including plants, animals, fungi, and protists, have more complex cell

organization. Recognizing these differences helps in understanding cellular function and

evolution.

4. How does DNA differ from RNA?

Answer: DNA contains the sugar deoxyribose, is double-stranded, and stores genetic

information; RNA contains ribose sugar, is usually single-stranded, and plays roles in

protein synthesis.

Explanation: DNA (deoxyribonucleic acid) holds the hereditary blueprint for organisms,

while RNA (ribonucleic acid) acts as a messenger and translator in the process of making

proteins. Knowing the structural and functional differences is key in genetics and

molecular biology.

5. What is natural selection?

Answer: Natural selection is the process where organisms better adapted to their

environment tend to survive and reproduce, passing advantageous traits to the next

generation.

Explanation: Proposed by Charles Darwin, natural selection explains how species evolve

over time. It’s fundamental to understanding biodiversity and evolutionary biology.
