Show answer & explanation
Correct answer: C — It allows for the study of relationships and correlation between organisms
Classification helps biologists organize living things based on their relationships, allowing them to study similarities and differences and infer evolutionary relationships.
Q3. If we classify organisms based on shared characteristics, we are primarily focusing on which aspect of biology?
Show answer & explanation
Correct answer: B — Systematics
Systematics is the branch of biology concerned with the classification of organisms and the study of their evolutionary relationships.
Q4. Which of the following terms refers to the variety of life existing in a particular habitat or region?
Show answer & explanation
Correct answer: D — Species diversity
Species diversity refers to the variety of different species present in a particular area, which is a core component of biodiversity.
Q5. The concept of a biological species generally emphasizes which of the following characteristics?
Show answer & explanation

Correct answer: D — Phylum
The standard hierarchical order in taxonomy is Kingdom > Phylum > Class > Order > Family > Genus > Species. Therefore, Phylum is the unit immediately above Kingdom.
Q10. Binomial nomenclature is primarily used for which purpose in biology?
Show answer & explanation
Correct answer: A — To provide a universal and unambiguous name for every species
The main purpose of binomial nomenclature is to provide a unique and standardized name for every species worldwide.
Q11. The broadest category in the taxonomic hierarchy is:
Show answer & explanation

Q15. Which of the following represents the broadest category in the taxonomic hierarchy?
Show answer & explanation
Correct answer: B — Kingdom
