HIV is classified as?
Correct answer: B. Retrovirus
- A. Bacteriophage
- B. Retrovirus
- C. Hepatitis
- D. Icosahedral virus
Explanation
Option B is correct. Retroviruses use RNA as their genetic material and employ reverse transcriptase to form DNA, which integrates into the host genome for replication. HIV is a classic example. In contrast, bacteriophages infect bacteria, hepatitis is liver inflammation often caused by viruses (A-E), and icosahedral viruses have a capsid with 20 triangular faces, as seen in poliovirus and adenovirus.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
