Identifying Virus Characteristics from Table Rows

Steps:

• Recall key virus traits: acellular, obligate parasites, contain nucleic acid in protein coat, replicate only in host cells.
• Match traits to table columns (e.g., living/non-living, independent reproduction, genetic material, host-dependent).
• Evaluate each row's ✓/× pattern against these traits.
• Select row aligning all virus properties correctly.

Why B is correct:

• Row B (✓ × ✓ ×) matches viruses as non-cellular (✓), unable to reproduce independently (×), possessing genetic material (✓), and requiring hosts (× for independence).

Why the others are wrong:

• A mismatches by incorrectly marking independent reproduction (✓) and host dependence (✓).
• C incorrectly indicates cellular structure (✓) and independent reproduction (× but flipped).
• D fails all traits, showing no matches (× × × ×).

Not enough information on exact table columns, but based on standard biology definitions.

Final answer: B
