Question

which can modern taxonomy do?
○ design tables based on physical characteristics
○ compare the length of dna among members of a species
○ compare the length of rna among members of a species
○ distinguish how closely related organisms are

Explanation:

Modern taxonomy uses various methods (like molecular analysis, morphological, etc.) to determine evolutionary relationships. Option A: Traditional taxonomy used physical traits, modern goes beyond. Option B: Taxonomy isn't about comparing DNA length within a species (more about relationships between groups). Option C: Similar to B, not about RNA length within a species. Option D: Modern taxonomy (with molecular, phylogenetic tools) distinguishes relatedness of organisms.

Answer:

D. distinguish how closely related organisms are
