Question

what technique is used to provide insights to the evolutionary relationship between nematodes? dna sequencing distillation litmus test

Explanation:

To determine the technique for studying nematode evolutionary relationships, we analyze each option:

• DNA Sequencing: Compares genetic material (DNA) of organisms. Evolutionary relationships are inferred from genetic similarities/differences. Nematodes’ DNA sequences can show how closely related they are.
• Distillation: A chemical separation process (e.g., separating liquids), irrelevant to evolutionary biology.
• Litmus Test: Determines acidity/alkalinity, unrelated to evolution.

Thus, DNA Sequencing is the correct technique.

Answer:

A. DNA Sequencing
