Dynam- denotes which?

Dynam- denotes which?

• A. Change
• B. Power
• C. Hair
• D. Odor

Answer: (B)

The main idea here is recognizing the meaning carried by a common medical root. The root dynam- comes from a Greek word for power or force. That makes it the building block used when talking about strength, energy, or force in the body or in devices that measure power. So words like dynamic, dynamometer, and dynamo all convey the sense of power or force. That’s why this is the best choice: it matches the idea of power and strength, not change, not hair, and not odor. Change would be suggested by roots like morph- or chrom-, hair by tricho- or pil-, and odor by osmo- or olfact- instead.
