Answer:
A; when a new trait evolves
Explanation:
Each branch of a cladogram represents a species ending at a clade. A clade represents a group of organisms with a common ancestor. When a new trait evolves and the group is no longer the same species, it will branch off
If pathogen A is more resistant to an erythromycin disc on a Kirby-Bauer plate compared to B, then A will have a smaller zone of inhibition compared to B.
<h3>What is the zone of inhibition?</h3>
The zone of inhibition can be defined as a circular region in a plate where pathogenic agents cannot grow.
This zone (zone of inhibition) can determine the action of different drugs like antibiotics for a given disease.
The zone of inhibition test is also widely known as the Kirby-Bauer Test due to their developers.
