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.

There are three domains, and six kingdoms.
Vacuole is not a structure used for cellular movement
Answer:
Option B, Rr pp × rr Pp
Explanation:
Given
Walnut Comb is produces when one dominant allele R is present at one gene locus and at least one dominant allele P is present at a second gene locus - R* P*
Rose Comb - at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus - R* pp
Pea comb - two recessive alleles are present at the first locus and at least one dominant allele is present at the second - rr P*
Single comb - two recessive alleles are present at the first and the second locus - rrpp
Parent are rose combed and pea combed
For being rose genotype must be R* pp
and for being pea combed genotype must be rr P*
Rr pp x rr Pp
will produce
Walnut comb with genotype Rr Pp
Single comb with genotype rrpp
and pea comb with genotype rrPp
Hence, option B is correct
Answer:
a) During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.
