Question

question 42 (1 point)
a pathogen is best defined as:
a microbe that causes disease
any microbe
a mutualistic organism
a harmless commensal
question 43 (1 point)
virulence refers to:
the degree of pathogenicity
the resistance to antibiotics
the ability to form spores
the hosts immune response

Explanation:

• Question 42: A pathogen is specifically a microbe that causes disease. Not all microbes are pathogens (e.g., some are harmless commensals or mutualistic organisms).
• Question 43: Virulence is defined as the degree of pathogenicity. Resistance to antibiotics, ability to form spores, and the host's immune response are not the definitions of virulence.

Answer:

• Question 42: A. A microbe that causes disease
• Question 43: A. The degree of pathogenicity
