normal flora are a common source of infection.
true
false
question 7 (1 point)

Explanation:

• For Question 5: Viruses lack the machinery to reproduce on their own. They must enter a host cell (intracellular) to use the host's resources for replication. So, they are obligate intracellular organisms.
• For Question 6: Normal flora can become a source of infection. For example, when the immune system is compromised (e.g., in immunocompromised patients) or when normal flora move to a site where they do not usually reside (e.g., Escherichia coli from the gut moving to the urinary tract causing a urinary - tract infection).

Answer:

Question 5: A. True
Question 6: A. True
