Question

question 11 (1 point)
which of the following is not a reservoir of infection?
o a sick person
o none of these, all can be reservoirs
o a hospital
o a healthy person
o a sick animal
question 12 (bonus) (1 point)
which of the following is not a characteristic of viruses?
o they have either dna or rna as their genetic material.
o they can cause disease in humans, animals, and plants.
o they are acellular.
o they can replicate independently outside of a host cell.

Explanation:

• For Question 11: Reservoirs of infection are sources where pathogens can live, grow, and multiply. A sick person, a hospital (as it can harbor pathogens), a healthy person (can be a carrier), and a sick animal can all be reservoirs. So the answer is "none of these, all can be reservoirs".
• For Question 12: Viruses have either DNA or RNA as genetic material, are acellular, and can cause disease. But they cannot replicate independently outside of a host cell.

Answer:

Question 11: none of these, all can be reservoirs
Question 12: They can replicate independently outside of a host cell.
