a prevents all types of hpv.
b cures cancer caused by hpv.
c protects against only four types of hpv.
d eliminates the virus from the body.

question 13 (1 point)
hiv spreads through
a unbroken skin.
b transfer of infected blood.
c objects with dried blood
d body fluids from nasal membranes

Explanation:

• For Question 12: The HPV vaccine does not prevent all types of HPV (there are many types), it does not cure HPV - related cancer (it is for prevention), and it does not eliminate the virus from the body. Some vaccines like the quadrivalent HPV vaccine protect against four types (types 6, 11, 16, 18).
• For Question 13: HIV cannot spread through unbroken skin. Dried blood does not pose a risk as the virus is not viable. Body fluids from nasal membranes are not a common mode of transmission. HIV spreads through transfer of infected blood (e.g., sharing needles, blood transfusions in some cases before proper screening).

Answer:

Question 12: C. protects against only four types of HPV.
Question 13: B. transfer of infected blood.
