Question

question 32 (1 point)
which bacterium causes tuberculosis?
○ streptococcus pneumoniae
○ mycobacterium tuberculosis
○ staphylococcus aureus
○ eschericia coli
question 33 (1 point)
newborns immunity due to the transfer of antibodies across the placenta is an example of
○ naturally acquired passive immunity
○ artificially acquired active immunity
○ naturally acquired active immunity
○ innate rimmunity

Explanation:

Question 32

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. Streptococcus pneumoniae causes pneumonia, Staphylococcus aureus causes various infections like skin infections, and Escherichia coli is associated with gut - related issues or other infections but not tuberculosis.

Naturally acquired passive immunity occurs when antibodies are transferred from one individual to another without the recipient's immune system actively producing them. In the case of newborns, antibodies from the mother cross the placenta, so it is naturally acquired (happens in the natural process of pregnancy and birth) and passive (antibodies are transferred, not the newborn's immune system actively making them). Artificially acquired active immunity is from vaccines, naturally acquired active immunity is from getting an infection, and innate immunity is non - specific and present at birth (not related to antibody transfer).

Answer:

B. Mycobacterium tuberculosis
