STPM Biology - Chapter 12: Immunity Q4

Does breastfeeding a baby impart active or passive immunity?  Explain.  How long does this immunity last in the baby?

Answer
Breastfeeding a baby passes antibodies from the mother of the baby and is a form of passive immunity.  This provides temporary immunity for the first few months after which no further protection is provided.
