Why do the navajo associate the tips of the fingers with the trail of the wind?
kozerog [31]
Allegedly, <span>the finger tips show where the wind blew when our ancestors were created. In a way, their fingertips are roots to their ancestors, so touching them somehow links them to their ancestors. And as you probably know, the Navajo are very much connected to their ancestors, and tribes in general. </span>

Answer:

<u>Passive immunity</u> is passed from a mother’s breast milk to her nursing infant.

Anne Marie recently had a baby girl. She has read all about the benefits of breastfeeding her newborn. Anne Marie knows that her milk can help keep her newborn from contracting a disease. She talks with the baby’s pediatrician, who confirms that the infant will receive temporary Passive Immunity from antibodies transferred in Anne Marie’s breast milk.

Explanation:

Passive immunity can be described as a kind of immunity in which a person gets immunity or antibodies from another source rather than his/her own body producing the immune cells. Active immunity can be described as an immunity which is triggered by a person's own immune cells.

In infants, mothers pass on antibodies to the child by breastfeeding. Hence, it is a type of passive immunity. Passive immunity cannot be as long-lasting as active immunity. It only lasts for some weeks.
