The passage of IgG antibodies from mother to fetus illustrates passive immunity.
- Antibodies produced outside the body can protect a person from contracting a disease, or they can give passive immunity.
- Because antibodies are not regenerated as frequently as they would be in a person with a functioning immune system, passive immunity is typically transient.
- Immunity that is transferred from mother to kid is known as maternal passive immunity or natural passive immunity.
- Antibodies are transferred to the unborn child by the placenta while they are still in the womb and can offer protection against the corresponding infections in the weeks and months after delivery.
- An infant's passive immunity to disease is maintained after birth due to antibodies contained in breast milk, particularly in colostrum, the protein-rich milk produced in the first few days after birth.
- The importance of maternal passive immunity for safeguarding infants until their own immune system is mature enough to protect them.

Answer:
Pulmonary artery
Explanation:
The pulmonary artery delivers oxygen poor blood to the lungs that comes from the right ventricle of the heart. The pulmonary artery is also the only artery in the body that carries unoxugenated blood. When the blood goes to the lungs, it picks up oxygen and drops off carbon dioxide to be expelled from the body. The pulmonary vein then takes the oxygen-rich blood and brings it back to the heart.
Respuesta:
B. pastoreo excesivo de animales de granja
Porque son lugares secos.
Explicación:
Las políticas e infraestructuras que promueven la agricultura en las tierras de pastoreo que no pueden mantener sistemas viables de cultivo, contribuyen a la desertificación. La mayoría de las áreas de tierras secas (el 65%) son tierras de pastoreo que son más adecuadas para el pastoreo sostenible que para el cultivo.
