Answer:
Passice immunity
Explanation:
Breast milk, produced by female mammals (including humans), besides being rich in fat and protein is full of IgA. IgA is the immunoglobulin (immune system signal proteins) that is present in body secretions, such as milk.
The baby that is fed from the mother's breast ingests these defense proteins that allow it to tolerate different pathogens and toxins.
It is considered passive immunity, as it does not generate memory and depends on a continuous dose to maintain defense levels.

Answer:
The endosymbiotic theory states that chloroplast originated from A Cyanobacteria entering and remaining in the cytoplasm of another cell.
Explanation:
Endosymbiotic theory in an important theory of evolution which states that Eukaryotic cells are originated from prokaryotic organism.
The theory deals with the fact that chloroplast and mitocondria were free living prokaryotic organism at Past. The similarities between prokaryotic cell and these Eukaryotic organelles(Mitocondria,Chloroplast) and the evolution of mitocondria and chloroplast from the prokaryotic cells is best exlained by the theory of endosymbiosis.
Mitocondria evolved from the Endocytosis of aerobic bacteria,whereas Choroplast are originated from photosynthetic bacteria such as cyanobacteria.

Answer: Sympathetic
The alarm reaction to danger that is triggered by anxiety primarily involves the sympathetic nervous system
Explanation:
The sympathetic nervous system (SNS) primarily stimulates many parts of the body for action in times of danger or emergency situations.
During this process, a hormone known as adrenaline (the emergency hormone) would be released, and effects such as sweating, increased heartbeat, raised blood pressure will follow.
