I know that one of them is respiratory system.....
Answer:
For the third line of defense is the line that is responsible for the formation of antibodies and acquired immunity that affects the immunological memory.
Explanation:
Antibodies or immunological memory is formed thanks to antigen-presenting cells that engulf the antigen or pathogen, exposing its characteristic molecule on the surface, so that the lymphocyte lineage can reproduce an antibody in relation to that specific molecule, forming as produces a specialized antibody to a particular antigen for subsequent contact with it.
Immunology has three barriers or three lines, the first is the rapid response, cell filtration, pyocytes and neutrophil nuclear polymorphs that seek to destroy the antigen, these when undergoing cell death make up a collection of pyocytes that are known as purulent collection.
The second line is phagocytosis by APCs or antigen presenting cells, rich in the release of chemical mediators, multinucleated, with large lysosomal systems that digest the antigen.
And the last line, is the lymphocyte, where it is sought to form a specific antibody, it seeks a lymphocytic recruitment already matured in the nodes, that is why it takes longer, because it takes more energy and time for our immune system, in addition They depend on the compliance and proper functioning of the first two lines of defense.
Answer:
★ People's awareness of the environmental changes brought about by industrialization
Explanation:
Hope you have a great day :)
The best answer would be:
The first option.
Air moves in a direction that creates land breezes.
If you'd like to know more about this, you can read on:
The arrows show how air moves as land breezes are created. In coastal areas, land cools much faster than water, so what happens is the air above it gets cooled down. When this happens, it becomes more dense moves downwards towards land. This causes high pressure and cause winds to blow outwards towards water (ocean).
B) Circulatory.
The Circulatory system spreads the blood all around the heart. It makes sure blood is able to reach every part in the body.
