Answer:
In the first diagram the weakened pathogen (weaker version of the disease) is inserted into the bloodstream.
In the second diagram the antibodies kill the weakened pathogen. When the immune systems encounters a new disease it "remembers it".
This is why in the third diagram, when the "real" pathogen enters the bloodstream the immune system can effectively kill the disease. As the immune system "remembers" how to defeat the weakened version it can more effectively kill the "real" version.

Hello!
Jet streams are large currents of air that travel around the planet. The ocean does not control the wind. The Sun does not control the wind. Hurricanes do not either. Mountain breezes can influence and are influenced by the jet stream.
I hope this helps!

C. The small crowd of protesters had turned into an angry mob.
Explanation:
The direction iron in ocean rocks points
The new crust, formed at constructive/divergent boundary (regarding tectonic plate movement), has band-like patterns that orient in different directions (in alignment with earth's magnetic fields) and visible on the surface. This shows that it is newly made crust made from new magma.
Explanation:
These bands are firmed when the iron minerals in magma orient themselves with the earth's magnetic field before the magma cols into rock and lock the minerals permanently in position. This magma upwells from the mantle to fill the void made when the tectonic plates are moving away from each other.
The earth's magnetic field on the other hand is dynamic. Its angle increases gradually from the true north or south and then flips orientation over several hundred years. The iron minerals therefore will align differently depending on the orientation of the earths magnetic field at the time. This is why the new crust has band-like features visible on its surface.
