When talking about infectious disease , what is a carrier ?

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.

for respect usually. some people might be little awkward if you meet or some would be different. usually   you dont love people when you meet them depends on the type of person.

hope this
