Answer:
Most organisms cannot obtain nitrogen from the atmosphere. Nitrogen fixing bacteria take Nitrogen out of the atmosphere and make it available for consumption by the other organisms, This is important because Nitrogen is an essential building block of life.
Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.
Earth's service would be bare. There would no longer be life and all water ways would become dried up due to the intense ultra-violent rays of the sun.
Blood type is not a concern when transfusing plasma from person to person because the plasma does not contain red blood cells. when things such as organs or blood are given to people (contain red blood cells), they must match the blood type of the person receiving these things so that there is a smaller chance of the person rejecting the organs, blood, etc. due to plasma not having red blood cells, we do not need to worry about the body rejecting it.
