It would be A. That’s the point of a flu shot. U inject the virus to make your body know it’s bad and when It comes along again to fight it hard.
The answer is A, and this is true because trauma can not be transmitted or caught by humans or animals but a virus , faulty nutrition & congenital defects can. hope this helps :)
Answer:
Abiotic components of an ecosystem are water, air, light, soil, and temperature.
Now think about how the availability of these things will affect what could live in a specific area.
Consider a desert ecosystem. Deserts are arid, receiving little rain (water) and have extreme temperatures (both cold and hot). Because of these conditions only certain plants and animals can live here. These plants and animals have adaptations that are specific to the environment. If you were to put an organism that does not belong in there, they would most likely die out.
Tidbit for you. The Atacama desert is one of the driest places in the world, located specifically in Chile. At one point, this place did not receive any rain for 500 years! Still plants and animals are able to live in this area. When it finally did rain, the sudden downpour caused a radical change in this ecosystem. You would think at first rain would be good, but no. Because the changes the rain brought was too drastic, it caused a devastating effect on the organisms that lived there because they were not adapted to rain.
C, you have genes/allels that you got from your parents, but the combination of all your genes together is unique.
