Zebra mussels will take over an ecosystem and deplete resources that species indigenous to the area require to survive.
They are NOT photosynthetic
The rabies virus spread through animals and cause deadly effects. The influenza virus is easily passed between humans and is easily treatable and much less deadly.
A hot spot is here magma appears near to the surface. Imagine this, the crust is a plate, and the hotspot is a pencil, as the plate moves, you punch holes through the plate. This is the hotspot creating volcanoes as the crust moves. This is how hotspot volcanoes are created. The volcanoes that are created on boundaries are created from differences in the crust as it is created.
<span> (1) gene frequencies may be changed by migration, gene flow from another population. (2) in small populations, gene frequencies can be changed via random sampling -- this is known as genetic drift. (3) mutation pressure and (4) non-Mendelian segregation (meiotic drive) may also change gene pools. However, by far the most important agent of evolution is (5) natural selection, which operates by </span>differential reproductive success<span> of individuals.
