200 A Industrial fuse. 80 kA breaking capacity. In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit including the source of power and the load.
In order for natural selection to operate on a trait, the trait must possess heritable variation and must confer an advantage in the competition for resources. If one of these requirements does not occur, then the trait does not experience natural selection.
Describe the theory of evolution by natural selection. Natural selection occurs when environmental conditions select for certain advantageous traits. Because traits are heritable, the traits of those who successfully reproduced are more common in the next generation. And in this way, nature selects for these traits. Evolution by natural selection is thus the change in the frequency of different alleles for a trait through time. Over time, natural selection can allow species to adapt to changing environmental conditions and diverge from one another, leading to the great diversity of form and function of organisms we observe today.
