The environment in a habitat is affected by many factors. These are physical factors, nonliving ones, and biotic factors, living ones. These factors vary completely in different areas. In this essay the two places I'll be taking are the rocky shore and the inland. Though they are not far away...

Hydrogen is the first element on the periodic table. It has only one electron and one energy level. Having only one proton and one electron causes it to be very light in weight. The British scientist Henry Cavendish is given credit with discovering hydrogen in 1766, but studies show that German-Swi...
