Energy is the capacity to do work, and it exists in various forms. Some of its forms are: nuclear energy, solar energy, electrical energy, mechanical energy, sound energy, light energy, heat/ thermal energy etc. These forms can be transformed from one to another. Example is the conversion of electrical energy into light energy and heat energy by an electrical Tungsten-bulb.
A space heater is an electrical device used for generation of majorly heat energy, thus it is powered by electrical energy. Therefore it transforms electrical energy into electromagnetic and thermal.

The Theories of Organic Evolution explains convincing the origin of life. It also explains how the wide variety of plants and animals came into existence in the world. According to this theory, the world has been evolved and not been created.
Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
