Various organ systems of the Human Body are discussed in this article which not only enhance your knowledge and ease your exam preparation but also help to understand the phenomena of our body.
The Sun is the star at the centre of the solar system. It is mainly composed of hydrogen and helium. There are various solar missions launched by observatories to study high resolution and close-up view of Sun and its inner heliosphere (the innermost region of our Solar System) to predict and to better understand the intractable or restive behaviour of the star on which our lives depend.
Biology is a natural science in which we study about the life of living organisms consisting of various functions, structure, evolution, taxonomy etc. and is composed of many branches through which the scope of biology is broadened with the unifying concepts that govern all study and research which is consolidated into a single and coherent field.
In contemporary world there have been undergone tremendous expansions of Biological Sciences such as Cell Biology, Neuroscience and Evolutionary Biology through the advancement of various inventions and discoveries that not only improved the quality of living but also increases life expectancy.

Nuclear fission and nuclear fusion are two types of nuclear reactions. Fission means to split and fusion means to combine. Therefore in fission reaction a heavy nucleus of atom is bombarded so that it splits and in fusion reaction two lighter nuclei are heated at high temperature so that they combine to form a heavy nucleus.
The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion. It is interesting to know why the level of mercury rises with temperature, wires attached to electric poles contract or expand with change in season, etc. This all is due to thermal expansion.
