        Our Earth is the only known planet to sustain life in the solar system; as it is present in the habitable zone around the sun. Our Earth is gravitationally bonded to the sun which makes us revolve around our star continuously. Our earth revolves around the sun (one complete round) over a period of one year. Over this period our earth encounters various situations; among which one of the main situations is seasons.   Spring Summer      Autumn Winter           Our earth mainly encounters four seasons, namely summer, winter, spring, and autumn. These seasons are commonly called as temperate seasons. Even though there are four seasons, some locations particularly near the equatorial regions experience different seasons as the rainy season, on behalf of winter. Before knowing about each of these seasons, let’s know how these seasons occur at the first step. We know that our earth is tilted at 23.4 degrees. First of all, we cannot map a sphere where it was tilted. Because whatev

         Twins are one of the separate kinds in human birth history. As it is very rare during birth it always marks a separate place in life. Also not every twin’s looks like same. On the before topic of  fertilization , we saw what fertilization is, and how a normal baby is formed through fertilization. In a nutshell, fertilization is the process, where a sperm meets the egg, and brings a new life. But it needs to be considered, that how a sperm fertilizes the egg and how a baby is born. A baby can be born as single if only one sperm fertilizes the ovum and that ovum makes its journey without dividing.  But there are several possibilities in which fertilization can occur. Those possibilities may result in various types of twins, which are, Identical twins Non-identical twins Semi identical twins Mirror image twins Mixed chromosome twins Heteropaternal superfecundation Superfetation Turner twins Polar body twins Parasitic twins Biracial twins Vanishing twins.     Even though there a

Fertilization happens in every common species like plants, animals, and humans. But fertilization in humans is much more complicated and it is a needed one, to sustain our race. Let’s see about the process in detail. Sperm and an Ovum       Human fertilization occurs only in women , where she gives birth to a child from a single cell (ovum or egg cell) in her body. But to make the women get fertilized (i.e., to give birth to a child) a man is required , who delivers another type of cell (sperm cell) for the fertilization. So, when the sperm from the man and the ovum from the woman got fused in the woman’s body, fertilization occurs and that fusion cell develops into a full-form baby . Only the sperm can get to the women’s body
