Y CHROMOSOME

Y CHROMOSOME

 The Y chromosome is one of the two sex chromosomes in humans (the other is the X
chromosome).
 The sex chromosomes form one of the 23 pairs of human chromosomes in each cell.
 The Y chromosome is present in males, who have one X and one Y chromosome.
 Sex is determined by the SRY gene on the Y chromosome, which is responsible for the
development of a fetus into a male.
 Other genes on the Y chromosome are important for male fertility. Many genes are unique to the
Y chromosome.
 Genes present in areas known as pseudoautosomal regions take part in pairing during meiosis.

Soils of India (Geography Project)

è Introduction Soil is the mixture of minerals, organic matter, gases, liquids and a myriad of organisms that can support plant life. It is a natural body that exists as part of the pedosphere and it performs four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of the atmosphere; and it is a habitat for organisms that take part in decomposition and creation of a habitat for other organisms .Soil is considered the "skin of the earth" with interfaces between the lithosphere, hydrosphere, atmosphere, and biosphere. Soil consists of a solid phase (minerals and organic matter) as well as a porous phase that holds gases and water. Accordingly, soils are often treated as a three-state system .Soil is the end product of the influence of the climate, relief (elevation, orientation, and slope of terrain), biotic activities (or...

Astronomy

                                           Astronomy  (from  Greek : αστρονομία) is a  natural science  that studies  celestial objects  and phenomena. It applies  mathematics ,  physics , and  chemistry , in an effort to explain the origin of those objects and phenomena and their  evolution . Objects of interest include  planets ,  moons ,  stars ,  galaxies , and  comets ; while the phenomena include  supernovae explosions ,  gamma ray bursts , and  cosmic microwave background radiation . More generally, all astronomical phenomena that originate outside  Earth's atmosphere  are within the purview of astronomy. A related but distinct subject,  physical cosmology , is concerned with the study of the  Universe  as a whole. [1] Astronomy is the oldest of the natur...
