Water is known as universal solvent essential for all organisms to survive. It keeps the living organism hydrated. Water is colorless, odorless, transparent, tasteless exist gaseous, liquid, and solid states. People are confused about the water either it is mixture or compound. Water is made of two hydrogen atoms and one oxygen atom linked by covalent bonding. It is formed by reaction of hydrogen atom and oxygen atom. 2H + O → H2O Compounds are…

Summary of difference between compounds and mixtures are following which help the student for proper understanding #SrDifferential propertiescompoundsCompounds1DefinitionA compound contains atoms of different elements which can be formed by chemically combining two or more elements.A mixture is a combination of two or more substances that are formed by physically mixing two or more substances.2CompositionThe ratio of the elements in compounds are always in fixed ratio in define mannerThe components in mixtures are different elements so ratio…

Lymphocytes are the cells of the immune system that play a crucial role in immunity. They present 20% to 40% in circulating white blood cells and 99% of cells in the lymph. There are three types of lymphocytes B lymphocytes (B cells)T lymphocytes (T cells)natural killer (NK) cells B and T cells are small cells almost 8–10 microns in diameter having a large nucleus with dense hetero-chromatin. B and T cells are able to recognize…

Epithelial tissues are the thin tissue that lines the interior of hollow organs and cover exposed body surfaces such as skin the airways, the digestive tract, as well as the urinary and reproductive systems. It is one of the four types of tissues in animals. Epithelial tissue consists of epithelial cells that arrange in the continuous sheet, in either single or multiple layers that are underlain by the basement membrane. This basement membrane is the…

Centipede and millipede belong to group Myriapoda; subphylum consists of four classes of arthropods.  They are not true insects because actually they more closely related to lobsters, crayfish and shrimp. Both centipede and millipede share many characteristics as both have segmented bodies, found in moist habitats or areas with high humidity. They are active at night. Besides having many similarities, both centipedes and millipedes have many differences that make them possible to distinguish. Centipede Centipede…
