    Liver is the largest gland in the human body. A human liver normally weighs 1.44--1.66 kg. It is both the heaviest internal organ and the largest gland in the human body. It is also one of the most important organs. In addition to being an accessory digestive organ, it plays a number of roles in metabolism and regulation. The liver lies inferior to the diaphragm in the right upper quadrant of the abdominal cavity and receives protection from the surrounding ribs.

    0Thank You

    Yogita Ingle 7 years, 3 months ago

    Organelles in cell biology could be termed as the subunit within a cell that is dedicated to performing a specific function. Individual organelles are encompassed within their own lipid bilayers. In simple terms, it is the membrane-bound structure that is present within a cell. Cell fractionation is the process performed to purify cell organelles.

    The cathode is the electrode where the electrochemical reduction reaction occurs. The anode is that where the electrochemical oxidation reaction occurs. The electroplating process uses an anode and a cathode. In electroplating, the metal dissolved from the anode can be plated onto the cathode. The part to be plated is the cathode of the circuit. In one technique, the anode is made of the metal to be plated on the part. Both components are immersed in a solution called an electrolyte containing one or more dissolved metal salts as well as other ions that permit the flow of electricity.

    Biogas is a mixture of methane, carbon dioxide, hydrogen and hydrogen sulphide. The major constituent of biogas is methane.
    Biogas is produced by the anaerobic degradation of animal wastes like cow-dung or plant wastes in the presence of water.
    The biogas plant has a dome-like structure built with bricks. A slurry of cow-dung and water is made in the mixing tank from where it is fed into the digester. The digester is a sealed chamber in which there is no oxygen. Anaerobic micro-organisms that do not require oxygen decompose or break down complex
    compounds of the cow-dung slurry. It takes a few days for the decomposition process to be complete and generate gases. The biogas is stored in the gas tank above the digester from which they are drawn through pipes for use.

    Food preservation

    0Thank You

    Yogita Ingle 7 years, 3 months ago

    When a food item is kept in plenty of salt, water from food comes out because of osmosis. It results in dehydration of the food item. Absence of moisture helps to prevent the growth of microbes. Fish, meat and pickles are preserved by adding salt. Techniques to prolong the shelf life of a food are called food preservation.

    Pluto was discovered by Clyde Tombaugh in 1930 and declared to be the ninth planet from the Sun. After 1992, its status as a planet was questioned following the discovery of several objects of similar size in the Kuiper belt. That definition excluded Pluto and reclassified it as a dwarf planet. In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of “dwarf planet.” This means that from now on only the rocky worlds of the inner Solar System and the gas giants of the outer system will be designated as planets.

    This is a chemical change because when we dip onion in vinegar it changes only coloure not its shape. Vinegar is an acid, so when you poured the indicator solution into the second flask, it turned red. Ammonia is a base, so when you mixed the acidic vinegar solution with ammonia, it raised the pH and the water turned blue.

    Deforestation is the cutting down the trees and vegetation cover.It affects the environment due to the following reasons: *The life of all the biotic species are threatened as the basic utility of our life ;oxygen cannot be obtained as trees give us oxygen. *Also the life cycle gets disturbed as many biotic species depend on trees for food. *Fewer forests means large amount of greenhouse gases released into the atmosphere. *It also disturbs the water cycle as trees release water through transpiration. *There is no stooping for soil erosions if trees are not there as they hold the soil firmly with their roots. *The normal environment due to deforestation fets polluted which imposes a great threat to the ozone layer which acts as overall defence for the earth.
