    Both biotic and abiotic factors are responsible for the loss of stored grains. Abiotic factors include improper temperature of store house, humidity of air and high moisture content of the grains. Improper containers used for storage also cause loss of grains. Biotic factors include insect infusion, mites, birds, rodents, diseases caused by microorganisms and enzymatic actions occuring within food grains.

    The cell wall is the outermost covering of plant cells. It is present outside the cell membrane and is tough, flexible and sometimes rigid in its texture. It is mainly composed of cellulose,  long fibres of carbohydrates including hemicellulose, lignin, and pectin.

    The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane composed of lipids and proteins. The main functions of the cell membrane include:

    1. Protecting the integrity of the interior cell.

    2. Providing support and maintaining the shape of the cell.

    3. Helps in regulating cell growth through the balance of endocytosis and exocytosis.

    0Thank You

    Yogita Ingle 4 years, 4 months ago

    Acceleration

    • Acceleration: It is a measure of the change in the velocity of an object per unit time.
    • Acceleration can be caused either by change in direction of motion or change in speed or both. 
      Acceleration = Change in velocity/ time taken.
    • SI unit is ms-2.

    All layers and organs in the body are lined by a group of tissues called epithelial tissues which are commonly referred to as epithelium. They cover the surface of all internal as well as external organs. Epithelial tissue is highly permeable. Thus, it plays a significant role in the exchange of substances across the cells and helps in maintaining the osmoregulation. Depending on the number of layers of cells it is composed of, epithelium has been divided into simple epithelium and compound epithelium. The main functions of epithelial tissue are protection, secretion, absorption, and sensation.

    The reverse process of sublimation is <a href="https://en.wikipedia.org/wiki/Deposition_(phase_transition)" title="Deposition (phase transition)">deposition</a> or desublimation, in which a substance passes directly from a gas to a solid phase. Sublimation has also been used as a generic term to describe a solid-to-gas transition (sublimation) followed by a gas-to-solid transition (<a href="https://en.wikipedia.org/wiki/Deposition_(phase_transition)" title="Deposition (phase transition)">deposition</a>).

     While a transition from liquid to gas is described as <a href="https://en.wikipedia.org/wiki/Evaporation" title="Evaporation">evaporation</a> if it occurs below the boiling point of the liquid, and as <a href="https://en.wikipedia.org/wiki/Boiling" title="Boiling">boiling</a> if it occurs at the boiling point, there is no such distinction within the solid-to-gas transition, which is always described as sublimation.

    The term <i>sublimation</i> refers to a <a href="https://en.wikipedia.org/wiki/Physical_change" title="Physical change">physical change</a> of <a href="https://en.wikipedia.org/wiki/State_of_matter" title="State of matter">state</a> and is not used to describe the transformation of a solid to a gas in a chemical reaction. For example, the dissociation on heating of solid <a href="https://en.wikipedia.org/wiki/Ammonium_chloride" title="Ammonium chloride">ammonium chloride</a> into hydrogen chloride and ammonia is <i>not</i> sublimation but a chemical reaction. Similarly the combustion of candles, containing <a href="https://en.wikipedia.org/wiki/Paraffin_wax" title="Paraffin wax">paraffin wax</a>, to <a href="https://en.wikipedia.org/wiki/Carbon_dioxide" title="Carbon dioxide">carbon dioxide</a> and <a href="https://en.wikipedia.org/wiki/Water_vapor" title="Water vapor">water vapor</a> is <i>not</i> sublimation but a chemical reaction with oxygen.

    Sublimation is caused by the absorption of heat which provides enough energy for some molecules to overcome the <a href="https://en.wikipedia.org/wiki/Intermolecular_force" title="Intermolecular force">attractive forces</a> of their neighbors and escape into the vapor phase. Since the process requires additional energy, it is an <a href="https://en.wikipedia.org/wiki/Endothermic" title="Endothermic">endothermic</a> change.

    Condensation is the process by which water vapor in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapor, from your hot shower cooled when it met the surface of the cold mirror. This caused the water vapor to condense, or turn into its liquid form. You notice it as moisture or beads of water and fog that has formed on the mirror.

    Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.
