    The Constitution is needed for the following reasons:

    1. The Constitution provides a framework within which a government has to work.
    2. It controls the misuse of power by the government.
    3. It minimises the chances of disputes among the various organs of the Government as it clearly defines their powers and functions.
    4. It safeguards the fundamental rights of the citizens.

    It is the pulling force responsible for lifting the water column. As water is lost in form of water vapour to atmosphere from the mesophyll cells by transpiration, a negative hydrostatic pressure is created in the mesophyll cells which in turn draw water from veins of the leaves.
    The negative tension is then gradually transmitted downwards via xylem tissues of the leaf, stem and finally to the roots. As a result there is a continuous upward movement of water column in the plant. 1 atm. pressure can raise water to a height of more than 32ft. So a tension of 13 atm is needed to raise water to a height of 416 feet, scientist have measured this tension to be more than 75 atm. in case of trees, more than 400 feet in height.
    Thus the transpiration pull acts as pull from above on the-whole of water column of the plant which pushes the water column of xylem vessels of roots lowers leaves i.e. in an upward direction. This is how ascent of sap is affected in plants.
    The whole process can be compared to a person (transpiration pull) pulling a bucket full of water with a steel rope (unbroken and continuous water column)

    Micronutrients are needed in very small Amounts by the plants, but if their concentration decreases, then it causes deficiency symptoms and if it increases it causes toxicity. The nutrient is considered to be toxic which reduces the dry weight of tissue by about 10 percent.Nutrients that plants require in larger amounts are called macronutrients. About half of the essential elements are considered macronutrients: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.

    This method which i understood why 0!=1. Now if u want 9! U will do 10!/10,if u want 8! U will do 9!/9 similarly so on still 2!/2=1! then same way for 0!(zero factorial what u need) u will do 1!/1 hence u will get 0!=1! Which is nothing but 1. Hope understood this.there are many other way also but this one gave satisfaction to me.

    Osmosis is the process in which solvent molecules moves through a semi-permeable membrane from a region of higher concentration to a region of lower concentration until the amount of fluid is equalised on both sides of the semipermeable membrane.  

    The fluid that passes through the semipermeable membrane is known as the solvent, while the dissolved substance in the fluid is known as the solute.  The mixture of solvent and solute makes up a solution.

     

    2Thank You

    Ayushi Ayushi 7 years ago

    Osmosis is a vital process in biological systems, as biological membranes are semipermeable. In general, these membranes are impermeable to large and polar molecules, such as ions, proteins, and polysaccharides, while being permeable to non-polar or hydrophobic molecules like lipids as well as to small molecules like oxygen, carbon dioxide, nitrogen, and nitric oxide. Permeability depends on solubility, charge, or chemistry, as well as solute size. Water molecules travel through the plasma membrane, tonoplast membrane (vacuole) or protoplast by diffusing across the phospholipid bilayer via aquaporins (small transmembrane proteins similar to those responsible for facilitated diffusion and ion channels). Osmosis provides the primary means by which water is transported into and out of cells. The turgor pressure of a cell is largely maintained by osmosis across the cell membrane between the cell interior and its relatively hypotonic environment.

    In mathematics, a limit is the value that a function (or sequence) "approaches" as the input (or index) "approaches" some value.[1] Limits are essential to calculus (and mathematical analysis in general) and are used to define continuity, derivatives, and integrals. The concept of a limit of a sequence is further generalized to the concept of a limit of a topological net, and is closely related to limit and direct limit in category theory. In formulas, a limit is usually written as {\displaystyle \lim _{n\to c}f(n)=L} \lim _{n\to c}f(n)=L and is read as "the limit of f of n as n approaches c equals L". The fact that a function f(n) approaches the limit L as n approaches c is sometimes denoted by a right arrow (→), as in {\displaystyle f(n)\to L\ .} f(n)\to L\ .

    -The helical polypeptide molecules may fold in itself and assumes a complex but specific form. -it may be rod shaped or spherical or any other form. These specific geometrical shapes are known as tertiary structure of proteins. -It is 3D structure of proteins. -It is maintained by disulphite bond and H bond,ionic bond,hydrophobic interaction, hydrophilic interaction, vanderwall force Tertiary structure is affected by:- PH, temperature, chemical The tertiary structure is mainly observerd in globular proteins

    Yogita Ingle 7 years ago

    • Bonds between neighboring amino acids results in further folded structure
    • Tertiary structure depends upon the primary structure
    • Creates active sites of enzymatic proteins
    • Some of the tertiary structures are spherical forming Globular proteins; while some others are like long fibers forming Fibrous proteins

    Identifiers or User Define Words:-

    Identifiers will be used as class variables methods etc while naming the identifiers or user define words remember the following paths-

    1. Keywords cannot be used as identifiers.

    2. Identifier must not start with any numeric or it is always recommendable to starts some of the identifiers with small case.

    3. It must not contain any special symbol other than (_ or $).

    4.Identifier must not contain any blank space in between.

    5.Identifiers may contain numeric but it should not be in starting.

    For e.g. –

    int ab; //ok

    int a_b; //ok

    int a b; // not ok

    class Hello{

    int a;

    int ab;

    The general valence shell electronic configuration of p-block elements is ns2 np1-6 where n=2-6.
    The highest oxidation state of the elements of p-block is numerically equal to group number minus 10 or number of valence electrons. This highest oxidation state exhibited by all the elements in a particular group is known as group oxidation state. For example , For 13 group , Group number =13
    Highest oxidation state=13-10=+3
    Therefore, group 13 elements have +3 group oxidation state.

    As carbon and silicon are of same group, but carbon comes first and silicon second. As we know when we goes down a group , size of the elements increases , so they prefer to make sigma bond rather than pie bond. So carbon makes pie bond with oxygen and as we all know pie bonds are weak so co2 is a gas. But in case of SiO2 it makes sigma bond with oxygen and due to strong bond SiO2 is solid . For more clearance please the structure of SiO2 in ncert 2nd textbook , chapter p block.

    1Thank You

    Divya Tripathy 7 years ago

    It is all due to vander wall forces. The CO2 has less intermolecular forces. The sio2 has strong intermolecular forces or vander wall forces due to which it binds its molecules or atoms. So therefore sio2 is solid
