    When the concentration of water is higher than that of cell the cell swells up this is called hypertonic solution and when the concentration of water and cell are same and cell does not swells up then it is called isotonic solution

    Suspension it is a heterogeneous solution having a unstable particles its particles are greater than the particles of true solution it does not show tyndall effect. Colloidal solution it is a a heterogeneous solution appears to be true solution its particles are are having a size between suspension and true solution it shows tyndall effect and the particles settle down it is also known as colloidal SOL

    Distribution of electrons or arrangement of electrons in an atom(in shell or orbit) of an element is called electronic configuration. It is denoted by the 2(n)square. For example, k shell is the 1st shell so here n=1. Therefore, 2(1)square=2 It means that k shell or first shell has the capacity to hold 2 electrons. Similarly by this formula we can find the distribution of electrons in each shell. L shell or second can hold 8 electrons. M shell or third shell can hold 18 electrons. N shell or fourth shell can hold 32 electrons.

    The process of minimizing an impact force can be approached from the definition of the impulse of force: If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the impact force by the same factor. Non-impulsive Force:  A constant force acting on a body is an example of non-impulsive force Why does cricketer move his hand backwards while catching a fast moving cricket ball ?? Because, While catching a fast moving cricket ball,afielder in the ground gradually pulls his hand backward with the moving ball,In doing so, the fielder increases the time during which the high velocity of the moving ball decrease to zero. Thus, the acceleration of the ball is decreased and therefore the impact of catching the fast moving ball is also reduced. If the ball stopped suddenly then its high velocity is decreased to zero in a very short interval of time. Thus, the rate of change of momentum ofthe ball will be large. Therefore, a large force would have to be applied for holding the catch that may hurt the palm of the fielder.

    The nucleus is the membrane bound important structure of the cell. Nucleus regulates all the cellular activities by controlling the enzymes required for cellular processes. It contains genetic information in the form of genes located in the chromosomes. It brings about growth of the cell by directing the synthesis of structural proteins. It also controls all the metabolic activities of the cell.
