Plant Tissue Culture
It refers to culture or growing the plant tissues. Plant tissue culture is developed as a separate branch of science - ever since the potentiality of each cell or tissue of plant to grow into a separate organism has been recognised. Tissue culture technique has opened up new opportunities in ..
Summary Simultaneous Equations
Finding the solution by the method of substitution. Finding the solution by the method of substitution. (i) Coefficients of one of the variables (say x) in the two equations are made equal, by multiplying them with suitable factors. (ii) By addition or subtraction, this var..
Molecular Orbital Theory
Molecular orbital theory was proposed by F. Hund and R.S. Mulliken in 1932. The basic idea of molecular orbital theory is that atomic orbitals of individual atoms combine to form molecular orbitals. The electrons in molecules are present in the molecular orbitals, which are associated with several ..
Simultaneous Equations
Consider a linear equations in two variables , say, 3x - 2y = 5. It has an infinite number of solutions, some of these are x = 0, Consider a linear equations in two variables , say, 3x - 2y = 5. It has an infinite number of solutions, some of these are x = 0, y = 0. Similarly, if we take another eq..

Point of intersection of two lines
Then (x 1 , y 1 ) lies on both (i) and (ii). Solving for x 1 and y 1 by the method of cross multiplication, we obtain ..
Plant Tissue Culture
It refers to culture or growing the plant tissues. Plant tissue culture is developed as a separate branch of science - ever since the potentiality of each cell or tissue of plant to grow into a separate organism has been recognised. Tissue culture technique has opened up new opportunities in evolvi..
Case I:
Pre-multiply by A - 1 , \ A - 1 (AX) = A - 1 B \ (A - 1 A) X = A - 1 B \ I X = A - 1 B or X = A - 1 B This is the matrix method to solve the equations. However, ..
Judicious use of Energy
. By thinking whether or not an electric light is needed or by switching it off when not required the fuel resources of the world can be conserved. Modern homes are built to conserve fuel by using building materials and methods that insulate the house. In the colder parts of the world ins..
Consistency of a system of linear equation
If a system of linear equations has at least one solution, then the system is called consistent, otherwise it is called inconsistent. Solve the system of linear equations (1) by using method of elimination as studied earlier Multiplying the first equation by a 2 and the second..
