When RNA is hydrolsed, there is no relationship among the quantities of different bases obtained. What does this fact suggest about the structure of RNA?

The following graph shows the species area relationship. Answer the following questions as directed. Write the situations as discovered by the ecologists when the value of 'Z' (slope of the line) lies between 0.1 and 0.2 What does 'Z' stand for?

The following graph shows the species area relationship. Answer the following questions as directed. Write the situations as discovered by the ecologists when the value of 'Z' (slope of the line) lies between 0.6 and 1.2 What does 'Z' stand for?

A complex of the type [M(A A)_2X_2]^(n+) is known to be optically active. What does this indicate about the structure of the complex? Give an example of such complex.

Let X represent the difference between the number of heads and the number of tails obtained when a coin is tossed 6 times. What are possible values of X?

In nature, the failure of structural members usually result from large torque because of twisting or bending rather than due to tensile or compressive strains. This process of structural breakdown is called buckling and in cases of tall cylindrical structureslike trees, the torque is caused by its own weight bending the structure. Thus the vertical through the centre of gravity does not fall within the base. The elastic torque caused because of this bending about the central axis of the tree is given by (Ypir^4)/(4R) . Y is the Young's modulus, r is the radius of the trunk and R is the radius of curvature of the bent surface along the height of the tree containing the centre of gravity (the neuttral surface). EStimate the critical height of a tree for a given radius of the trunk.
