Assertion : Human ancestors never used their tails and so the tail expressing gene has diappeared in them. Reason : Lamarck's theory of evolution is popularly called theory of continuity of germ plasm.

Assertion :-Charles Robert Darwin strongly challanged the ideas of special creation theory. Reason :- Darwin was influenced by idea of use and disuse of lamarck.

The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate, thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles "liter"^(-1) sec^(-1) . For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec^(-1) and atm. sec^(-1) The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances, thus, if the rate is found experimentally to be proportional to the alpha^(th) power of the concentration of one of the reactants A, to the beta^(th) power of the concentration of a second reactant B, and so forth, via., rate kC_(A)^(alpha) C_(B)^(beta)" " (1) the over-all order of the reaction is simply n = alpha +beta + ---------(2) Such a reaction is said to be of the alpha^(th) order with respect to the substance A, the beta^(th) order with respect to B and so on... (Laidler, K. J., & Glasstone, S. (1948). Rate, order and molecularity in chemical kinetics. Journal of Chemical Education, 25(7), 383.) In the following questions, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices on the basis of the above passage. Assertion: Reactions can occur at different speeds. Reason: Rate of reaction is also called speed of reaction.

One of the most important things to notice about the power of art is the way in which great works continue to exert their influence through the ages. Scientific discoveries which are of major importance at the time when they are made are superseded. Thus, Newton's theory of gravitation has been superseded by Einstein's theory of relativity. Hence the work of great scientists has value in stages on the way to a goal which supersedes them. Broadly speaking, the achievements of generals, politicians, and statesmen have an importance only in their own time. Hence these people and their acts, great as they may have been are like milestones which mankind passes on its way to something else. But with works of art it is not so. The place which they occupy in the estimation of succeeding ages and the power which they exercise over men's spirits are as great as they were in the age which produced them, indeed, their power tends to increase with time, as they came to be better understood. The statement "Newton's theory of gravitation has been superseded by Einstein's theory of relativity" suggests that

How is a work of art different from the work of a scientist ?
