A woman has certain queries as listed below, before starting with contraceptive pills. Answer them.
What schedule should be followed for taking these pills?

Read the following passage and answer the questions. There are certain substances which behave as normal strong electrolytes at low concentration but at higher concentration they behave as colloidal solutions due to the formation of aggregated particles. Such colloids are called associated colloids and the aggregated particles are called micelles. Soaps and detergents are the examples of associated colloids. The formation of micelles takes place above certain concentration called critical micellisation concentration (CMC) and a characteristic temperature called Kraft temperature. In case of colloids, what does CMC stand for ?

(a) medical termination of pregnancy (MTP) during first trimester is generally save, (b) generally chances of conception are Nil until mother breast-feeds the infant up to 2 years. (c) intrauterine devices like copper-T are effective contraceptives. (d) Contraceptive pills may be taken up to 1 week after coitus to prevent conception. which two of the above statements are correct?

Read the given passage and answers following questions : Zeolites are alumino-silicates that are micro-porous in nature. Zeolites have a honeycomb like structure, which makes them shape-selective catalysts. They have an extended 3D-nelwork of silicates in which some silicon atoms are replaced by aluminium atoms, giving them an Al-O-Si framework. The reactions taking place in zeolites are very sensitive to the pores and cavity size of the zeolites. Zeolites are commonly used in the petrochemical industry. A catalytic reaction which depends upon the pore structure of the catalyst and on the size of the reactant and the product molecules is called shape-selective catalysis. For example, catalysis by zeolites is a shape selective catalysis. The pore size present in the zeolites ranges from 260-740 pm. Thus, molecules having a pore size more than this cannot enter the zeolite and undergo the reaction. What is the pore size of Zeolites ?
