Each question of a comprehension has only one correct answer among the fourchoices (1), (2), (3) and (4).Comprehension # 1 (Q.91 & Q.92) :- The term birth control was first used by Mr. Margaret Sanger who

    started a movement is USA to popularise it in 1916 for highlighting the world wide need of birth control,

    she declared "the first right of every child is to be wanted, to be desired, to be planned with an intensityof love that gives it its title to being". Today there is a pressing need for limiting the family size ata personal level and for the control of the population at national level. there are following two maintypes of birth control measures the contraception and abortion. Contraception is the prevention of fertilisation without destroying fertility by natural, mechanical or chemical means. Use of condom,occlusive , diaphragm, intrauterine Contraceptive devices (IUCD) like copper-T, use of spermicidalagents, Oral contraceptives are some common method of birth control, Spermicidal chemicals are alsoused. Another method of birth control is abortion which is defined as expulsion of products of conception whether it be spontaneous or induced before 12 week of gestation. In India, the medicaltermination of pregnancy (MTP act was passed by the Parliament in 1971 and came into force on

    April 1, 1972. It liberalized the abortion law as a family welfare measure to ensure better health andavoid risks to the lives of women.91. Prevention of fertilisation with destroying fertility is known as :-

    (1) Abortion(2) MTP(3) Contraception(4) Abstinence

    92. What is spermicidal agent ?(1) A chemical that inactivates spermatids(2) A chemical that kills spermatozoa

    (3) A chemical that prevents the implantation of foetus(4) A chemical that inactivates the testes

    Comprehension # 2 (Q.93 & Q.94) :- The union of the cytoplasm and pronuclei of the male and femalegametes is known as the fertilization. The fertilization is the most commonly used method for theproduction of the diploid zygotes is the sexually reproducing organisms of Metazoa & metaphyta, if the fertilization occurs outside the body of the organism, it is known as external fertilization & if it occursinside the body of the organism then it is termed as internal fertilization.

    Comprehension # 3 (Q.95 to Q.97) :- Our body is a well organised system and is made up of the structuraland functional units called cell. Cells are made up of different chemicals as carbohydrates, Proteins, Fats,minerals and salts. The cell is also having the cell membrane through which it keeps the relation with theexternal environment. Cell groups having same origin structure and function called as tissue, which further

    organise into the organs. Most advanced animals have the organ system of organisation. All the body organswork in co-ordination with each other and this coordination is established between the body organs bynervous system and the endocrine system. If this coordination breaks body organs do not work properlyin animal which is followed by the appearance of disease. A healthy person is who is mentally physicallyand socially well adjusted. Various diseases in body are identified by physicians on the basis of theirsysmptoms however, some of these are diagnosed by laboratory testing also. Diseases many be categorizedin to two groups, the infectious and noninfectious diseases .infectious diseases are caused by the infectionsof micro organisms which are also known as the pathogens. Non-infectious diseases may be deficiencydiseases or due to metabolic disorders.
