Reproductive Health MCQ Chapter 4 Question 3.
Intensely lactating mothers do not generally conceive due to the
(A) suppression of gonadotropins.
(B) hyper-secretion of gonadotrophins.
(C) suppression of gametic transport.
(D) suppression of fertilisation.
Answer:
(A) suppression of gonadotropins.
Explanation :
Breast-feeding is one of the tern porary and natural contraceptive methods which reduce the secretion of oestrogen hormone and thereby suppress ovulation (release of egg) and cause amenorrhoea. The contraceptive effect of the lactational amenorrhoea method is a result of increased levels of prolactin. In this condition, production and secretion of gonadotrophin-releasing hormones are inhibited and result in low secretion of oestrogen. As ovulation cannot occur without a surge in oestrogen levels, and if a woman does not ovulate, pregnancy is prevented.
Chapter 4 Biology Class 12 MCQ Question 4.
Condoms are one of the most popular contraceptives because of the following reasons.
(A) These are effective barriers for insemination.
(B) They do not interfere with coital act.
(C) These help in reducing the risk of STDs.
(D) All of the above
Answer:
(D) All of the above
Explanation:
Condoms can both prevent pregnancy by stopping sperm from meeting an egg, They also protect against sexually-transmitted infections (STIs). Condoms act as a barrier method of contraception. They are made up of very thin latex (rubber) and are designed to prevent pregnancy by stopping sperm from meeting an egg. They do not interfere with coital act.
MCQ Of Reproductive Health Class 12 Chapter 4 Question 5.
The correct surgical procedure as a contraceptive method is
(A) ovariectomy.
(B) hysterectomy.
(C) vasectomy.
(D) castration.
Answer:
(C) vasectomy.
Explanation :
Vasectomy is the correct surgical procedure as a contraceptive method in male. During this procedure, vas deferens is cut down to prevent sperm from entering into the urethra and thereby preventing fertilisation. In female, this procedure is called tubectomy in which Fallopian tubes are held and blocked or severed and sealed, either of which prevents eggs from reaching the uterus for implantation. Removal of ovary; uterus and testes are called as ovariectomy, hysterectomy and cas tration respectively Vasectomy is the correct surgical procedure as a contraceptive method in male. During this procedure, vas deferens is cut down to prevent sperm from entering into the urethra and thereby preventing fertilisation. In female, this procedure is called tubec tomy in which Fallopian tubes are held and blocked or severed and sealed, either of which prevents eggs from reaching the uterus for implantation. Removal of ovary uterus and testes are called as ovariectomy, hysterectomy and castration respectively.
MCQ Of Chapter 4 Biology Class 12 Question 6.
Increased IMR and decreased MMR in a population will
(A) cause rapid increase in growth rate.
(B) result in decline in growth rate.
(C) not cause significant change in growth rate.
(D) result in an explosive population/exp.
Answer:
(B) result in decline in growth rate.
Explanation :
Both IMR (infant mortality rate) and MMR (maternal mortality rate) are responsible for affecting the growth rate inversely It means decline in IMR, as well as MMR, will result in high population growth and vice versa. Hence, if there is an increased IMR and decreased MMR in a population mothers are there to give births to infants whereas the survival rate of infants becomes low. Therefore, in a particular population, increased IMR and decreased MMR will hinder their growth rate.
