D Growth rate = CDR minus CBR plus migration rate
Show answer & explanation
Answer: C. Growth rate = CBR minus CDR (per 1000 population)
Why: The natural population growth rate is calculated as Crude Birth Rate (CBR) minus Crude Death Rate (CDR) per 1000 population. Positive values indicate population increase.
Q47.
Why is the MTP Act considered to have both benefits and potential for misuse in the Indian context?
A It reduces maternal mortality from unsafe procedures but correlates with rising STI transmission rates
B It prevents unsafe abortions but is misused for sex-selective abortions leading to female feticide
C It improves access to family planning but is linked to increased rates of male infertility
D It slows population growth rates but introduces surgical complications during delivery
Show answer & explanation
Answer: B. It prevents unsafe abortions but is misused for sex-selective abortions leading to female feticide
Why: The MTP Act prevents unsafe back-alley abortions and reduces maternal mortality. However, it has been misused for sex-selective abortions to terminate female fetuses, leading to skewed sex ratios, which is why the PCPNDT Act was enacted.
Q48.
In ART, IUT (Intrauterine Transfer) is used when the embryo from IVF is transferred into the uterus, but ZIFT is used when it is transferred into which structure?
A Peritoneal cavity
B Ovarian follicle
C Fallopian tube
D Cervical canal
Show answer & explanation
Answer: C. Fallopian tube
Why: In ZIFT (Zygote Intrafallopian Transfer), the zygote or early embryo obtained from IVF is transferred into the fallopian tube, allowing it to travel naturally to the uterus for implantation.

C Blood transfusion > needle sharing > mother to child > sexual intercourse
D Mother to child > blood transfusion > sexual intercourse > needle sharing
Show answer & explanation
Answer: C. Blood transfusion > needle sharing > mother to child > sexual intercourse
Why: HIV transmission probability per exposure: blood transfusion (90-95%) is highest, followed by needle sharing (0.67%), then mother-to-child transmission (15-45%), and sexual intercourse (0.1-1% depending on type).
Q54.
Why does copper in CuT IUDs act as a spermicide, from a biochemical perspective?
A Copper ions diffuse into vaginal fluid, lowering pH sharply enough to denature sperm membranes
B Copper ions interfere with sperm enzymes (acrosin, adenyl cyclase), impairing motility and capacitation
C Copper ions precipitate at the cervical os, forming a physical plug against sperm entry
D Copper ions provoke a local immune response that generates antibodies against sperm surface antigens
Show answer & explanation
Answer: B. Copper ions interfere with sperm enzymes (acrosin, adenyl cyclase), impairing motility and capacitation
Why: Copper ions (Cu2+) interfere with key sperm enzymes including acrosin and adenyl cyclase, impair calcium channel function needed for motility, reduce ATP production, and inhibit capacitation, rendering sperm unable to fertilise.
Q55.
India total fertility rate (TFR) dropped below the replacement level of 2.1 for the first time according to NFHS-5 (2019-21). What does a TFR below replacement level indicate about future population trends?
A An immediate and sharp decline in total population size within the same year
B Population will continue growing for decades due to population momentum before stabilising
C An acceleration of population growth driven by the existing large reproductive-age cohort
D A death rate that immediately surpasses the birth rate across all age groups
Show answer & explanation
Answer: B. Population will continue growing for decades due to population momentum before stabilising
Why: Even when TFR drops below replacement level, population continues to grow for decades due to population momentum - the large proportion of young people who will still have children. India population is projected to peak around 2064.
Q56.
Spermicidal creams and jellies used with barrier methods work by which mechanism?
A Forming a physical barrier directly over the narrow cervical opening
B Chemically immobilising or killing sperm on contact
C Altering cervical mucus consistency mainly to trap and slow down sperm
D Lowering testosterone levels in males gradually over an extended period
Show answer & explanation
Answer: B. Chemically immobilising or killing sperm on contact
Why: Spermicides contain chemicals like nonoxynol-9 that chemically immobilise or kill sperm by disrupting their cell membranes. They are most effective when used in combination with barrier methods like diaphragms.
