The bank has 1,808 active questions on this chapter. Your first 500 practice attempts are free, and every attempt includes a worked explanation.

  1. Question 1
    Placenta is established between:
    • Uterine and foetal tissues (correct answer)
    • Uterine and cervix
    • Cervix and vagina
    • Ovary and oviduct
    Correct answer: A
    The placenta, vital for fetal development, forms from a fusion of maternal uterine tissues and fetal placental tissues.
  2. Question 2
    Which of the following cells is haploid?
    • Oogonium
    • Primary oocyte
    • Follicle cell
    • Secondary oocyte (correct answer)
    Correct answer: D
    Distinguishes between haploid and diploid cells in oogenesis, focusing on the ploidy of the secondary oocyte after meiosis I.
  3. Question 3
    The birth of the first child will be a fatal situation in which of the following conditions?
    • Male Rh+ & Female Rh- (correct answer)
    • Male Rh- & Female Rh+
    • Male Rh- & Female Rh-
    • None of the above
    Correct answer: A
    Rh incompatibility can lead to hemolytic disease of the newborn, posing a risk to subsequent pregnancies.
  4. Question 4
    All of the following organs produce hormones involved in the reproductive cycle except the:
    • Testes
    • Pituitary Gland
    • Pancreas (correct answer)
    • Ovary
    • Uterus
    Correct answer: C
    Identify endocrine glands involved in the reproductive cycle, distinguishing them from those with other primary functions like metabolism.
  5. Question 5
    Reproduction is very important to the survival of
    • Species (correct answer)
    • Individual
    • Community
    • Both A and B
    Correct answer: A
    Reproduction is crucial for the continuation of a species, ensuring genetic diversity and long-term survival, not just the individual organism.
  6. Question 6
    How many ova and sperms would be produced from 100 secondary oocytes and 100 secondary spermatocytes during gametogenesis in humans?
    • 100 ova, 200 sperms (correct answer)
    • 100 ova, 100 sperms
    • 50 ova, 100 sperms
    • 200 ova, 200 sperms
    Correct answer: A
    Distinguishes oogenesis & spermatogenesis outcomes from secondary gametocytes, highlighting unequal vs. equal cytokinesis and one vs. four gamete production.
  7. Question 7
    The lining or inner layer of the uterus is called the _______.
    • Myometrium
    • Perimetrium
    • Endometrium (correct answer)
    • Both A and C
    Correct answer: C
    The uterus wall has three layers: the outer perimetrium, the muscular myometrium, and the inner, hormone-responsive endometrium where implantation occurs.
  8. Question 8
    Asexual reproduction does not introduce
    • Variation (correct answer)
    • Similarity between parents & offspring
    • Same chromosomal number in offspring
    • All of the choices are incorrect
    Correct answer: A
    Asexual reproduction bypasses genetic recombination, thus preventing the introduction of new variations into the offspring.
