  • Question 1
    1 / -0
    Which one of the following events is correctly matched with the time period in a normal menstrual cycle?
    Solution
    Menstrual cycle is divided into three phases: follicular, ovulatory and luteal.
    1. During 1-4 days of follicular phase, there is low secretion of Follicle stimulating hormone (FSH) and Luteinizing hormone (LH). Primary follicles grow and outer two thirds of endometrium shed off.
    2. During 5-13 day of follicular phase, FSH secretion increases. Follicles grow and Graafian follicles develops. Mitotic division increases thickness of endometrium.
    3. During ovulatory phase which occurs during 14 days, there is LH surge and increased secretion of FSH. Graafian follicle ruptures and secondary oocyte is extruded into uterine tube. The ovulation occurs on 14th day. There is no change in Endometrium.
    4. During luteal phase which occurs during 15-28 days, LH and FSH decrease. There is development of Corpus luteum and glandular development in endometrium due to progesterone stimulation.
    Hence, the correct option is option B stating the regeneration of Endometrium in 5-10 days i.e. during follicular phase.
    So, the correct answer is 'Endometrium regenerates- 5 - 10 days'.
  • Question 2
    1 / -0
    How macula lutea and corpus luteum are related?
    Solution
    Both corpus luteum and macula lutea are characterised by yellow colour pigment, called lulein. It occur as a yellow area of retina as yellow spot. Thus, the correct answer is option C.
  • Question 3
    1 / -0
    In humans at the end of first meiotic division, the male germ cells differentiate into 
    Solution
    Correct option: B
    Explanation:

    Each spermatogonium is produced from the primordial germ cell then actively grows to a larger primary spermatocyte.
    Each primary spermatocyte divides meiotically and produces haploid secondary spermatocytes.
    Thus, the correct answer is option B.

  • Question 4
    1 / -0
    Study of abnormal embryonic growth comes under
    Solution
    Teratology is the study of abnormal embryonic growth, abnormal formations and congential abnormalities.
    Ontogeny is the study of developmental history of an organism which starts from fertilization to the maturation of organism.
    Morphogenesis is the origin and development of morphological characteristics. The study of morphological character is known as morphogenesis.
    Parthenogenesis is a mode of asexual reproduction in which growth and development of embryos occur without fertilization. In animals, parthenogenesis means development of an embryo from an unfertilized egg cell.
    So, the correct answer is option A.
  • Question 5
    1 / -0
    Cessation of menstrual cycle in the human female is known as 
    Solution
    Ovulation is the process of releasing the matured egg or ovum.
    Puberty is the process of physical changes whereby the child's body matures into an adult body capable of sexual reproduction.
    The cessation of the woman's menstrual cycle and hence the end of reproductive ability is called as menopause. Menopause occurs due to the natural cessation of the estradiol and progesterone production by the ovaries over a period of years. This is the part of the normal aging process.
    The process of becoming mature is maturation.
    Thus, the correct answer is (C), 'Menopause'.
  • Question 6
    1 / -0
    Seminal plasma in human males is rich in
    Solution
    Seminal plasma in human males is rich in fructose and calcium because it provides nourishment and protection to spam and also provides a medium for transport.
    So, the correct answer is 'Fructose and calcium'.
  • Question 7
    1 / -0
    The menstrual cycle in normal adult woman is of 
    Solution
    The menstrual cycle is the rhythmic natural changes in a female body for sexual reproduction. It is governed by internal biological cycles. The menstrual cycle consists of three phases based on the events in the ovary, which lasts for 28 days.
    Thus, the correct answer is D.
  • Question 8
    1 / -0
    Ovulation in mammals is caused by
    Solution
    LH and FSH are hormones secreted by the anterior pituitary. The release of the oocyte from the ovary is called ovulation. The LH bring about ovulation while FSH helps in the development of ovary.
    So, the correct answer is option B.
  • Question 9
    1 / -0
    Seminiferous tubules are found in 
    Solution
    The inside of the testes is divided into small compartments called lobules. Each lobule contains a section of seminiferous tubule lined with epithelial cells.
    Therefore, the correct answer is option A.
  • Question 10
    1 / -0
    Fixing up of the blastocyst in the wall of the uterus is known as
    Solution
    The reproductive events in humans include formation of gametes (gametogenesis), i.e., sperms in males and ovum in females, transfer of sperms into the female genital tract (insemination) and fusion of male and female gametes (fertilisation) leading to formation of zygote. 
    This is followed by formation and development of blastocyst and its attachment to the uterine wall (implantation), embryonic development (gestation) and delivery of the baby (parturition).
