After fertilization, cell division occurs through a process of:

  • A. Binary fission
  • B. Meiosis
  • C. Budding
  • D. Mitosis
Correct Answer: D

Rationale: After fertilization, the zygote undergoes cell division through the process of mitosis. Mitosis is the type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. Choice A, binary fission, is a form of asexual reproduction in prokaryotes, not the process that occurs after fertilization in multicellular organisms. Choice B, meiosis, is a type of cell division that leads to the formation of gametes with half the number of chromosomes, not the process that occurs after fertilization. Choice C, budding, is a form of asexual reproduction seen in some organisms like yeast, but it is not the process of cell division after fertilization.

Which of the following is a contraceptive?

  • A. Copper T
  • B. Condom
  • C. Diaphragm
  • D. All of these
Correct Answer: D

Rationale: The correct answer is D, All of these. Copper T, Condom, and Diaphragm are all examples of contraceptives used to prevent pregnancy. Copper T is an intrauterine device (IUD) that is placed inside the uterus to prevent pregnancy. Condoms are barrier contraceptives worn over the penis or inserted into the vagina to prevent sperm from reaching the egg. Diaphragms are also barrier contraceptives that cover the cervix to prevent sperm from entering the uterus. Therefore, all options listed (Copper T, Condom, Diaphragm) are indeed contraceptives, making 'All of these' the correct choice.

At 6-8 weeks of pregnancy, the breast changes include:

  • A. Colostrum can be expressed.
  • B. Breasts become tender.
  • C. Montgomery's tubercles are prominent.
  • D. Nipples become prominent and mobile.
Correct Answer: C

Rationale: At 6-8 weeks of pregnancy, one of the changes in the breast includes the prominence of Montgomery's tubercles. These sebaceous glands around the nipple become more noticeable at this stage. Colostrum production usually occurs later in pregnancy, typically closer to the third trimester. While breast tenderness is a common symptom of early pregnancy, it is not specific to the 6-8 week timeframe. Nipples becoming more prominent and mobile may happen later in pregnancy as the body prepares for breastfeeding, but it is not a typical change seen specifically at 6-8 weeks.

What is the role of relaxin hormone?

  • A. Relaxation of the symphysis pubis.
  • B. Stimulation of milk production.
  • C. Stimulating the development of the nipple and duct system in the breast.
  • D. None of the above.
Correct Answer: A

Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.
