Correct answer: Spermatogonia-spermatocyte-spermatid-sperms- A. Proteins
- B. Mitochondria
- C. Centriole
- D. Nucleus
Explanation: The middle piece of a sperm cell contains mitochondria, which are the energy-producing organelles of the cell.
Correct answer: Mitochondria- A. Capacitation
- B. Release of lysin
- C. Influx of Na+
- D. Release of fertilizin
Explanation: The acrosome of a sperm contains enzymes, including lysin, which are involved in breaking down the protective layers surrounding the egg.
Correct answer: Release of lysin- A. Fertilization
- B. Reproduction
- C. Regeneration
- D. Embryology
Explanation: Reproduction is the biological process of producing offspring, ensuring continuity of species.
Correct answer: Reproduction- A. Binary fission
- B. Conjugation
- C. Budding
- D. Fragmentation
Explanation: Yeast reproduces asexually by budding, forming a small outgrowth that detaches into a new cell.
Correct answer: Budding- A. Binary fission
- B. Budding
- C. Sporulation
- D. Fragmentation
Explanation: Hydra reproduces asexually by budding from its body wall.
Correct answer: Budding- A. Conjugation
- B. Binary fission
- C. Sporulation
- D. Budding
Explanation: Bacteria divide by simple binary fission, producing identical daughter cells.
Correct answer: Binary fission- A. Menstruation
- B. Proliferation
- C. Post ovulation
- D. Ovulation
Explanation: Menstruation is the periodic shedding of the uterine lining when implantation does not occur.
Correct answer: Menstruation- A. Oestrogen
- B. Progesterone
- C. Oxytocin
- D. Testosterone
Explanation: Progesterone is secreted by the corpus luteum to maintain the endometrium for possible implantation.
Correct answer: Progesterone- A. Ovulation
- B. Abortion
- C. Menstruation
- D. Secretion
Explanation: Menstruation is the natural discharge of blood and endometrial tissue from the uterus.
Correct answer: Menstruation- A. 250 days
- B. 260 days
- C. 270 days
- D. 280 days
Explanation: Human gestation lasts about 280 days, roughly nine months.
Correct answer: 280 days- A. Oogenesis
- B. Spermatogenesis
- C. Fertilization
- D. Development of embryo
Explanation: Spermatogenesis is the process of sperm formation occurring in the seminiferous tubules of testes.
Correct answer: Spermatogenesis- A. Two
- B. Four
- C. Six
- D. Eight
Explanation: One primary spermatocyte divides into two secondary spermatocytes, each producing two sperms.
Correct answer: Eight- A. One
- B. Two
- C. Three
- D. Four
Explanation: One primary oocyte produces one ovum and three polar bodies during meiosis; only the ovum is functional.
Correct answer: One- A. Spermatogonium
- B. Primary spermatocyte
- C. Primary oocyte
- D. Spermatid
Explanation: Spermatids are haploid cells formed after meiosis II of secondary spermatocytes.
Correct answer: Spermatid- A. 1
- B. 2
- C. 3
- D. 4
Explanation: Each secondary spermatocyte produces 2 sperms; two secondary spermatocytes therefore produce 4 sperms.
Correct answer: 4- A. Secondary spermatocytes
- B. Spematogonia
- C. Spermatids
- D. Spermatozoa
Explanation: Spermatogonia in the seminiferous tubules divide and differentiate to form primary spermatocytes.
Correct answer: Spematogonia- A. Epididymis
- B. Seminiferous tubules
- C. Vas deferens
- D. Prostate gland
Explanation: Sperm are formed inside seminiferous tubules of testes.
Correct answer: Seminiferous tubules- A. DNA replication
- B. Entry into ovum
- C. Locomotion
- D. Providing energy
Explanation: Acrosome contains enzymes that digest egg membranes.
Correct answer: Entry into ovum- A. Follicle
- B. Corpus luteum
- C. Pituitary gland
- D. Placenta only
Explanation: Corpus luteum secretes progesterone to maintain pregnancy.
Correct answer: Corpus luteum
