Explanation: Pericarp refers to the part of a fruit formed from the wall of the ripened ovary.
Correct answer: Option B- A. Binary fission
- B. Multiple fission
- C. Budding
- D. Regeneration
Explanation: Hydra reproduce asexually by budding. The buds form from the body wall, grow into miniature adults and break away when mature.
Correct answer: Budding- A. Leydig cells
- B. Hensen's node cells
- C. Sertoli cells
- D. Interstitial cells
Explanation: In the male, inhibin B is produced in the testis, principally by the Sertoli cells.
Correct answer: Sertoli cells- A. Follicle-stimulating, and luteinizing, estrogen
- B. Estrogen and follicle-stimulating, luteinizing
- C. Luteinizing arid estrogen, follicle-stimulating
- D. Follicle-stimulating and estrogen, luteinizing
Explanation: The pituitary gland releases the follicle-stimulating hormone and luteinizing hormone while ovaries produce estrogen and progesterone.

Explanation: The female gametes are most commonly referred to as eggs or ova (singular: ovum).
Correct answer: All of these- A. Ovulation
- B. Beginning of menses
- C. Corpus luteum formation
- D. Maturation of ovarian follicle
Explanation: During the menstrual cycle, the level of progesterone in the body increases after ovulation and reaches its peak about one week later.
Correct answer: Beginning of menses- A. Nerve cells
- B. Fat cells
- C. Muscle cells
- D. Interstitial cells
Explanation: The cells that secrete testosterone are the Leydig cells, also known as interstitial cells.

- D. Vas deferens
Explanation: After traveling through the epididymis, sperm cells enter the vas deferens.
Correct answer: Vas deferens- A. Vas deferens
- B. Ureter
- C. Urinary bladder
- D. Urethra
Explanation: Explanation for this question will be added soon.
Correct answer: Urethra- A. Progesterone

- C. Implantation
- D. Menstruation
Explanation: Implantation refers to the zygote geing attached to the wall of the womb so that further stages in the growth of zygote can occur, and…
Correct answer: Implantation- A. The lining of the womb wall stays built up.
- B. The lining of the womb wall builds up again.
- C. Another egg is immediately released.
- D. The lining of the womb wall breaks down.
