- A. Penis
- B. Urethra
- C. Sperm duct
- D. Scrotum
Explanation: The structure that surrounds the testicles is the scrotum. The scrotum is a pouch of skin and muscle that houses and protects the testes.
Correct answer: Scrotum- A. Parthenocarpy
- B. Apomixis
- C. Parthenogenesis
- D. All of these
Explanation: Parthenocarpy leads to the development of fruits without seeds, that means they can not further reproduce.
Correct answer: Parthenogenesis- A. Internal fertilization with external development in eggs
- B. Internal fertilization and internal development followed by hatching of egg
- C. External fertilization with external development
- D. Internal fertilization with internal development inside female body
Explanation: Viviparous animals are those that have sexual intercourse due to which the sperm and egg cell fuse and form an embryo in the female body.
Correct answer: Internal fertilization with internal development inside female body- A. Parthenocarpy
- B. Parthenogenesis
- C. Vernalization
- D. All of these options are correct
Explanation: In flowering plants, one form of parthenogenesis is called apomixis. Apomixis is a mechanism by which plants can reproduce clonally…
Correct answer: Parthenogenesis605. A human cell from the ovary has 22 chromosomes and an X chromosome. It is which of the following?
- A. Egg
- B. Sperm
- C. Somatic cell
- D. Gamete
Explanation: In humans, each cell nucleus contains 23 pairs of chromosomes, a total of 46 chromosomes. The first 22 pairs are called autosomes.
Correct answer: Egg- A. Ejaculatory duct
- B. Seminal vesicle
- C. Seminiferous tubules
- D. Epididymis
Explanation: The epididymis is a coiled tube located on the testes where spermatozoa are stored and undergo maturation.
Correct answer: Epididymis- A. One of both testes are not developed
- B. One or both testes fail to descend into the scrotum
- C. One or both testes are not formed
- D. None of these
Explanation: Cryptorchidism is a condition that affects males and presents itself in the early stages of life however is resolves on its own during the…
Correct answer: One or both testes fail to descend into the scrotum- A. Seed dormancy
- B. Fruit ripening
- C. Germination
- D. All of these
Explanation: . Option C is correct since germination is defined as the sprouting of a seed, spore, or other reproductive body, usually after a period…
Correct answer: Germination- A. 20 days
- B. 28 days
- C. 10 days
- D. 40 days
Explanation: Option B is correct since the average length of the menstrual cycle in an adult female is 28 days.Option A is incorrect since the 20-day…
Correct answer: 28 days- A. Andropause
- B. Gametopause
- C. Menopause
- D. All of these
Explanation: Menopause is a natural biological process that marks the end of a woman's menstrual cycle.
Correct answer: Menopause- A. Sporulation
- B. Apomixis
- C. Fission
- D. All of these
Explanation: Apomixes, Sporulation and Fission are methods that are of asexually reproducing.
Correct answer: All of these- A. Epididymis
- B. Scrotal sacs
- C. Seminal vesicle
- D. Prostate gland
Explanation: Sperm production in the testes takes place in coiled structures called seminiferous tubules.
Correct answer: Epididymis- A. Anaphase I
- B. Prophase I
- C. Metaphase I
- D. Metaphase II
Explanation: After ovulation, the oocyte is arrested in metaphase of meiosis II until fertilization.
Correct answer: Metaphase II- A. Somatic cell
- B. Egg cell
- C. Sperm cell
- D. Zygote
Explanation: Option B is correct since in animals and especially among vertebrates, a nucleus from somatic cells is removed and introduced into an egg…
Correct answer: Egg cell- A. Ovaries
- B. Vagina
- C. Fallopian tubes
- D. Uterus
Explanation: Option A is correct since thousands of eggs are found in the ovaries of the female reproductive system.The ovaries are a pair of small…
Correct answer: Ovaries- A. Gametes
- B. Gonads
- C. Glands
- D. Follicles
Explanation: The primary reproductive organs are gonads, which produce reproductive cells (gametes).
Correct answer: Gonads- A. 28 days
- B. 250 days
- C. 280 days
- D. 300 days
Explanation: The gestation period refers to the length of time from conception to birth.
Correct answer: 280 days- A. Meiosis
- B. Fertilization
- C. Ovulation
- D. Oogenesis
Explanation: Option D is correct because oogenesis is the process in which the formation of egg cells begins in the developing female fetus.
Correct answer: Oogenesis- A. Ovary
- B. Vagina
- C. Uterine tube
- D. Prostate gland
Explanation: The prostate is located in male reproductive system just below the bladder and in front of the rectum.
Correct answer: Prostate gland- A. Lower than body temperature
- B. Body temperature
- C. Higher than body temperature
- D. All of these
Explanation: Sperm development (spermatogenesis) occurs at a temperature lower than body temperature.
