- D. None of the above
Explanation: Vegetative propagation in Bryophyllum mainly occurs through its leaves.
Correct answer: Leaf- A. Frog
- B. Fish
- C. Earthworm
- D. Cockroach
Explanation: Earthworms are indeed hermaphrodites. They possess both male and female reproductive organs, allowing them to produce both sperm and eggs.
Correct answer: Earthworm- A. Yeast
- B. Paramoecium
- C. Plasmodium
- D. Rhizopus
Explanation: Plasmodium, a protoctista and the causative agent of malaria, undergoes multiple fission as part of its life cycle.
Correct answer: Plasmodium- A. Ovarian follicle
- B. Graffian follicle
- C. Corpus luteum
- D. Corpus albicans
Explanation: After ovulation, the Graafian follicle transforms into the corpus luteum.
Correct answer: Corpus luteum- A. FSH
- B. Luteinizing hormone
- C. Oestrogen
- D. Progesterone
Explanation: LH is secreted by the anterior pituitary gland. LH surge triggers ovulation.
Correct answer: Luteinizing hormone- A. Same as
- B. Lower than
- C. Higher than
- D. Immaterial to
Explanation: Sperms are produced in the testes, which are located outside the body within the scrotum.
Correct answer: Lower than- A. Acrosome
- B. Nucleus
- C. Mid-piece
- D. Tail
Explanation: The acrosome is a structure at the tip of the sperm cell that contains enzymes, including lytic enzymes.
Correct answer: Acrosome- A. 2 days
- B. 1-3 days
- C. 1-3 weeks
- D. 7 days
Explanation: The range encompasses the typical lifespan of sperm, which is generally considered to be around 1 to 3 days.
Correct answer: 1-3 days- A. Vas deferens
- B. Vas efferens
- C. Epididymis
- D. Bladder
Explanation: The epididymis is a coiled tube located on the back of each testicle where sperm mature and are stored before ejaculation.
Correct answer: Epididymis- A. Hormones
- B. Glands
- C. Gonads
- D. Prostaglandins
Explanation: The endocrine system is primarily made up of glands because glands are the specialized organs responsible for producing and secreting…
Correct answer: Glands- A. Affects only the reproductive system
- B. Releases hormones into the bloodstream
- C. Competes with the nervous system
- D. Is made up primarily of glands with ducts
Explanation: One of the primary functions of the endocrine system is to release hormones directly into the bloodstream.
Correct answer: Releases hormones into the bloodstream- A. Sweat gland
- B. Tear gland
- C. Pituitary gland
- D. All of the above
Explanation: The pituitary gland, often referred to as the "master gland," is a crucial component of the endocrine system.
Correct answer: Pituitary gland- A. Hormones
