Correct answer is: option d) Eye
Explanation: The cornea and retina are both vital components of the eye, responsible for focusing light and converting it into signals that the brain can interpret as vision. The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber, and provides most of the eye's optical power. The retina is a light-sensitive layer of tissue, lining the inner surface of the eye.
- Option a: Palm is a part of the hand and has no connection to vision or the cornea/retina.
- Option b: Ear is responsible for hearing and balance, and it doesn't contain the cornea or retina.
- Option c: Nose is responsible for smell and is not involved in vision.
In which body part can one find the Synovial fluid?
Akhilesh ? Apr 1 '25 at 20:40
correct answer is: option d (d)[Joints]
Explanation: Synovial fluid is a viscous, non-Newtonian fluid found in the cavities of synovial joints. Its primary function is to reduce friction between the articular cartilage of synovial joints during movement. It also provides nutrients to the cartilage.
- Option a: Muscles are composed of muscle fibers and are responsible for movement. They do not contain synovial fluid.
- Option b: The Liver is a major organ involved in detoxification, protein synthesis, and the production of biochemicals necessary for digestion. It does not contain synovial fluid.
- Option c: The Kidney is responsible for filtering waste products from the blood and regulating fluid balance. It does not contain synovial fluid.
- Option d: Joints, specifically synovial joints, are where synovial fluid is located. The fluid lubricates the joint and reduces friction during movement.
Which disease is caused due to deficiency of Iodine?
Akhilesh ? Apr 1 '25 at 20:40
correct answer is: option c [Goitre]
Explanation: Goitre is a disease caused by iodine deficiency, leading to the enlargement of the thyroid gland. Iodine is essential for the production of thyroid hormones, which regulate metabolism. When iodine is deficient, the thyroid gland enlarges in an attempt to capture more iodine from the bloodstream, resulting in goitre.
- Option a: Rickets is caused by a deficiency in vitamin D, calcium, or phosphate, not iodine.
- Option b: Scurvy is caused by a deficiency in vitamin C, not iodine.
- Option d: Growth retardation can be caused by various factors including malnutrition and hormonal imbalances, but it's not specifically and directly linked to iodine deficiency in the same way as goitre is. While severe iodine deficiency during development can contribute to impaired growth, goitre is the most direct consequence.
The function that is not influenced by estrogen is

Correct answer is: option b (Formation of sperms)
Explanation: Estrogen is a primary female sex hormone. Its effects primarily target female reproductive tissues and secondary sexual characteristics. Sperm formation (spermatogenesis) is a process controlled by hormones like testosterone and follicle-stimulating hormone (FSH) in males, making it independent of estrogen's direct influence.
- Option a: Release of eggs from the ovaries is called ovulation, which is heavily regulated by hormonal fluctuations, including a surge in estrogen levels.
- Option b: Sperm formation is a process controlled by hormones such as testosterone.
- Option c: Breast development during puberty and throughout a woman's life is significantly influenced by estrogen.
- Option d: The menstrual cycle is a recurring cycle of physiological changes in the female reproductive system driven by the interplay of hormones like estrogen and progesterone.
Which is the shortest part of small intestine?
Akhilesh ? Apr 1 '25 at 20:39
correct answer is: option a (Duodenum)
Explanation: The duodenum is the shortest, widest, and most fixed part of the small intestine. It is approximately 25-30 cm (10-12 inches) long. The jejunum is the middle section, about 2.5 meters long, and the ileum is the final and longest segment, measuring about 3 meters.
- Option a: Duodenum is the shortest part of small intestine.
- Option b: Jejunum is longer than the duodenum.
- Option c: Ileum is the longest part of the small intestine.
- Option d: Since duodenum is the shortest segment of small intestine, none of the above is wrong.
