The condition caused by the accumulation of uric acid crystals in joints is:
A. Osteoporosis
B. Osteoarthritis
C. Gout
D. Rheumatoid arthritis
Answer: Option C
Solution (By JKSSB Mock Tests)
Gout is a form of arthritis resulting from hyperuricemia and deposition of monosodium urate crystals in joints, causing intense pain and inflammation. It is often diet-related. Rheumatoid arthritis is autoimmune, osteoarthritis is degenerative, osteoporosis is loss of bone mass.
Explanation:
Guttation is the exudation of water droplets containing dissolved minerals from hydathodes at leaf margins, driven by root pressure when transpiration is low. Transpiration is vapor loss, bleeding is sap from cut tissue.
Explanation:
Stomatal transpiration, which occurs through the stomata (pores) on the leaf epidermis, accounts for about 90% of the total water loss in plants. Cuticular transpiration occurs through the waxy cuticle and is minimal. Lenticular transpiration occurs through lenticels in woody stems and is also very small.
Explanation:
Ovulation is triggered by a sudden and massive surge in Luteinizing Hormone (LH) from the anterior pituitary, typically around the 14th day of a 28-day cycle. This LH surge causes the mature Graafian follicle to rupture and release the secondary oocyte. FSH stimulates follicular growth earlier in the cycle. Estrogen peaks just before the LH surge, and progesterone peaks after ovulation during the luteal phase.
