The plant that exhibits 'insectivorous' nutrition to obtain nitrogen is:
A. Cuscuta
B. Monotropa
C. Loranthus
D. Nepenthes
Answer: Option D
Solution (By JKExamLibrary)
Nepenthes (pitcher plant) is an insectivorous plant that traps insects in its modified leaf pitchers to supplement nitrogen in nutrient-poor soils. Cuscuta is parasitic, Loranthus partial parasite, Monotropa saprophytic.
Consider statements about animal husbandry: 1. Artificial insemination improves cattle breeds. 2. Multiple Ovulation Embryo Transfer is used in poultry. 3. Crossbreeding combines traits of two breeds. Which are correct?
Explanation:
Artificial insemination allows the use of superior bull semen to improve cattle genetics widely. Multiple Ovulation Embryo Transfer (MOET) is a technique used in cattle and other mammals to increase herd improvement rates, not in poultry (which uses hatching eggs). Crossbreeding involves mating animals of different breeds to combine desirable traits and exploit hybrid vigor. Thus, statements 1 and 3 are correct.
Explanation:
Ovulation is the process in the female menstrual cycle where a mature ovarian follicle ruptures and discharges an ovum (secondary oocyte) into the fallopian tube, where it can potentially be fertilized. It typically occurs around the 14th day of a 28-day cycle, triggered by a surge in Luteinizing Hormone (LH).
Explanation:
The colon (large intestine) reabsorbs water, electrolytes, and vitamins produced by gut bacteria, compacting the indigestible residue into feces. The small intestine absorbs nutrients, stomach digests, esophagus transports.
