Consider statements about plant biology: 1. Phototropism is growth towards light. 2. Geotropism is growth in response to gravity. 3. Thigmotropism is growth in response to water. Which are correct? MCQ with Answer and Explanation

Explanation:
Dairy farming is the business of breeding, raising, and managing dairy animals (like cows and buffaloes) for the production of milk and milk products. Poultry farming involves the commercial raising of domesticated birds (like chickens, ducks, and turkeys) for the production of meat and eggs. Apiculture is the scientific rearing of honeybees (Apis species) for the production of honey, beeswax, and other hive products; silkworm rearing is sericulture. Thus, statements 1 and 2 are correct.

Explanation:
The medulla oblongata contains vital centers that control involuntary functions like heart rate, breathing, and blood pressure. The cerebrum is responsible for memory, intelligence, and voluntary movements; the cerebellum coordinates balance and movement; the hypothalamus regulates body temperature, hunger, and hormone secretion.

Explanation:
Cerebrospinal Fluid (CSF) is a clear, watery fluid that circulates through the ventricles of the brain, the central canal of the spinal cord, and the subarachnoid space. It provides mechanical protection (cushioning), chemical stability, and waste removal for the central nervous system. CSF is primarily produced by the choroid plexus, which is a network of highly vascularized, specialized ependymal cells located within the ventricles of the brain (lateral, third, and fourth ventricles).
