Consider statements about human physiology: 1. The stomach secretes acid for digestion. 2. The small intestine is the main site of absorption. 3. The liver produces bile. Which are correct? MCQ with Answer and Explanation

Explanation:
Transgenic organisms (plants or animals) have been genetically modified to contain and express foreign DNA (a transgene) from another species. Cloning is a technique used to produce genetically identical copies of a biological entity, such as a cell, organism, or DNA sequence. Gene therapy is an emerging technique aimed at treating or curing genetic diseases by introducing functional genes, but it is still largely experimental and does not currently cure all genetic diseases. Thus, statements 1 and 2 are correct.

Explanation:
In cymose (definite) inflorescence, the main axis ends in a flower, limiting further growth, and lateral branches develop below it, which also end in flowers. Racemose is indeterminate with apical growth continuing. Spike and umbel are types of racemose. Cymose includes cymes.

Explanation:
Lymphatic filariasis, commonly known as elephantiasis, is a parasitic disease caused by nematode worms, primarily Wuchereria bancrofti. The infective larvae (microfilariae) are transmitted to humans through the bite of an infected female Culex mosquito (primarily Culex pipiens fatigans). The adult worms lodge in the lymphatic vessels, causing severe inflammation, blockage, and the characteristic massive swelling (elephantiasis) of the limbs and genitals. Anopheles transmits malaria, Aedes transmits dengue.
