The type of epithelial tissue that lines the inner surface of the stomach and intestines is: MCQ with Answer and Explanation

Explanation:
Metastasis is the process by which malignant cancer cells detach from the primary tumor, travel through the blood or lymph, and establish secondary tumors in other organs. Benign tumors do not metastasize. Apoptosis is programmed cell death.

Explanation:
Elephantiasis, or lymphatic filariasis, is caused by parasitic nematode worms, primarily Wuchereria bancrofti (responsible for about 90% of cases), Wuchereria malayi, and Brugia timori. These worms are transmitted by mosquitoes (like Culex). The adult worms lodge in the lymphatic vessels, causing severe inflammation, blockage, and damage to the lymphatic system. This leads to the accumulation of lymph fluid and massive, disfiguring swelling (edema) of the limbs, genitals, and breasts, resembling an elephant's skin and legs.

Explanation:
A balanced diet contains all the essential macronutrients (carbohydrates, proteins, fats) and micronutrients (vitamins, minerals) in the correct proportions required for optimal health, growth, and maintenance. Malnutrition is a broad term that refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients; it includes both undernutrition (wasting, stunting) and overnutrition (overweight, obesity). Water is an essential nutrient, crucial for hydration, transport, and all biochemical reactions. Thus, statements 1 and 3 are correct.
