Stem cells are the primal cells which develop from adult body tissues and embryos. These are present in the adult body through out their life. These are also called tissue specific or somatic stem cells. These are more specialised than embryonic stem cells. These stem cells are found in bone marrow, brain, blood and blood vessels, skeletal muscles, skin and the liver. Differentiation is the process where an unspecialised cell acquire cellular character which allows it to perform specialised functions. During embryonic stage, the cells of embryo make a number of cell fate decision that result in the decreasing capability eventually producing the specialised cells. Stem cells can divide and produce new cells, Hence they have the potential to be transplanted to the patient to treat medical conditions and disease. They are removed form the embryo where they exist as unspecialised stem cells and they will differentiate into any cell type. Specialised cells include many cells like nerve cells, blood cells, ovum cells etc. These specialised cells help in reproduction, energy metabolism, regeneration, information transfer etc.

Answer:
Explanation:
In Vietnam, 34.8 percent of land is dedicated to Agricultural use. In 2018, agriculture, forestry and fishing accounted for 14.68 percent of the country's GDP. Vietnam's main agricultural crops are rice, cassava, maize and sweet potatoes. The relaxation of the state monopoly on rice exports transformed the country into the world's second or third largest rice exporter. Other cash crops produced and exported are coffee, cotton, peanuts, rubber, sugarcane, and tea.
Land dedicated to agricultural use in Bangladesh is 70.1 percent. Agriculture is the largest employment sector in Bangladesh. Most Bangladeshis earn their living from agriculture. Although rice and jute are the primary crops, wheat is assuming greater importance. Tea is grown in the northeast. Because of Bangladesh's fertile soil and normally ample water supply, rice can be grown and harvested three times a year in many areas.
Survival of the fittest is a term mainly used which states that only animals that are the best adapted will survive over an evolutionary period
