They are nocturnal, and thus people cannot see them during day time. The naming of earthworms is due to their common occurrences in unpolluted cultivated lands where piles of fecal casting can be seen at the mouth of a tunnel they live in. T..." current

Milk is converted into Dodhi due to the fermentation of lactose, the carbohydrate present in milk, by some special types of bacteria. Doi can be made by coagulating milk by adding starter culture at 2-3% to lukewarm milk and keeping it at 37-42°C temperature for 4-12 hours. In general, dodhi made before 2-3 days is considered a starter culture rich in beneficial bacteria. The carbohydrate in milk..." current

All living things contain DNA within their cells that hold the genetic instructions. In eukaryotes, most of the cellular DNA is located within a membrane-bound structure called the nucleus (which is referred to as nuclear DNA), but the mitochondria may also contain a small amount of DNA (which is referred to as mitochondrial DNA or mtDNA). In contrast, in prokary..." current
