Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. The nucleus of eukaryotic cells is similar to the brain of the cell. It contains the genetic information (DNA) and directs the cell how to function. What is the location and function ofRead More →

Habitat of Protozoa: Free-living forms occur in fresh water lakes, ponds, open ocean, river and even in temporary pools. Soil and sands also form natural environment for many Protozoa. … For such Protozoa that can invade unrelated host species, a change of hosts is essential for the completion of itsRead More →

The ameba can be found in: Bodies of warm freshwater, such as lakes and rivers. Geothermal (naturally hot) water, such as hot springs. Warm water discharge from industrial plants. Geothermal (naturally hot) drinking water sources. Swimming pools that are poorly maintained, minimally-chlorinated, and/or un-chlorinated. Where do amoebas live in humans?Read More →

North American coal deposits were first discovered by French explorers and fur traders along the shores of Grand Lake in central New Brunswick, Canada in the 1600s. Coal seams were exposed where rivers flowed into the lake and was dug by hand off the surface and from tunnels dug intoRead More →

All eukaryotic genomes carry introns as parts of some gene structures and the introns are to be eliminated by a complex molecular machinery called the spliceosome comprising five snRNAs and more than 150 proteins . Where are introns found in eukaryotes? For example, introns are extremely common within the nuclearRead More →
