particles‚ mucus clearance is an essential mechanism to remove the foreign particles‚ such as dust‚ bacteria‚ viruses and other potential pathogens‚ and to keep our airways and lungs clean and free of obstruction. An important mechanism for clearing mucus involves moving water across the membrane‚ out of the cell‚ into the mucus. This movement of water is a result of chloride and sodium transport across the membrane. This method‚ along with other mechanisms is what ensures fluidity of the mucus‚ resulting

Selective breeding in dogs. Also known as artificial selection‚ is the process by which humans use animal breeding and plant breeding to develop particular traits on the animals such as how they look or to produce certain exaggerated traits. There are many different types of traits that make reason for selective breeding‚ mainly physical‚ and only some for good emotional and disease blocking purposes. In a lot of ways‚ this is similar to inbreeding in humans. Selective Breeding a bad thing because

advantages of road transport in comparison to other modes of transport. 1. Less capital quality:- Road transport required much less capital investment as compared to other modes of transport such as railways and air transport. 2. Door to door services: - The outstanding advantage of road transport is that it provides door to door or warehouse to warehouse services. 8. Saving in packing cost: - As compared to other modes of transport‚ the process of packing in motor transport is less complicated
