Alan Saldivar is a healthy, active individual in his mid-thirties. One day, he was using a strong solvent to clean up spilled paint in his garage and he felt a stinging sensation in his nose. Later that day, while cooking, he burned his food on the grill because he couldn’t smell that it was burning. He also noticed he could barely taste any of the food he ate. To improve the taste of his food, he tried increasing the amount of salt in his food. After a few days of pain and loss of smell, he went to see an otolaryngologist (Ear/Nose/Throat Doctor). During the examination of Alan’s nose, the doctor reported that Alan’s nasal mucus membranes were found to be inflamed. The doctor told Alan, that his sense of smell should return within two weeks, if due to inflammation, but to return to see her if his sense of smell had not improved after that time. Two weeks later, Alan’s sense of smell still hasn’t returned. Why was Alan’s taste of food affected?

Well let's uhmmm how many bedrooms you want. if you want a garage. not to mention the price of the house?

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.
