2014年4月2日 · Filtration is used to separate a solid from a liquid in which it is suspended. Filtration is also used to separate a substance from a mixture because one is insoluble in the solvent and the other is soluble.the separation is due to particle size. 3.for example the separation of sodium chloride from a mixture of sodium chloride and sand.

2015年12月2日 · Filtration is the movement of a fluid (mixture of several molecules) from a region of high pressure to a region of a low pressure. Biology Science

2015年11月4日 · The hydrophobic tails of the phospholipids prevent the polar molecules to pass in the cell or substances like glucose and proteins to pass out of the cell. The big molecules are also restricted to pass through the bilayer. However, these restricted molecules pass in or out via membrane proteins in a managed way.

2016年9月20日 · The main function of the glomerulus is to filter plasma and produce glomerular filtrate , which passes through the length of the nephron tubule to form urine. Urine formation begins with glomerular filtration, which is a non selective process in which fluids and solutes are forced through a membrane by hydrostatic pressure. The factors determining the permeability …

2015年9月21日 · See below. > Filtration is the separation of a solid from a fluid by passing the mixture through a medium through which only the fluid can pass. In gravity filtration, a suspension of a solid in a liquid is allowed to flow by gravity through a porous medium such as a filter paper. The liquid passes through the pores in the paper, and the solid is retained on the paper. …

mixtures can be separated using various separation methods such filtration,separating funnel,sublimation,simple distillation and paper chromatography. The methods stated above are all physical methods. There are also chemical methods, which are used by rearranging the particles so a certain substance no longer exists (chemical reaction).

2018年3月6日 · small volume of liquid left in beaker or filter paper Filter paper (if that's what you used) "traps" and could have evaporated some fluid in it. So not all your fluid was collected in the filtrate which means the mass would be smaller. You could also argue that when tilting the beaker, there's always those tiny little droplets left behind in the beaker since they stick to the wallls, …

2017年5月19日 · Red Blood Cells, due to their large size. The glomerulus is a meshy network of capillaries at the start of the nephron in our kidneys. They are the first step in blood filtration, as substances can go through the capillary endothelial cells, basement membrane, and finally podocytes into Bowman's Capsule to be filtered outside the body. This filtration process relays …

2017年12月23日 · Reabsoprtion occurs next to filtration. In this process, several components of the glomelular filtrate that are vital for body functioning are transferred back to the blood. It takes place in PCT, Loop of henle, DCT and collecting duct. Proximal convoluted tubule: Here maximum reabsorption of filtrate contents takes place.

2015年10月31日 · In a number of different ways, depends on the components of the mixture that you are trying to separate.
