Feliz [49]

Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the extracellular fluid is called <u>transcellular transport</u>.

The two routes of transport of substances across the epithelium of the gut are by transcellular method and paracellular method.

Transcellular transport refers to the transport of solutes across a epithelial cell layer through the cells.  The best example is the movement of glucose from the intestinal lumen to the extracellular fluid by the epithelial cells. The epithelial cells use the active transport to generate the transcellular transport. Active transport refers to the transport of substances from a region of its lower concentration to a region of its higher concentration against the concentration gradient using cellular energy.

Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.

Why does our tongue get to stick to ice?
ivanzaharov [21]
Because the pole absorbs the heat quite readily, literally sucking the warmth from your tongue faster than your body can supply it. The saliva on your tongue then freezes (provided it is below freezing), with the resulting ice latching onto the flagpole and your very porous tongue.

Hope that helps you w/ ur question:)
