OLga [1]
Loop Diuretics

These are diuretics that exerts effect on the loop of Henle.  They are primarily used in heart failure, hypertension and edema. In contrast with Thiazides, loop diuretics are more  effective in patients with abnormal kidney function. Loop diuretics inhibit the magnesium and calcium reabsorption in the thick ascending limb of Henle. Loop diuretics is highly protein bound. It has volume of distribution that is limited.

Can someone help me with facts about rainforests? I have to do a project and I'm stumped.
jeka57 [31]
Rainforest cover only 2 % of the total surface area of the Earth but in spite of that about 50 % of plants and animals that live on the Earth live there.

By definition rainforests are forests that recieve high amounts of rainfall so you can actually find rainforests in Alaska for example (other examples: Canada, Asia, Africa, Latin and South-America)

About 1/4 of natural medicines are found in rainforests. 70 % or more of the plants that are used to treat cancer are found only in tropical rainforest on the planet.

Trees in tropical rainforests are so dense that it takes approximately 10 min for the rainfall to reach the ground from canopy.
