The rules of base pairing explain the phenomenon that whatever the amount of adenine (A) in the DNA of an organism, the amount of thymine (T) is the same (Chargaff's rule). Similarly, whatever the amount of guanine (G), the amount of cytosine (C) is the same.
Most food chains are limited to three or five trophic levels because the energy available is only enough for those number of trophic levels: there is insufficient energy to go round more trophic level. At each trophic level, a large quantity of energy is used to maintain organisms at that level, because of this, organisms at one trophic level, pass less energy to the ones at the next trophic level. <span />
The UV is needed by the skin to make previtamin D3. Previtamin D3 or cholecalciferol made from the skin will be changed in the liver into 25- hydroxyvitamin D3 and then sent to the kidney to be changed into 1,25- dihydroxyvitamin D3. The last change in the kidney will active the vitamin D. Vitamin D has a role in the calcium absorption which was will strengthen the bone tissue.
