The diaphyses and the epiphyses of long bones remain separated by a growing zone of cartilage (the metaphysis ) until the child reaches adulthood (18 to 25 years of age), whereupon the cartilage ossifies, fusing the two ...

Most eggs live inside of the fruit along the peel of the fruit. "Some feed on other decaying organic matter or on plant exudations; ...

Warm-blooded

Endosymbiotic theory

... been considered, although they lack DNA. Christian de Duve proposed that they may have been the first endosymbionts, allowing cells to withstand growing amounts of free molecular oxygen in the Earth's atmosphere. However, it now appears that they may be formed de novo , contradicting the idea that ...

Enzymes and health Enzymes are essential to living organisms, and a malfunction of even a single enzyme out of approximately ...

Among the parasitic fungi are species which are insectivorous or helminthivorous (worm-eating). Some insectivorous ...

This "specificity" phenomenon may explain why transmission of prion diseases from one species to another (such as from sheep to cows or from ...
