Animals classified as extinct in the wild still survive, but only in human care or outside their native range; no known wild population remains in their natural habitat. The category is a formal conservation status, not a claim that every individual of the species has died. What “extinct in the wild” means The International Union

Water evaporation is the process by which liquid water changes into water vapor, a gas, and enters the air.

What water evaporation means Evaporation is

Yes—GA3, or gibberellic acid, can speed germination in some seeds by helping overcome dormancy and promoting the growth of the embryo. It is not a universal germination booster: results depend on the plant species, seed condition, treatment, and growing conditions, and some seeds gain little or no benefit. What GA3 Is and Why Seeds Need
