Lye treatment is done to remove the bitterness of the olive. Olives contain oleuropein (after their botanical name Olea europea), and it is this substance (a compound called a glucoside) that makes them too bitter to eat directly from the tree.n order to produce edible olives, harvested olives are cleaned and then cured in a natural brine of salt, oil, and flavorings or artificially with lye. For green olives, the salinity is increased by 2% every two to three weeks from the initial salinity of 12-14%.
A giraffe rests by lying with its body on top of its folded legs. To lie down, the animal kneels on its front legs and then lowers the rest of its body. To get back up, it first gets on its knees and spreads its hind legs to raise its hindquarters.
Caterpillars also sleep after they begin metamorphosis from caterpillar into butterfly. Once they are hanging by thread they have produced, the caterpillar rests until the pupa stage begins. Once this has occurred, they sleep until the pupa stage develops into the chrysalis.
