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.
To graze on that many leaves, giraffes usually spend 16 to 20 hours per day standing and walking. Amazingly, giraffes don't need much sleep despite their long days of exercising and eating. They often only get 30 minutes to 2 hours of sleep every 24 hours from the short naps they take throughout the day.
