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.
Giraffes only sleep around 20 minutes or less per day, according to PBS Nature. Staying awake most of the time allows them to be constantly on alert for predators. They usually get their sleep in quick power naps that last just a couple of minutes. Every giraffe has two hair-covered horns called ossicones. Male giraffes use their horns to playfully fight with one another. They also spar by swinging their heads at one another and entwining their necks, which is called necking.
