Can you give examples of animals with exoskeleton?
@Danika answered “cockroaches, crabs, shrimps”, which is right. @Ling01 answered “spider”, which is also correct.
An exoskeleton is an external, outer skeleton - contrary to an endoskeleton, an inner skeleton (as in humans). What we call a shell, of for instance a crab, is an exoskeleton. However, all exoskeletons are not that large and clear.
One person in the history of France, was as well emperor as president – although not at the same time – who was that?
@Tomi-Ajax answered Napoleon. I had to ask him to specify that answer because Napoleon can be both right and wrong. I came to the conclusion that he meant the wrong Napoleon, so his answer was wrong. It was not THE Napoleon, or Napoleon I. However, it was his nephew, Louis-Napoléon Bonaparte, as an emperor known as Napoleon III. He was a president 1848-1852, and an emperor 1852-1870.
Wimbledon, the world's most prestigious tennis tournament, opened up for professional players in 1968. The time that followed, and still continues, is called Wimbledon's Open Era; that is the time after 1968.
So, after 1968, which player was the first to reach 5 Wimbledon victories?
It was Swedish tennis player Björn Borg, who won Wimbledon 5 consecutive years from 1976 to 1980.
“Frogs are often said to lack teeth, but that is not entirely correct. They have "maxillary teeth", set in the upper jaw. Some of them have vomerine teeth which are very small palatal teeth. Frogs do not cut or chew, their concern is for holding a prey while swallowing it. Toads, however, are lacking teeth altogether.”
What is the Korean version of the Chinese yin-yang symbol called?

There are many fans of horror at this platform; let's ask about two real horror classics. Most people are familiar with the names Frankenstein and Dracula.
Who (or what) were they? (Think carefully before you answer, because here lies a trap.)
Normally cats, big and small, are solitaires. That is to say, they live their lives alone, except when mating or for females having babies. One of the big cats, however, is genuinely social – which one?
