Leopards and cheetahs look very similar, since both have spotted coats, but the two species of big cats are actually quite diffe
rent. Leopards are usually bigger than cheetahs, and they are typically more aggressive. Unlike cheetahs, which hunt small mammals in groups, leopards hunt alone, and while they eat anything from insects to antelope, leopards can catch animals weighing as much as 400 pounds. Cheetahs are relatively comfortable around humans and have even been kept as pets, while leopards have occasionally been known to attack humans unprovoked. Which inference is best supported by the details in the text? A. Leopards are better hunters than cheetahs. B. Cheetahs are smaller than leopards. C. Leopards are more dangerous than cheetahs D. Leopards work together to drag their prey into trees.
This is because the urea molecule has an oxygen atom bound with double bonds to the central carbon atom, and this oxygen can form a hydrogen bond with water, as well as both terminal amine groups that can also form a hydrogen bond each because of the lone pair of electrons on the nitrogen group.
