which migrate to the salivary glands and wait for the mosquito to get hungry.The next puncture of a human's skin puts the sporozoites into the human bloodstream. They are carried to the liver, where they reproduce asexually. After a week or more, the parasites emerge from the liver in their next form, called merozoites, which invade red blood cells. More asexual replication occurs, with ...

We also can't see infrared, the 60 percent of light at the other end of the spectrum.

He brought back the skin and bones to the St. Petersburg Museum, and there, naturalists found that it was not exactly an ordinary horse but was a separate species.Since the explorer's name was Nikolai Przewalski (pronounced "per-zhe-WAHL-skee"), the animal was named Przewalski's horse. Whereas ...
