Space observatory.
Explanation:
Space observatory uses electromagnetic radiation to discover the properties and composition of bodies in space because it is a telescope that is found in the outer space to check galaxies ,distance planets, and some other astronomical objects and it is sensitive to different electromagnetic spectrum in space and its wavelengths allow lights to get through the Earth's atmosphere.
The allele for sickle cell anemia would be an example of natural selection. In most situations, having crescent shaped red blood cells would hold less oxygen & would not be ideal. But in places that are affected by diseases like malaria, which attack red blood cells, having crescent blood cells minimizes the threat malaria can cause.
