Deep canyons, steep cliffs, rugged mountains. Dry, rocky environment. Little rainfall so few trees. Influenced the kinds of homes built. (Used stones, mud, bricks, etc.)

Hemophilia is a X-linked recessive trait. I will denote it as XA for dominant and Xa for recessive.
Hemophilic male: Xa Y
Carrier female: XA Xa
Cross:
Xa Y
XA XaXA XAY
Xa XaXa XaY
Thus, as shown, of the ratio of two possible female offspring genotypes for Hemophilia, only 1/2 will have the disease; the chance is therefore 50%.
The ratio for male offspring genotypes for Hemophilia is 1/2 as well; the chance is therefore 50%.
Answer:
Ecosystem.
Explanation:
Archaea play an important role in ecosystems with organisms that derive or produce energy from oxidation of methane. Many of Archaea are bacteria which are often a major source of methane in such environments and they can play a role as primary producers. Archaea is important for scientists because it has unique ecological roles and can also generate energy differently i.e. responsible for producing biological methane which no eukaryotes or bacteria can do that.
