1. One reason is extinctions happen because of some kind of change in the environment where a life form lives. While some species can adapt to the changes, others die, and if enough die, the species becomes extinct. These are some of the biggest factors in the extinctions of particular species. 2. Contaminants in the environment, such as pesticides.

finlep [7]

Answer:

The correct answer is - loss of soil moisture east of mountain ranges.

Explanation:

Air or wind with moisture moves towards the top of the mountains where it precipitates and condenses before crossing the mountains and when this air crosses there is no moisture left in them to precipitate on another side.

The other side called rain shadow and is forced to become the area desert in the long run which is called the rainshadow effect. The major effect of the rainshadow effect is the formation of the deserts in a natural way.

drawing upon the results of this exercise, why is pseudomonas aeruginosa of such concern in burn patients chegg
Agata [3.3K]

Pseudomonas aeruginosa is of concern in burn patients beacuse it can cause infections like AIDS,diabetes mellitus , etc.

Pseudomonas aeruginosa is a common bacteria that can be found in soil, water, and other environmental niches. Burn wounds are intricate microenvironments where bacterial pathogens like P. aeruginosa can cause infections. Typical virulence factors like pyocyanin and pyoverdine expressed at higher levels than they would have under conventional laboratory conditions.

Elastase is secreted as well, is primarily responsible for the host tissues'  degradation. P. aeruginosa infections cause severe consequences mostly in organisms with weakened natural defences. Examples of these circumstances include burn wound patients.
