This biome has a layer of soil that can either be sandy, gravelly, or stony, depending on the type of desert. Deserts usually get at most 50 centimeters (20 inches) of rainfall a year, and the organisms that live in deserts are adapted to this extremely dry climate. Plants in deserts have adaptations to conserve water.
<span>The nurse would need to consult the beers criteria prior to giving medications to patients who fall in the category of elderly.

the killer whales would die of starvation as they would have no source of food, and the cod would become overpopulated. The krill would be scarce, and the algae would over grow.
I hope this helps
Chemosynthesis is the biological conversion of one or more carbon- containing molecules.
The plasma membrane is the biological membrane that separates the interior of the cell from its external environment. It is selectively permeable in nature and allows the transport of substances in and out of the cell either by passive transport or active transport.
Passive transport is the movement of substances from a region of their higher concentration to a region of their lower concentration through a semi-permeable membrane. Substances like carbon dioxide and oxygen move across the plasma membrane by diffusion which is a type of passive transport. It involves the diffusion of carbon dioxide down its concentration gradient. Carbon dioxide and oxygen are two molecules that undergo the process of simple diffusion across the plasma membrane.
