This is an active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.
faltersainse [42]

Answer:

Primary active transport

Explanation:

Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump  is an example  of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).

Answer:

A. The temperatures are too high.

Explanation:

A desert is a region with extremes of temperatures and little to no rainfall.

Organic matter are the remains of organisms that have died. They are a very important component of soils.

Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.

Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.
