Describe facilitated diffusion of ions through the channel proteins
Amiraneli [1.4K]

Facilitated diffusion is usually significant to pass the ions across the hydrophobic layer of the plasma membrane. Transmembrane integral protein and careers proteins provide the channels that allow the ion to pass across the membrane.  When an ion bind to their active site on the protein (note that the proteins are very selective), the protein changes conformation. It is this change in conformation opens up the channel that allows the ions to be passed across the membrane. When the ions are released inside of the cell, the protein resumes normal shape (and the channel also closes) and the active site becomes available again or another ion.

If the planet were to cool in the future, snow may begin to accumulate in the head of a glacier more rapidly than it would melt
Phoenix [80]

Answer:

The glaciers will accumulate more in amount when the planet cools, and this will result in the slow expansion of glaciers, extending horizontally and downward, due to the pressure exerted by the glaciers. The glaciers will be rapidly accumulated in the glacier head in comparison to the zone of wastage, which covers the region below the snowline.  These glaciers moves at a fairly slow rate, under the influence of gravity.

As the planet cools, the terminus of the glaciers (glacier end or toe) will expand and will be distributed more outward and downward, and there will be more quantity of snow in a cool planet.
