The sensory, or afferent, division of the peripheral nervous system transmits information from the _________ to the CNS. skin. The interior of a nerve cell has a slight excess of negative charge because: potassium diffuses out of the cell.
The largest hot desert in the world, northern Africa's Sahara, reaches temperatures of up to 122 degrees Fahrenheit (50 degrees Celsius) during the day. But some deserts are always cold, like the Gobi desert in Asia and the desert on the continent of Antarctica. Others are mountainous.nly about 10 percent of deserts are covered by sand dunes. The driest deserts get less than half an inch (one centimeter) of precipitation each year, and that is from condensed fog not rain. Desert animals have adapted ways to help them keep cool and use less water.
Hot desert climates are generally hot, sunny and dry year-round. They rise at a higher latitude in south-western United States in the sheltered regions warmed up in winters by the Pacific Ocean, enabling searing summer temperatures in the Death Valley basin at 36 degrees latitude.
