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 and Dry Deserts temperature ranges from 20 to 25Â° C. The extreme maximum temperature for Hot Desert ranges from 43.5 to 49Â° C. Cold Deserts temperature in winter ranges from -2 to 4Â° C and in the summer 21 to 26Â° C a year. The precipitation in Hot and Dry Deserts and the precipitation in Cold Deserts is different. Hot and Dry Deserts usually have very little rainfall and/or concentrated rainfall in short periods between long rainless periods. This averages out to under 15 cm a year.
