Chromaffin cell. Chromaffin cells, also pheochromocytes, are neuroendocrine cells found mostly in the medulla of the adrenal glands (located above the kidneys) in mammals.
The Moon has no appreciable atmosphere. The sky is always black and the radiation from the Sun strikes with full force on the surface of the Moon. The lack of atmosphere produces temperature extremes on the Moon that range from -250 degrees F in the dark to +250 degrees F in the light.
The moon has no atmosphere and thus the gravity is very weak compared to Earth. The moon cannot keep gases that make up air. Also, there is no wind on the moon and the temperature varies dramatically during the course of a day from 100 degrees Celsius in the afternoon to -175 degrees Celsius at night.
