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 elements sodium (Na) and potassium (K) have been detected in the Moon's atmosphere using Earth-based spectroscopic methods, whereas the isotopes radon -222 and polonium -210 have been inferred from data obtained by the Lunar Prospector alpha particle spectrometer.
Temperatures on the moon are very hot in the daytime, about 100 degrees C. At night, the lunar surface gets very cold, as cold as minus 173 degrees C. This wide variation is because Earthâs moon has no atmosphere to hold in heat at night or prevent the surface from getting so hot during the day.
