Eukarya. This is because their cells all have a nucleus. While prokaryotes like archaea and bacteria don't have one, eukarya have a nucleus.
Going upward from the surface, it is the point where air ceases to cool with height, and becomes almost completely dry. More formally, the tropopause is the region of the atmosphere where the environmental lapse rate changes from positive, as it behaves in the troposphere, to the stratospheric negative one. Following is the exact definition used by the World Meteorological Organization:
The boundary between the troposphere and the stratosphere, where an abrupt change in lapse rate usually occurs. It is defined as the lowest level at which the lapse rate decreases to 2 °C/km or less, provided that the average lapse rate between this level and all higher levels within 2 km does not exceed 2 °C/km.<span>[1] for example</span>
The light will not light up,
; the circuit is incomplete
Also I consider this physics and electronics
Maybe it’s not a mineral because it’s just hardened tree resin whereas minerals can be mined and found deep in the earth…?
