A biological cycle, or rhythm, that is approximately 24 hours long is called a circadian cycle
It is a matter of time. Crystallization processes can occur more easily when the rock is kept at a certain temperature during a long time. Because of that, well-formed and well crystallized minerals will appear in intrusive igneous rocks (such as granitoids). On the opposite, when a rock spreads rapidly over the Earth's surface, the temperature decreases rapidly, keeping the minerals from forming. A homogeneous paste will form, without any (or few) minerals in it. It is the case for volcanics rock
<span>The amount of genes we have is considered an estimation. They
used to believe it was around or above 100,000. Then when the human genome project (HGP)
was completed in 2003 their estimation brought it down to 20,000 to 25,000. You
can find their current work at “national human genome research institute” and
also a free public database. </span>
The gas form of water is water vapor.
