Fossils, or preserved parts of organisms from the distant past, have shown that species change over time. Radiometric dating can be used to determine the age of fossils by measuring the how much of the radioactive materials in each rock layer have broken down.
Without it, there are no stars, including our own sun, and there wouldn’t be us talking about it.
It is used in particularly destructive bombs.
At a tiny scale, it can be used to produce neutrons, eg, a Farnsworth Fusor.
At a large scale, we have yet to figure out how to make controlled fusion work in a way that runs for a long time and generates collectible power we can use to feed the process. This has remained elusively 20 years out from the current state of affairs for 50 years.
If it was made to work, then it would probably be a good source of clean energy that would be safer than many of the non-renewable alternatives.
I don’t expect to live to see it happen.
In the G2 phase the cell is prepping and has reached various checkpoints so that it can divide
cause an increase in the rate of certain mutations
