What happens in the artificial transmutation of an element? included an example.

In artificial transmutations the nucleus is bombarded with high-energy (kinetics energy) particles to induce transmutation. There are two reactants or the nucleus that is being bombarded and the high-energy particle. 

High-energy particles are accelerated in accelerators, by the application of electric and magnetic fields. Neutrons cannot be accelerated in accelerators using electric and magnetic fields because their charge is 0. 

I hope my answer has come to your help. God bless and have a nice day ahead!

The answer is d because i just took the test

Organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
