RNA viruses can copy themselves which is harder for scientists to give an accurate conclusion to solve them.
Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds. Covalent compounds have bonds where electrons are shared between atoms.
It can be inferred that muscle cells in athletes produce more ATP than muscle cells of those who live sedentary lifestyles.
