How is the concentration of h3o ions and oh- ions different in an acid solution and a basic soulution?

In an acidic solution, the concentration of H+ is greater than the concentration of OH-. The pH will be less than 7.
In a basic solution, the concentration of OH- is greater than the concentration of H+. The pH will be greater than 7.
In a neutral solution, the concentration of H+ ions to OH-ions will be equal, and will therefore have a pH of 7. (This is due to water autoionization, which we usually ignore because it is small in other circumstances.)

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab.
