When we perform a study, we test a specific hypothesis to see whether our hypothesis is supported by the data or not. If our hypothesis is not supported by the data, then we can argue that a specific argument (that would be important for this hypothesis) does not have a claim in scientific research. 
This is more broadly meant though. Usually you need to perform multiple studies and test multiple hypothesis to be able to critique a scientific argument and see whether the claims it makes and the predictions it makes hold up in scientific research. 
        
             
        
        
        
No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.

Do all living organisms have mechanisms for homeostasis?
All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity.
