Boron's atomic number is 5, so for its 5 protons, it should have 5 electrons if it's neutral.
To make it an ion, Boron's charge would have to be negative or positive. It could lose one electron to have a charge of +1, gain an electron to be -1 ion.
Ions aren't at specific number. So the answer depends on Boron's tendency to gain or lose electrons.
        
             
        
        
        
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. They all have the same basic pattern of bones. They inherited this pattern from a common ancestor. However, their forelimbs now have different functions
        
             
        
        
        
Answer:
Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. This can involve either aerobic or anaerobic micro-organisms that often use this breakdown as an energy source.
