Answer: Scientists look for cell types, the ability to make food, number of cells in their bodies.
Explanation: Scientists look for cell types, the ability to make food, number of cells in their bodies when placing newly-discovered organisms.
 
        
             
        
        
        
Explanation:
It is given that lattice energy is -701 kJ/mol.
Whereas it is known that realtion between lattice energy and radius is as follows.
                Lattice energy 
where,           = +2,    and
 = +2,    and  = -2
 = -2
Therefore, lattice energy of AB = 
                                                     = 
                                                     = -2804 kJ/mol
Thus, we can conclude that lattice energy of the salt ABAB is -2804 kJ/mol.
 
        
             
        
        
        
Well, even though it may look like the last option is the correct one, that one is wrong. When a crystal s formed from many metals there are many milecular orbitals. So the answer is B. Hope this is what you are looking for
