The first one. Gametes are the reproductive cells: sperm and egg cells. These contain the info that is passed on to the offspring, so an inherited mutation must be present in the gametes.
        
                    
             
        
        
        
  The element  that  is  likely  to form a ionic  bond  with potassium is  Cl  (answer A)
<em><u>Explanation</u></em>
 Ionic   bond  -  is a  bond formed  when  a  metal  and  a  non metal react.
Metal  loses  electron ( donate  electrons)  while  non metal   gains  electrons  ( accept  electrons)  to form  ionic  bond.
potassium  is a metal   while Chlorine(Cl)  is a non  metal.  They  react  to form an  ionic  bond   by potassium  donating  1 electron  while  chlorine accept 1 electron.
