Since Mary has a Type A blood, she is either AA or AO while John is either BB or BO. Since both John's parents are Type AB, he can only have the either A or B as an allele and not O so he is BB. Since John can only give the B allele, all of his children must have the B allele in their blood types. So the adopted one is the child with type A blood.

The Case of the Missing Mass: Students have completed the experiment of combining vinegar and baking soda. They notice that thei
enot [183]
The law of conservation of mass states that atoms cannot be created not destroyed, so they could not have destroyed it. This means that the experiment had to be open (which means there is no barrier that keeps all the solution in, like a plug or a bag). When the liquid in the equation turned into gas, the gas floated away from the solution, making the ending mass smaller than the beginning.
