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.
Answer:
The result of a collision between continental plates in which one plate is forced down toward the heat of the mantle creating sedimentary rock. :)
There is reaction with A but no reaction with anti-B, so blood is type A.
If it reacts with anti-rh, it is rh-positive.
So blood is type A rh-positive.
Answer:
Microglial cells
Explanation:
Microglial cells are one of the various types of neuroglial cells in the central nervous system. Microglial cells are the small cells and have thin slender processes. Many spine-shaped outgrowths come out of these processes. Microglial cells serve as phagocytes of the central nervous system. These cells clean the cellular debris that is generated during the normal development of the nervous system. Microglial cells also perform phagocytosis of microbes and damaged nervous tissue.
Answer:
It's the nature vs nurture situation. While the genetics of a person does control the physical traits he/she may develop, the environment also has a major role to play here. For instance, the person may have the genes for developing a tall height. If, however, that person is not provided with the right kind of nutrition and the right time, it is very likely that he/she will not grow as tall as they had the potential for. Similar explanation for non-physical traits.
This is not an 'either/or' type of argument. Genetics and the environment have a collective impact in shaping the person into who they are and while the balance may shift to one side or the other in certain cases, it does not cancel out or negate the other's effect.
Hope that answers the question, have a great day!
