Answer:
Makali may produce only small amounts of a non-mutated (wild-type) GALT enzyme.
Makali may have normal amounts of GALT, but the enzyme may be mutated.
Explanation:
Makali is lactose intolerant because of his ancestry. Because of this he is not able to digest any lactose which indirectly protected him from galactosemia. Thus he must avoid consuming galactose. He has a low GALT or galactose 1‑phosphate uridylyltransferase activity. He has a normal amount of GALT and may produce only small amounts.
Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.
When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.
