C the presence of harmful substances in food
Answer:
α-ketoacid; glutamate.
Explanation:
The amino acid synthesis is important for all the living organism. Different organism uses different strategy for the synthesis of amino acid.
The α-ketoacid is generally used in the synthesis of amino acid especially in microorganisms and plants. The transamination of glutamate results results in the formation of particular alpha-keto acid.
Thus, the correct answer is option (b).
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.
Scientists are helping to improve understanding of how rocks in Earth's hot, deep interior enable the motions of tectonic plates, which regulate the water cycle that is critical for a habitable planet.
I think the answer is frequency if I remember correctly
