Answer:
The synthesis of an amino acid follows this pathway: precursor A → intermediate B → amino acid C. Each reaction is catalyzed by a different enzyme. This metabolic pathway is controlled by feedback inhibition with amino acid C inhibiting the conversion of precursor A to intermediate B. Amino acid C acts as a noncompetitive inhibitor of the first enzyme in the pathway.
Explanation:
A no-competitive inhibitor reduces the activity of an enzyme by binding at its active site although it has already bound to the corresponding substrate
Amino acid C acts as a noncompetitive inhibitor, regulating its own production via feedback inhibition. This is a common mechanism used in metabolic pathways to maintain balance.
In the described pathway, amino acid C regulates its own production by inhibiting the first step of the pathway. This is an example of a regulatory mechanism called feedback inhibition. Essentially, when there's plenty of amino acid C present, it will bind to the first enzyme in the pathway, preventing its action and thus stopping more of amino acid C from being produced. So, in this scenario, amino acid C is acting as a noncompetitive inhibitor of the first enzyme in the pathway.

B. friction between the ocean and wind on its surface
C. ocean movements associated with earthquakes
D. changes in water density
Answer: B. friction between the ocean and wind on its surface
Explanation:
The water in the ocean surface is influenced by the winds that blows in the certain patterns because of the spinning of the earth at different angles. Wind currents are capable enough to influence the water tides and motion of surface layer of water. Therefore, B. friction between the ocean and wind on its surface is the correct option.
The layer of solid ground that makes up all of Earth’s continents is called the Lithosphere. Thus, the correct option for this question is A.
The lithosphere may be defined as the rigid and outer part of any celestial body like earth. The lithosphere of the earth significantly includes the brittle upper portion of the mantle and the crust along with the outermost layers of Earth's structure.
In the region of the lithosphere, the rocks are cooler, stronger, and more rigid as compared to the other parts of the earth's surface. It is the strength of the rock and the existence of the continents that differentiated the lithosphere from other parts.
Therefore, the lithosphere is the layer of solid ground that makes up all of Earth’s continents. Thus, the correct option for this question is A.

B. Your mass is too low.
C. Mars is a larger planet than Earth.
D. Mars is a long distance away.
The correct answer is option D. Mars is a long distance away.
According to the universal law of gravitation, the effect of the force of gravity decreases as the distance increases. The gravitation force is inversely proportional to the radius or the distance. So, the gravitational force exhibited by the Mars is not experienced by us due to the large distance.
