The correct answer is (c) They show which part of the brain are involved in specific activities. 
The functional  magnetic resonance imaging is used to measure the activity of brain by the detecting the change in the blood flow. This is done because the cerebral blood flow is associated with the neuronal activation. The functional area of brain has a higher blood flow that can be observed in functional MRI. The commercial application of functional magnetic resonance imaging is used in lie detectors. This technique is also used in research world and in some clinical trails. Physicians use this technique to see how risky a brain surgery can be. It is also used to learn how a normal, diseased, or injured brain functions.

Answer: If you have an excess of enzyme but not enough substrate, the reaction will be limited by the substrate availability. 
Explanation: Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product.
