Answer:
I am assuming that the mutant cells have mutated beta galactosidase activity hence the relative levels of enzymatic activity would be reduced.
Answer:
C. the medulla oblongata, which is in contact with cerebrospinal fluid, monitors pH and uses this measure to control breathing.
Explanation:
The central chemoreceptors are located near the medulla inside the blood-brain barrier. When CO2 in cerebrospinal fluid increases, pH of the fluid lower (because CO2 becomes hydrated to carbonic acid). Change in pH stimulates the central chemoreceptors to activate respiratory centers which will increase the respiratory rate and depth of breathing.
If we don't drink water, we will not be able to flush out our waste. Dehydration could cause headache, fainting, death.
