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.
Answer: The difference between structures of glucose and galactose occurs at a carbon other than the anomeric carbon.
Explanation: The cyclic structure of glucose and galactose is cannot be inter converted because the change does not occurs at the anomeric carbon.
It takes place at carbon number 3 ( Fisher's projection)which does not takes place in the opening and closing of the rings.
Anomeric carbon are the carbon that takes place in the opening and closing of the rings.
