Answer:
The correct answer will be option-thick bundles of fibers that allow communication between the brain’s hemispheres. 
Explanation:
Cerebral commissures are the thick fiber tract composed of white matter which connects the same cortical areas of the left and right hemispheres of the brain.
Commissural fibers include many types of fibers in which corpus callosum fibers are one of the types of fibers which act as the main Cerebral commissures.
Since these fibers connect the two hemispheres, therefore, they help in the communication between two hemispheres.
Thus, the selected option is the correct answer.

Answer:
Bio carbonate ions
Explanation:
The pancreas secrets an aqueous mixture ( water, digestive enzymes and bicarbonate ions) during digestion of food substances from the stomach into the duodenum to begin the process of absorption and assimilation.
The pancreatic duct are lined with duct cells. These are cells which secretes HCO3- ,into the aqueous mixture. This ion is basic. Therefore it  neutralizes the acidity of the  of  the chyme to  released from the stomach to enable the pancreatic enzyme to work.
The bicarbonate ions also prevent the walls of the pancreases from getting burnt by the effect if the acidity of the chyme.
