Which of the choices below describes the pathway of cellular respiration (the complete oxidation of glucose)?

A. Decreased urine volume: ADH increases water reabsorption in the collecting ducts, leading to less water in the urine and decreased urine output.
B. Decreased urine molarity: ADH leads to more concentrated (higher molarity) urine, not less.
C. Increased urine volume: ADH reduces urine volume, not increases it.
D. Increased urine salinity: ADH affects water, not salt. Salinity may change indirectly, but this is not a direct effect.
E. Increased urine acidity: Urine acidity is influenced by hydrogen ion excretion, not directly by ADH.

A. The voluntary phase of swallowing takes place within the mouth: The oral phase is under voluntary control and involves tongue movement to push the bolus to the oropharynx.
B. The epiglottis assists in propelling food into the trachea: This is incorrect. The epiglottis prevents food from entering the trachea by covering the glottis during swallowing; it does not propel food.
C. The involuntary portion of swallowing takes place in the pharynx: After the oral phase, swallowing becomes involuntary, involving reflexive contractions of pharyngeal muscles.
D. The mouth, pharynx and esophagus all take part in swallowing: All three structures are involved in the three phases of deglutition: oral, pharyngeal, and esophageal.
