Final answer:
Increased heart rate and increased salivation would be the set of effects seen with increased activity of the autonomic division of the nervous system. Hence, d) is correct.
Step-by-step explanation:
The increased activity of the autonomic division of the nervous system would result in increased heart rate and increased salivation. This is because the autonomic division has two main branches: the sympathetic division and the parasympathetic division.
The sympathetic division is responsible for the fight or flight response, which involves increasing heart rate to pump more blood to the muscles and increasing salivation to prepare for digestion. Therefore, option d. increased heart rate and increased salivation would be the set of effects seen with increased activity of the autonomic division.
