Answer:
1. vi. Preganglionic
2. vii. adrenergic
3. ii. sympathetic chain ganglia
4. iii. Craniosacral
5. viii. splanchnic
Explanation:
Action potential travel down preganglionic nerve fibre. They travel towards Vagus Nerve near the effector organ. These impulses arrive at cardiac plexus, which create action potential in postganlianic.
Answer:
Control environment is the most important procedures for getting good results.
Explanation:
The control environment for an experiment is the essential part for getting good results. In control environment, there is no or less chances of infestation from the external environment which can cause the results of the data more acceptable. So the scientists prefers laboratory for performing experiment as compared to outer environment. So in my opinion for getting better results, the control environment is the most necessary experimental procedure.
Yes, for getting better results I think there is a step that could have been added to the procedure is to follow the international standard procedures for taking the readings by the experimenter.
