Answer:
<u>Endocrine system, minutes to days</u>
<u>nervous system, less than one second</u>
Explanation:
Nervous system takes information through senses, processes the information and triggers reactions.
Nervous system has less reaction time because it uses <u>electrical signalling </u>(neural impulses) while Endocrine system uses<u> chemical signalling </u>(hormones).
The endocrine system responds to stimulus by secreting hormones in the blood (circulatory system) that travels to the target organ, and hence take more reaction time.
