In humans, life processes are controlled and regulated by the nervous and endocrine systems.
Explanation: The nervous system uses electrical signals to communicate quickly, while the endocrine system uses hormones to regulate various bodily functions, working together to maintain homeostasis.
Why other options are incorrect:
A. reproductive and endocrine systems:
While the reproductive system plays a vital role in life processes, it doesn’t have the same level of overall control as the nervous and endocrine systems.
B. respiratory and nervous systems:
The respiratory system is primarily responsible for gas exchange, not overall life process control.
C. endocrine and digestive systems:
The digestive system focuses on processing food, not the broad regulation of life processes.
