Question

In humans, the life processes are control and regulated by

• A. Reproductive and endocrine systems
• B. Respiratory and nervous systems
• C. Endocrine and digestive systems
• D. Nervous and endocrine systems

Answer 1

The correct option is D

Nervous and endocrine systems

The correct option is D.

Explanation for correct option-

1. Control and coordination involve generating a response against a stimulus through proper regulation and synchronization of the body parts.
2. In animals (including humans), the control and coordination centre comprises the nervous system, the sense organs and the endocrine system.

Explanation for incorrect options-

Option A:

1. The reproductive system is concerned with facilitating reproduction in living beings, a life process.
2. The endocrine system is one part of the control and coordination centre in animals.
3. The reproductive and endocrine systems together do not comprise the control and coordination centre in humans.

Option B:

1. The respiratory system is responsible for supplying oxygen to the body and generating energy in the form of ATP.
2. The nervous system is one of the parts of the control and coordination centre in animals.
3. The respiratory and nervous systems together do not comprise the control and coordination centre in humans.

Option C:

1. The digestive system is responsible for breaking down food particles to produce nutrients that are further broken down for energy generation.
2. The endocrine system is a part of the control and coordination centre in animals (including humans).
3. The digestive and endocrine systems together do not comprise the control and coordination centre in humans.

Final Answer: In humans, the life processes are controlled and regulated by the nervous and endocrine systems.
