One of the examples of the action of the autonomous nervous system is :
- knee-jerk response
- pupillary reflex
- swallowing of food
- peristalsis of the intestines
The Correct Option is D
Solution and Explanation
One of the examples of the action of the autonomic nervous system is peristalsis of the intestines.
The autonomic nervous system controls involuntary processes in the body, such as the contraction of smooth muscles in the intestines to produce peristalsis. The other options, while involving reflexes and involuntary actions, are typically associated with the somatic nervous system or cranial nerves.
So, the correct option is (D): peristalsis of the intestines

- Two cities X and Y are connected by a regular bus service with a bus leaving in either direction every T min. A girl is driving scooty with a speed of 60 km/h in the direction X to Y. She notices that a bus goes past her every 30 minutes in the direction of her motion, and every 10 minutes in the opposite direction. Choose the correct option for the period T of the bus service and the speed (assumed constant) of the buses.

Neural Control and Coordination
Neural System:
Neurons are the most specialised cells in the nervous system of all animals, and they are responsible for detecting, accepting, and conveying numerous types of motives. The neurological system of low-spinal animals like Hydra is incredibly simple, consisting of a network of neurons. When the brain of an insect comprises a vast number of ganglia and neural tissues, it is optimally structured.
Coordination System:
Coordination is the process by which two or more organs work together to accomplish each other's duties. Increased muscle activity increases the supply of oxygen and the demand for energy while we exercise. When we cease exercising, our nerves, heart, lungs, and kidneys all return to normal. As a result, all of the organs' functions are properly integrated in order to conduct the exercise and supply the appropriate conditions while exercising. Similarly, in the human body, the neurological and endocrine systems work together to coordinate all of the organ activities.
