The Correct Option is D

Solution and Explanation

The phenomenon you described, where vision is initially impaired when transitioning from darkness to light but gradually improves, is an example of Adaptation. Adaptation in the context of vision refers to the adjustment of the eyes to changes in light intensity. When you move from a dark environment to a well-lit one, your eyes need some time to adapt to the increased light, which is why you experience temporary impairment in vision before it returns to normal. So, the correct option is (B): Adaptation

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.
