When a stimulus is produced it signifies the production of sensation in the sensory organs. This sensation through the sensory organs (eyes, ears, nose, skin and tongue) is sent to the sensory nerve connected to these sense organs. These sensory nerves send nerve impulses through the nerve fiber to the spinal cord. From the spinal cord the nerve impulse is transferred to motor nerves.
The motor nerve then sends response to the stimulus though the same path to the region from which stimulus was received and thus the body responds through muscular activity. Such as removal of heat from the heated object if heated sensations were received.

The nucleus controls what happens within the cell
Answer:
Bilateral symmetry allows for directional motion. The coelom cushions organs allow freedom of motion.
Explanation:
Most animals are bilaterally symmetrical in nature with a line of symmetry dividing their body into two sides left and right sides along-with a “head” in top and “tail” in the bottom. Bilateral symmetry consisting an equal arrangement of symmetry about a vertical plane running from top to bottom.
The coelom is known as the main body cavity present in most animals. It is positioned inside the body to surrounds the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as mollusks, it is undifferentiated. In animals, it helps to allow freedom of motion.
