Echolocation is also called bio sonar. It is the sonar used by several kinds of animals that <span>enables them to locate and discriminate objects by projecting high-frequency sound waves and listening for echoes as the sound waves reflect off objects. </span>
Dolphins and whales make these sounds at any time and at considerable depths. Sounds vary in volume, wavelength, frequency, and pattern.
The wavelength depends on the speed of
propagation (c).wavelength=c/f The speed of sound in water is c= 1450 m/s.
So, for bottlenose delphins the wavelength is:1450m/s / 110.5 kHz
1450 m/s / 110500 Hz =0.013 m = 0.13 mm
For whales the waveleng42.5 th is:1450m/s / 42.5 kHz =
1450m/s / 42500 Hz= 0.034 m = 0.34 mm

Answer:The answer is spinal cord
Explanation:
The central nervous system consists of the brain and the spinal cord.
The brain is the most highly specialized organ, and is protected by the skull or cranium, while the spinal cord is made up of soft tissue which runs from the medulla oblongata to the tail region. It is protected by the bones of the vertebral column.
The spinal cord acts as a PATHWAY between spinal nerves and the brain.
