<span>The kidney region where all renal corpuscles are located is the R</span>enal Cortex. It is that part of the kidney which is made up of renal lobules in the outer zone, beneath the capsule and the lobules of the renal columns
that are extensions inward between the pyramids; it contains the renal corpuscles, medullary rays, and proximal and distal convoluted <span>tubules.</span>
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
