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: your answer is correct A. fact one
Answer: colostomy
Explanation:
Colostomy is a surgical procedure which is used to remove waste or feces from the body when the body is incapable of expelling out the waste. A stoma is the opening either created surgically or naturally present. It is the opening in the large intestine it allows the removal of the feces out of the body. The feces is drain through the rectum into the pouch of the collection device.
Answer:
muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
Explanation:
Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
