The best answer is "a" - the overuse of antibiotic.
Emerging disease are those whose incidence has increased in the past two decades or threatens to increase in the near future.
Such diseases include :
1. Old infections emerging as a result of antimicrobial resistance due to indiscriminate or poor use or over use of antibiotics.
2. New infections resulting from evolution or change of existing organisms.
3. Previously unrecognized infections in areas undergoing ecological transformation
4. Known infections spreading to new geographical areas or population.
Antibiotic resistance has been on the rise and is now major concern.
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
In the anaphase.
Hope this helped!!!!! :)
