Answer:
Symptoms and Causes of Moon Facies
Moon facies may cause the face to gradually become round, full, or puffy. The sides of your face may become so round from the buildup of fat that the ears can't be seen from the front of your face. Fat deposits in the sides of the skull can also make the face look rounder.
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
The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.
Answer:
2ml
Explanation:
you can see that the water line is directly on the 2 so its 2 ml at the top it does show the that the water dropper tool is in ml unit
