In sound, pitch is measured in and volume is measured in
nanometers (nm); decibels (db)
decibels (db); nanometers (nm)

hertz (hz); decibels (db)

hertz (Hz); decibels (dB)

Explanation:

The Sound Measurement units are: Hertz (Hz) and Decibels (dB).

As you may know, sound travels in waves. The speed of the vibrations of these waves defines the tone of the sound. The tone is measured in Hertz, vibrations per second. The higher the number of vibrations per second the higher the sound. Hertz therefore measures the pitch of the sound. The decibel, in turn, measures the power of the sound, its energy, the stronger or weaker it is emitted. Measures the volume of the sound.

d. making up measurements to record.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
