Answer: B. Wave A is louder than Wave B.
Explanation: The loudness of sound is measured in unit called decibels (dB).
A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.
Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.
Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.
The correct answer is Integumentary system.
The integumentary system includes skin and all its appendages (hair, scales, feathers, hooves, and nails) with the function to protect the body. It protects body from damage, from loss of water, from abrasion from outside and even protects the deeper tissues. On the other hand, integumentary system excretes wastes, regulates temperature, provides synthesis of vitamin D and many other things.
