Texas Barber Exam Practice Test

Which type of bonds are broken by sweat glands?

1. A diffuser

2. Sweat glands

3. Arrector pili muscle

4. Ring finger

The correct answer is: Sweat glands

Sweat glands are responsible for producing sweat, which is mostly made up of water, salt, and other excretory substances. The bonds that are broken are the hydrogen bonds between water molecules as sweat is secreted through the glands. This process helps to cool the body down. Diffusers, arrector pili muscles, and ring fingers do not play a role in the production of sweat or the breaking of bonds. Diffusers are used to disperse substances into the air, arrector pili muscles are responsible for causing goosebumps, and ring fingers are just a finger on the hand. Therefore, these options are incorrect.
