Question: 1 / 400

Water, shampooing, and acid solutions will break which type of bonds?

Sweat glands

Blow dryer

Hydrogen bonds

Water, shampooing, and acid solutions will break the hydrogen bonds between molecules. Hydrogen bonds are weaker than covalent bonds and are responsible for the shape and stability of many biological molecules. Option A, sweat glands, is incorrect because sweat glands are responsible for releasing sweat and do not affect bonds between molecules. Option B, blow dryer, is incorrect because it uses heat to remove water from hair, but does not directly break bonds between molecules. Option D, arrector pili muscle, is incorrect because it contracts to make hair stand up, but does not break bonds between molecules.
