select the word that means relate or have to do with.

one way to become a better cook is to understand the principles of science that pertain to cooking. for example, chefs and scientists know that using an emulsifier in a recipe prevents oil and water from separating. egg yolks contain emulsifiers, so adding eggs to a recipe can prevent oil droplets from clumping together when oil is mixed with water. if you want a smooth and creamy sauce, always remember the eggs.
