True or False. Complex molecules (macromolecules) are made by joining smaller molecules together using dehydration synthesis.

Answer 1

This statement is a little bit broad, but in general, yes, this is how many macromolecules are made. Macromolecules are polymers, meaning they are composed of two or more monomers. Those monomers are generally held together via covalent bonds, and often involve the loss of a water molecule (dehydration synthesis = making something new by losing a water). In other words; macromolecules are large, complex things made up of smaller molecules bonded together. A good way to hold to small things together is to form a bond between them, and often when these bonds are formed water is given off as a byproduct.
