Diffusion and osmosis are examples of what transport because they use what energy to move molecules

Pardon me because my answer might not fill in your blanks correctly, diffusion and osmosis are spontaneous movements of particles, and do not require any energy 

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
