Water is called the universal solvent because other substances can dissolve in it. ]]> 2016-08-29 13:17:19 UTC https://padlet.com/ch02149/thbq5bgpof44/wish/120288965 How does water's polarity effect it's properties as a solvent? wm01145 https://padlet.com/ch02149/thbq5bgpof44/wish/120289416 Because of the different substances that dissolve into it.

What factor speeds up the rate of a chemical reaction? ch02149 https://padlet.com/ch02149/thbq5bgpof44/wish/120289680 A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.  Heat.]]> 2016-08-29 13:20:06 UTC https://padlet.com/ch02149/thbq5bgpof44/wish/120289680 What are the functions of each of the four groups of macromolecules? kh02765 https://padlet.com/ch02149/thbq5bgpof44/wish/120290696 Carbohydrates-store energy,provide structural support
Lipids-store energy, provide barriers
Proteins- transport substances, speed reactions, provide structural support, make hormones
Nucleic Acids-store and communicate genetic information
