What amphipathic molecules? - Answer Molecules that have both a polar and a non

In terms of water, what is a hydration shell of interaction? - Answer Water molecules will
surround the polar/charged molecules in a cage
Why is water good at dissolving charged/polar molecules? - Answer Water is dipolar, so

What is M- Molarity? - Answer Concentration mol/L
What is Brownian motion? - Answer Molecules will move randomly due to many
collisions with other molecules in a solution
What is the mean free path of molecules? - Answer time without any collisons
What is diffusion? - Answer Net flux of molecules down a concentration gradient due to
random thermal motion
Movement of molecules in a solution is - Answer Random
What is turgor pressure? - Answer Diffusion with the presence of barriers, biological
molecules are semi-permeable
What is osmolarity? - Answer The number of ions/molecules per unit volume
What is the difference between hypertonic, hypotonic and isoosmotic? - Answer
Hypertonic - Greater osmolarity outside cell
Hypotonic - Greater osmolarity inside cell
