there is no such thing as a non polar end, the whole molecule is either polar or nonpolar. in a polar molecule, the negative end has the purpose of being attracted and combining with the positive end of another polar molecule; if that's what you meant.

What do hydrophobic regions of molecules feel?
greasy
How do phospholipids help control the passage of materials in and out of the cell?
They have a hydrophilic and hydrophobic region. The hydrophobic regions will face inward in a phospholipid bilayer, and the hydrophilic will face outward. This creates a bilayer that only allows small, nonpolar molecules through. It makes it difficult for larger macromolecules to pass through because the hydrophobic regions will not face the water inside or outside the cell.
What is the process of molecules spreading from an area of high concentrate to low concentrate?
Diffusion describes the spread of molecules through random motion from regions of higher concentration to regions of lower concentration.
What is a reason for failure of some molecules to diffuse through a tube?
One important principal in biology and chemistry is that like dissolves like. This applies most particularly to substances that are known as either polar or nonpolar. A polar substance, like water, has an uneven distribution of charge throughout the molecule, whereas charge distribution is uniform (and often neutral) throughout a nonpolar molecule. If a membrane is polar, then polar molecules will be able to diffuse through it more easily than nonpolar ones, and vice-versa. However, in nature it is not usually that simple, and there are usually other factors involved, such as the size of the molecule trying to pass through the membrane. In biology, the membranes that are most frequently studied are what are known as lipid bilayers, and they form many important barriers around and inside of cells. Lipid bilayers contain both polar and nonpolar regions, so polarity definitely has an effect, and nonpolar molecules pass through the membrane much more easily than polar molecules do. However, although polar, water has no trouble passively diffusing across a lipid bilayer because of its small size. Gases also pass through with relative ease. In addition to this, the passage of molecules is also affected by something called gradients. If there is a large amount of a molecule on one side of the membrane and a small amount on the other, the molecules will tend to diffuse toward the side with the lower amount. Molecules always want to move down their concentration gradients, so as to make everything neutral and balanced. Hope that helped!
What are the strong forces of attraction called between the positive and negative regions of molecules called?
The strong forces of attraction between the positive and negative regions of molecules are called electrostatic forces or electrostatic interactions.
What property of detergent makes it useful to wash grease from pans?
It's because of its amphipathic nature, containing both polar and nonpolar regions.
Can polar molecules and molecules that have chargers sneak through the nonpolar middle portion of the phospholipid bilayer?
No, they are not. Micelles are formed by amphipathic molecules, that is molecules having both poplar and nonpolar regions, such as phospholipids or fatty acids. The polar region stays to the outside of the sphere as it can interact with water or some other polar solvent and the nonpolar regions are forced to the center.
Is fat polar?
Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
Are non-polar molecules hydrophilic?
No, non-polar molecules are hydrophobic because they cannot form hydrogen bonds. A good example of this would be a cell membrane. The fatty acids in the lipid bilayer are non-polar and hydrophobic, while the polar ends that face the outside and inside of the cell are hydrophilic.
Why do phospholipids orient in a bilayer when in a watery environment such as a cell?
The phospholipid molecules that make up the cell membrane naturally form a lipid bilayer. This is the most energetically-favorable conformation and is driven by the same forces that create micelles in a detergent solution.
