Examine the structure of the molecule to see if the molecule itself is polar or non-polar. If the polar atoms within the molecule even each other out by being symmetrical, then the molecule itself is considered non-polar even though the atoms within the molecule are polar. Asymmetrical molecu...
Why the basic structure of a cell membrane (bi-layer) is proteins and lipids? What are complex carbohydrates? How can you tell if a molecule is a carbohydrate? How does the phosphate part of a phospholipid affect the lipid's function?� ...
The best way to tell if something will dissolve is to look at the polarities of the solvent and the solute. If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve. If the polarities of the solvent and solute are...
Identify one element from the periodic table and explain its role in the human body (either alone or as part of a molecule). Is it something we need to survive? If so, is it found in any foods we eat? Determine the atomic number ...
Draw an arrow near each polar bond. Point the tip toward the more electronegative atom. If all the arrows point to a common center, the molecule is nonpolar. If they do not, the molecule is polar. Warning Some elements, such as fluorine, change electronegativity based on what elements they...
And then we've got nitrogen, which has basically 3 carbon groups around it. Okay? And for these 2, we're going to wind up having to draw Lewis structures to figure out what the solubility is. So what I want you guys to do is go through all of these and tell me if yo...
(Notice that if the two atoms being compared are in the same row of the periodic table, the atom farther to the right is the more electronegative atom; if the atoms being compared are in the same column, the one closer to the top of the column is the more electronegative atom.) ...

Also, it is not possible to deduce what portions, if any, of the nozzle are permeable to water. Since the swelling of the gel provides the propulsive force, the pattern of fluid flow within the nozzle is important. Therefore, we investigated several plausible permeability patterns to ascertain...
