How can you tell if a given amino acid is acidic or basic? I'm lost here. My first thought would be to look at the pKa values. There is virtually no difference in the pKa values for the carboxyl groups; all range from 1.82-2.38. The same goes for the pKa values of the amino groups; all range...

Hey guys, I'm hung up on the Gibbs Free Energy equations. I know that ?G° is the free energy change under standard conditions (1 M, 1 atm, 25ºC), and that it is characteristic for a given reaction. I think that when a reaction is occurring under conditions that are not standard the equation...

Hey guys, I'm a little confused about these types of centrifugation. Here is what I know about them: Differential centrifugation is a good way to roughly separate cellular components based on their sedimentation coefficient (which is based on mass and shape). Larger and more massive...

I think in-situ hybridization is the way to go

Hey guys, I've got a developmental question for yall. How would you experimentally compare gene expression during gastrulation in birds with that in frogs? I've been racking my brain trying to think of this, and the only way I can think of is to use a microarray, since it allows you to look at...

Thanks allday. So I guess the terminal velocity of the falling bullet (due to air resistance) is less than the initial velocity? I was thinking that its terminal velocity when falling would have to be greater than the initial velocity. So when a bullet is just fired horizontally, does air...

Hey guys, I just discovered this forum and have a question for yall. I am by no means an expert in physics. I've taken general physics I and II, but my physics knowledge stops there. Hate to do this, but I've got to ask a question pertaining to a Mythbusters episode that I just saw. They...
