Does the phospholipid bilayer reverse when it comes into contact with the chloroform solution? Normally in an aqueous solution like water, heads would be out and tails in, (polar heads, apolar tails) but in chloroform which is a non-polar substance, would the bilayer reverse and have tails out...

Check out the units. Wavelength = meters Speed of light = meters DIVIDED by seconds Frequency = 1 DIVIDED by seconds write these down on a piece of paper and try to figure it out from there... what are you trying to get?

Has anyone heard of the IBB? I think I might participate in it seriously, and if so, I'm going to need some assistance on what to study, how to go about it, and maybe even a mentor that I could talk to ;P Basically this is a contest about neurology, and all stuff relating to the brain. A...

Not really cell regeneration but more along the lines of cell preservation... As you grow older your cells actually weaken, they don't produce as fast, they aren't as receptive, they metaphorically fade out - which is a cause for diseases directly related to age such as cancer and Alzheimers.

Maybe a strange question but is there ANYTHING in-between the phospholipid bilayer itself? as in between the space where the two heads are... where all the tails are crammed together and the proteins are integrated into the cell membrane. cholestrol? or is all that space inbetween the bilayer...

This is not true... the molecular mass that relates to London forces (which is a relatively weak intermolecular force) does not have such an impact in this case. Think about the electronegativity difference between H and Br. Also, think about whether or not there is hydrogen bonding (a...

If anyone is able to help me with this question regarding introductory Data Management, I would be grateful. Find the sum of all the five digit numbers that can be formed using the digits 1,2,3,4, and 5 without repeating any digit. Thank you! Artermis

My bet's on the gecko. :P

Moonbear... you are so evil.

It also might help to reveal your age...

You are in Grade 12 Calculus (and Analysis)? The rest of my post will assume that. I suggest making friends with some people in your class that are good at math and also talking to the teacher to look for some assistance. Ditch your pride and start asking questions in class as well and ignore...

Taken from http://www.chemguide.co.uk/atoms/bonding/hbond.html : "In methoxymethane, the lone pairs on the oxygen are still there, but the hydrogens aren't sufficiently + for hydrogen bonds to form. Except in some rather unusual cases, the hydrogen atom has to be attached directly to...

awesome. Oh, Be A Fine Girl, Kiss Me Right Now or Soon Charles Cockell :P

It's used to remember the order from brightest (hottest) stars to the dimmest (coldest stars). I remember that it starts with Oh,... then in the middle it maybe be: " Be It A Fine..." Boy/Girl, Kiss Me! So the order is like O ... B G K M It's driving me nuts; please help me!
