So I'm building a DNA model, with the whole double helix and everything. Anyone have any suggestions as to what creative materials I could use to build it?

thanks!

Hello
I am taking a b-complex sublingual liquid. It contains 1.7mg riboflavin, 20mg niacin, 2mg b-6,1200 mcg b-12, and 30 mgs pantothenic acid in every 1 ml. dropper. I started slowly and have worked my way up to 1 full ml. per day, which isnt alot. I take it for energy, and it somehow has been helping my panic attacks too. My question is, how much is too much? I am average weight for my height. I heard that if I take to much, that I will just pee it out. Is this true? Are there any bad side effects of taking too much? Could I just slowly increase and find a happy medium?

if X,Y and Z are RV's...and are related by the eqn Y=X+Z, how do you go about finding the joint pdf of x and y?
(by the way..X,Y and Z have an exponential distribution..but i dont even mind a general soln)

Problem 1: Find an exponential function of the form f(x)=ba^x+c with y-intercept 2, horizontal asymptote y=-2, that passes through the point P(1,4). & Problem 2: If a piece of real estate purchased for $75,000 in 1998 appreciates at the rate of 6% per year, then its value t years after the purchase will be f(t)=75,000(1.06^t). According to this model, by how much will the value of this piece of property increase between the years 2005 and 2008. & Problem 3: The amount A in an account after t years of an initial principle P invested at an annual rate r compounded continuously is given by A=Pe^rt where r is expressed as a decimal. What is the amount in the account if $500 is invested for 10 years at the annual rate of 5% compounded continuously?

For about two months now, I randomly shake. To others, it looks like a bad cold chill, but for me, it is painful and embarassing. I am afraid to see a physician, because, like I said, it just looks like a cold chill.

My "shake" is violent, odd looking, random (I'm not cold), and extremely painful.

Any idea what's going on here?

When I take a shower, I take off my glasses and leave it on my sink counter. I take a shower and the mirror gets all steamy, and even a bit on the wallpaper, but none on the lights. The exhaust fan is on before, during, and after the shower. So I get done, get out, dry myself lightly with a towel, and on the face too. My glasses don't seem very steamy,but when I put it on, after about 1 second, both of the whole lenses get all foggy and stuff. Does this have to do with heat? Because, the lights don't have a lot of steam on it. What causes the steam?

For each of the following sets of atoms and ions, arrange the memebers in order of increasing size:
(a) Se(2-), Te(2-), Se
(b) Co(3+), Fe(2+), Fe(3+)
(c) Ca, Ti(4+), Sc(3+)
(d) Be(2+), Na(+), Ne.

The numbers in the ( ) represent the number of electrons added or taken away.

I just want to check if my answers are right.
(a) Se < Se(2-) < Te(2-)
(b) Fe(3+) < Co(3+) < Fe(2+)
(c) Ti(4+) < Sc(3+) < Ca
(d) Be(2+) < Na(+) < Ne
