I think it might behoove you to consider the purpose of type I pneumocytes and endothelial cells in terms of the gas exchange in your lungs..

Assuming acids, bases, and all of those are off the table...you could always do the vinegar and steel wool reaction..OR the hot ice one with sodium acetate and baking soda..

I personally find it horrendous that the President is attempting ..in a way.. to censor Fox News by (trying) denying them access to interviews. They're (sometimes...not always) asking tough questions, digging for the truth.. we should applaud that. While Fox News is 90% biased against Obama.. let's think about the other News agencies that adore Obama & fail to cover anything negative (ACORN, Czars, etc) People hate Fox News because they don't agree with them. People hate CBS because they don't agree with them. I mean, journalism has changed over the past 20 years. It's definitely not an honest line of work anymore... they don't even try their best to hide their personal biases. But the office of President should be ABOVE this "Oh you don't like me so I'm not talking to you, HAHA" garbage. The end. P.S. Quoting mostly Glenn Beck, Rush Limbaugh, and Sean Hannity in that little video is laughable. They openly point out their political views. The ONLY person you could say "don't lie, you're a damn conservative" is Bill O'Reilly. The creep claims he's a fellow Independent when he's CLEARLY in every Republican's pocket. And most of those clips, they were stating FACTUAL consequences of his current plans. Especially that /epicfail Healthcare jargon. Yes, let's just give more to the poor & steal more from the middle class. Awesome.

I think you should seek medical attention sooner rather than later! I don't think the real aim of these forums is to provide medical advice. But, aside from immediate medical attention.. I THINK you could develop a rash (not necessarily in the bite area) as well as headaches, blurry vision, the list goes on and on.

Note: This isn't graded work, it's the basics.. Use the Chain Rule to get dw/dt when, w = cos(x-y) x = t^2 y = sin t I know dw/dt = (dw/dx)(dx/dt)+(dw/dy)(dy/dt) Thus far I have, dw/dt = (-sin(x)-cos(y))(2t)+(cos(x)+sin(y))(cos(t)) Substituting in x and y.. dw/dt = (-sin(t^2)-cos(sint)(2t))+(cos(t^2)+sin(sint)(cost)) I feel like I have done something wrong (I don't have the solution to this problem)..but I know it doesn't look correct. I'm thinking that perhaps I made a mistake with the derivatives and it should be something closer to.. dw/dt = ((cos(x))(2t))+((sin(y)(cost)) dw/dt = ((cos(t^2))(2t))+((sin(sint))(cost)) But again, I'm clueless Any help is greatly appreciated Any help is appreciated

I need help starting it...I think if I understand how to start the problem I can solve it...and probably part b too. The partition function, q, can be used to determine the thermodynamic properties of a system. During the lecture for chapter 12, we have derived, as an example, the partition function of a simple two-state system. We have also used q to determine the internal energy for this system. An important aspect of thermodynamics is to know the internal energy for a system of particles that can translate (move) in free space, but that cannot vibrate or rotate (an ideal gas would be such a simple model system). a) Please derive the partition function, q, for translation in one dimension. This can be done by summing up over all the Boltzmann exponents of the energy levels determined for the one-dimensional particle in the box system: En = n2h2/(8mL2) (Eq. 9.7 in textbook) Hint: Substitute the sum in q for an integral and use the following integral: b) Based on the partition function of the particle in the box system from a), derive an equation for the internal energy of the system using the following equation: (Eq. 12.19 in textbook) Hint: To obtain the derivative dq/dT use d(T1/2)/dT = ½ T-1/2 How does your answer compare to the equation for the temperature dependence of the internal energy of an ideal gas stated in the lectures for chapter 1? Don’t hesitate to ask me if you have problems with the solution. Or not... haha

That answer is TOO simple. j/k Thanks. Yea. My brain doesn't function properly after 4pm.

The purpose of Kundt's tube is to experimentally determine the speed of sound through metal. I understand the concept.. The distance between two successive patterns (Nodes) is therefore one-half the wave length of the sound in the air. My physics teacher asked us why we measure the distance between nodes and NOT between anti-nodes.... Frankly, I have no idea. Aren't they equivalent in length?

Nevermind, I'm dumb. LoL. I think I've figured it out

Muchas Gracias I was just overlooking my results, and for some reason I have more o-bromonitrobenzene than p-bromonitrobenzene... From what I understand, the p-bromonitrobenzene SHOULD be the major product since bromine is an ortho-para director, and would want the least steric hinderance, correct? But perhaps the experimental lab reaction was not correctly completed...I'm not sure how to explain a large Ortho:para ratio. Hm. Could it be due to the fact that bromine is not a large molecule, and only larger molecules will force a the NO2 to the para position?

I performed a lab dealing with the nitration of bromobenzene.. I'm supposed to calculate the densities of 4-bromobenzene AND 2-bromobenzene. I know the mass of each, and the molecular weight, and the moles...I was wondering where to start..? Density is measured in g/mL .. I just don't see a stoichiometric relation between g/mol, mol, and mass in grams, without having a volume

I wasn't sure where to put this thread.. But anyway.. Just wondering if a pharmacology course is difficult? What all is involved in it? Like..is it something that would be fine to take as an ONLINE course?

The 'structures' were a little complex, so it was hard to spot difference >.<

I love the factorial calculators, they just say infinity. Haha, I wouldn't expect anyone to calculate such a massive number.. I just wondered if it was possible..which technically, it is. thanks

You know that always interested me, since like 7th grade.. They still don't know. Since viruses do not fit all of the criteria.. But scientists have changed several definitions over the years.. look how they just modified the definition of "planet" I just completed a biology lab where we looked at DNA from bacteriophage lambda..really neat

Well, this isn't a homework problem or anything, but we're incorporating factorials into our Calc II now..and I hate them to be honest I was just wondering what would be 4!!!! or if it's even possible to calculate. I did 3!!! which made my head hurt

Isn't that a little vague?... Look on wikipedia or something. OR for specific African countries, try cia.gov?

I'll help you for the low low price of 3.5 trillion dollars

I haven't used Powerpoint in awhile.. So specifically I can't be of much help. I suggest fiddling around with the effects/noises/animations. Make it professional but 'fun' at the same time.

Well presentation ideas...that's vague. If you aren't 100% comfortable with public speaking.. I'd suggest powerpoint. Always have a backup plan in case the Powerpoint doesn't work!

Exactly, coincidences happen all the time. Think of deja vu? Anyway look at it this way..as many times as that commercial will air (probably in the time bracket) and as many times as you will be in a sticky situation and pray. Look at the numbers. Besides, you wouldn't have thought anything of it if a Geico commercial aired instead

I'm a fairly young character, and I just ran into the same wall. My parents are apart of this theological union. Although I'm more of a Chemist myself, I overall love the sciences....but I guess science has a bad rep. Evolution for example. I've heard countless 'theologists' condemn the thought of evolution (to this very day) as lies. I discussed evolution and such with a priest at a local chapter, and he said it is merely a theory. No. I wasn't talking about the Theory of Evolution which includes the mechanisms,etc. Just Evolution as the fact. Back to others I've debated. Everytime they say, "I most definitely didn't evolve from an ape." You're right. You didn't. They don't understand that our primate relatives branched off long ago. Evolution is only one huge gap that creationists spit at. Just about everything dealing with science is viewed from skeptically. As a woman of science, you're supposed to be skeptical AND open-minded...which most of the population is not. Basically, this situation deals not only with biological science, but just about every science. I'm not sure how to alleviate the tension between theology and science...maybe it never will.. Perhaps one should start at the school level. I was fortunate that my high school had an exceptional science program, but most do not. And to me, science is the key. Or somehow scientists could try to mainstream moreso than they do. However, this is (I believe) what separates the science geeks from the English buffs and History lovers, etc. As my idol Richard P. Feynman once said, "If I could explain it to the average person, I wouldn't have been worth the Nobel Prize. " So it's possible that society will always disagree with science. Science will persevere. Science has alwas been condemned. Ask Galileo.

Unfortunately, in a scientific view...an 'organism' is considered alive when it performs the 7 functions. This is part of the reason they haven't determined viruses as 'alive'.
