Does anyone know of an actual biology help forum, kind of like how this is a physics help forum. I searched for some but couldn't find anything and this place is useless for Biog. -Thanks FC Bayern Blues

I originally posted this in the homework help section but I didn't get a response so I'm going to post it here. Please don't remove it if you are a moderator because I need this answered as soon as possible and I don't think I was going to get an answer from the homework help section...

What is the meaning of "radioactive decay"? What is the proper use of the meaning of "radioactive decay"? My teacher states it is the amount of decay that has occurred and I think it is a measurement of the "rate" of decay while it is being measured. I have re-phrased this question from an...

I have a problem thinking about rotations. As we all know, it takes 360 degrees to complete a circle, 720 to do two rotations, 1080 for three full rotations, 1440 degrees for four and 1800 for five and so on. My question is, what is the amount of complete rotations a human eye can see in one...

I am doing a biology science fair. Here is my plan: I am going to ask my pharmacist for HCG containing pills, and put them into 5 different cups - one which will remain as a constant I can compare the others to. To the other four, I will add different chemicals, then test them for HCG using...

I am reading about the Calvin Cycle in Photosynthesis. My book says that the Calvin Cycle constructs a 3 carbon sugar called glyceraldehyde-3-phosphate (G3P) and then it says "You already met G3P in glycolysis. It is the three-carbon sugar formed by the splitting of glucose." So I'm thinking...

Would anyone happen to know where I could find the standard Rf values (for Chlorophyll a, Chlorophyll b, Xanthophyll, and Carotene) if varsol is the solvent? I'm trying to identify those plant pigments via Paper Chromatography, and I'd like to compare my results to the standards. The problem is...

I don't know if this is the right place to post this question, but you're a clever lot so I'm sure you'll know the answer. We are all familiar with the illusion of the wheels on a car on television appearing to spin backwards when the car is traveling forward, this being caused by a mismatch...

Do people think that eventually chemistry could explain all of biology? If not than are you suggesting there is something intrincic about biology that cannot be explained by chemistry? Why are the workings of the primitive forms of life be able to be explained by chemistry? Surely it is only...

So, if it is okay, would you mind answering this question? There has been much scientific study on the evolution of humans. Although all humans universialtlly want to be accepted, I've come to realize that this "god" that Christians are talking about is perfect. People want to be accepted, so...

Here’s my dilemma. I am enrolled in a “hybrid” class (half online/half on campus) for my biology lab starting this spring. The nice thing about it is that I only have to be on campus one night a week. The rest of the course is online. Pretty convenient for me because I have a full time job and I...

It's university application time! Here is my dilemma: On one hand, I love chemistry and biology, and am good at them, but what exactly can I do with a degree in biochem besides research and becoming a doctor? On the other hand, I'm good at math, and I know I'll find a job very easily if I take...

I believe I have found proof that infact, biology is NOT a science. My proof is as followed: 1) There are too many good looking chicks who are biology majors This is self-explanatory 2) Biology is in the news too much (evolution) People are not interested in science. People are interested...

We are learning the excretory system, and are given a thinking assignment. Okay so we are given a bunch of values for concentration of the substances in the kidney. Basically the post-glomular blood (blood after being filtered by glomerulus) has a little more protien concentration than the...

[SOLVED] biology popular science books I just finished reading Behe's Darwin's Black Box and what I really dug about the book was how it went in depth into the biological functions of things and was a really technical book(for the layman anyways). What I'm looking for now is the other side of...

There are a few threads over in homework help that are related to biology, and now that we've started the "other sciences" homework forum, we seem to get one or two every day (not a huge number yet, but hopefully it will grow). Those threads could use the attention of some of the biologists...

Hey everyone! I just started the first year of my undergraduate degree in biology this year. I chose biology because I am scientific by nature, and find the science of life most interesting. I was just wondering if any of you guys could give me any advice on which direction to go with my...

How can people be so ignorant, seriously? Bassically, he was a sub for my class because of an AP comference my teacher had to attend. I was simply studying some biology when this sub comes up to me and asks me if we learned about evolution in this class yet. I respond with a no, but we will...
