The bio department at my university encouraged that I "take a look at" Alberts' Molecular Biology of the Cell over this summer in preparation for a course next year. The problem with this is that I don't want to actually buy a $100+ book just for that, but the only book I have borrowing access...

Iam really interested in molecular biology and microbial genetics, did masters in microbiology and want to get into doctoral program and do serious research in my interesting field. Is it not the good reason to get into phd.

Hello to all. I work with someone who is majoring in Biology who hopes to become a medical doctor in time. I believe that at least at my school, calculus is not a part of the biology curriculum. I would like to know from those of you who know biology and calculus: 1) How much of a role...

The following represent two processes of energy production. The letters X and Y represent two products: Process 1: Glucose → Pyruvic Acid → Carbon Dioxide + X + 38 ATP - Happens with Oxygen Process 2 Glucose → Pyruvic Acid → Carbon Dioxide + Y + 2 ATP - Happens without Oxygen...

Actually, this isn't really a "Homework" question but I figured it would fit better here anyway. I'm a sophomore (in high school), taking a biology course, as the title suggests. I'm making a straight 98 and my teacher has asked me several times if I am "Bored" and suggested I brainstorm an...

hello everyone hopefully i make use of this forum "We now have an explanation of why carbohydrates is always found on the outside surface of the plasma membrane. It is because the carbohydrate was originally added by enzymes in the lumen of the ER, and membrane asymmetry is preserved when...

I love Physics. There's only a few things you need to memorize and everything else is just logical and understanding. Biology is way too much memorization. I have a Bio exam tomorrow and trying to memorize everything on the nervous system but I just can't pay attention. It is mind numbing. I...

How relevant is "biophysics" in biology? I'm making a decision between studying biochemistry at school A, or biophysics at school B. School A is bigger and more well known, especially for its life sciences, while only school B offers me the option of studying biophysics. This is undergraduate...

What possible type of engineering could I major in that would also allow me to work with marine animals?

I find chemistry extremely interesting but biology the epitome of boring. I'd rather do 10 hours of organic chemistry than 5 hours of biology. How would this relate to medical school? Is it more like chemistry (conceptual, stuff fits together like a puzzle) or biology (rote memorization)?

I've often heard this (and it concerns me b/c it's my current major) - I was wondering if there is any basis to it, and if someone can link some relevant data/statistics to support/refute this claim? Thanks :)

So I'm about to graduate this year and was wondering if I don't make it to med school what other options I have. I really like to see myself doing medical work. so what can a person with a B.S. in Biology do for living. can anyone give me ideas so that way I can start to think about them. thank you.

So for biology in particular, there are millions and millions of organisms and gene pathways that we still know next to nothing about. And for research in many of them, output is proportional to effort/money invested (in other words, you can still get things to be done without expecting costs to...

Hi I have a question about PCR markers. I have attached an image of both a pedigree and a gel showing the genotypes of a family with a history of hemophilia, an X-linked recessive disease. The question I am trying to answer is whether the PCR marker used appear to be linked to the diseased...

Hello; I am in my final year of GCSE and sooner or later I will have to pick what I want to do for AS and A2 (A-Level). For A2, I am fairly certain I will be picking Further Maths, Physics and Chemistry. For AS however, I am a little stuck. I will definitely be picking Maths/Further...

I am a junior molecular biology major. I plan to go into graduate school and currently my #1 topic of interest is using solid state NMR to determine molecular structure. I am doing research on the unrelated topic of bacteriophage genomics but do not want to change labs because I am well...

Hello, I've just started reading this book and I'm confused by the ideas he's putting forth as its going aginst what i have read from other sources. I'm keeping an open mind and reserving judgement till I've read the whole book. In chapter 1, it seems to me that he's doing away with "walls"...

A recent paper on arXiv claims a new paradigm is needed for biology. In essence the paper seems to recall mathematician David Hilbert's famous quip that physics is too important to be left to the physicist. Authors Goldenfeld and Woese claim that the existing paradigms of biology are not up the...

In a tree undergoing secondary growth, many of the tissues will split or even be shed, due to the increase in girth of the stem. Which tissues will be affected in this way? It they are lost, how will replacements be made? Could anyone please help me with this question? Thank you.

I know someone who is doing biology and chemistry 11 and soon biology and chemistry 12, but has a hard time pronouncing all the terms (learning english) Is there a website out there that helps people pronounce all the terms in biology and Chemistry, in a grade 11/12 level? Thanks!

Could I get some advice for which math to take for biology? Here's a list. https://www.physicsforums.com/showthread.php?t=432385 Thanks!

I was just curious about atoms in biology. Do organisms have the same atoms all the time? Or are they always changing? When we eat do we gain new atoms etc. Sorry if this is a dumb question. I can't find anything on it maybe because it is to easy.

1 hard(?!) Biology Question!HELP! :/ Homework Statement If life had been "intelligently" design, and if an important design principle is conservation of material and efficiency of process, we would not expect DNA replication to involve the crazy, complex, intricate, Byzantine mechanism for...

During one year, I, a mammal, traveled more than 24,000 miles but I am by far no means the king of mammals, for I have reports of mammals who've traveled more than 200,000 miles. And that's not counting our astronauts. Why are you failing to recognize our achievements as homo sapiens...

Water (H2O) and hydrogen peroxide (H2O2) both consists of hydrogen and oxygen atoms. Explain why they have different chemical and physical properties.

Hello! So in AP Biology today, we were discussing the multiple ways cells "eat", (exocytosis, phago- and pinocytosis). I asked my teacher if kinesin is used to create the "dimple" on the edge of the cell membrane during endocytosis; my teacher was clearly baffled, and ranted about the...

I'm trying to calculated the rate of reaction In this lab I took a 50 mL beaker and poured in 10 ml of cold distilled water into it, I then poured in 30 ml of original enzyme solution (I believed we used cold potato juice or something), I then took a piece of paper and placed it into a...

Why do we grow to the way we are. Are we averaged size because of average gravity. If this planet had gravity equivalent to Jupiter, would be have been shorter, like a snake, and flatter? Why can organism live in certain places like volcanoes? Wouldn't they have had to live there long enough to...

Homework Statement The maximum size to which a cell may grow is limited by the cell's ? Homework Equations NIL The Attempt at a Solution It's a multiple-choice question... so i picked nucleus. My argument is that the nucleus controls the internal functions of the cell. However...

Hi everyone, I am actually very new to biology and unable to understand some of the things. My question is that, if our heart is working because of the blood it pumps, I mean that our heart needs blood for pumping all the time and if it don't get the blood then it may stop working ! So...

On one of the X-Men movies (which sucked, by the way), the character Magneto removed an amount of iron that amounted to the size of a tennis ball from someone's body. Apparently, one of Magneto's henchmen had injected the guy with iron beforehand. I'm curious about how realistic this is...

Discrete math -- links to biology? Hey, I'm in a math and biology program in college and I've recently become more and more into the discrete side of math. I was wondering if anybody knew of any areas of research that integrate discrete mathematics and biology, as there doesn't seem to be...
