I am not sure if this is in the right section so feel free to move it. Lately I have been having arguements with my Dad about glabal warming. He insists that it is not real and that evil liberals are using it as propaganda to save the environment. He keeps using the arguement that lots of scientists dont agree with global warming. Is this true? I can hardly believe that it is and i really want to be able to reinforce my facts about global warming when I am discussing it. I get the basic idea of it but could someone just explain the key points of global warming and why anyone would not agree with it? Thanks

CO2 is mainly transported in the form of H+ HCO3- in the erythrocyte . Thanks to the help of Carbonic anhydrase . However , I'm confused with the role of these enzyme . this enzyme catalyses which reaction ?? 1) CO2 + H2O -----> H2CO3 OR 2)H2CO3 ------> H+ + CO3- For our Information : The Book written by Campbell , Reece and Mitchell published by Benjamin Cummings stated no.2 The book written by Greece and Stout published by Cambridge staed no.1

What's so great about the nonspecfic immune reactions that prevents diseases? In other words, how come the bugs don't win all the time? What is it about the communication system in this part of the immune system that makes the reaction so comprehensive? Any thoughts?

Whats the average length a human shrinks during their lifetime. It terrifies me that one day - I'll be shorter than I am right now. And let me tell you. I'm a shorty. The good news is - I made it into the bottom 5th percentile. High five. No? Ok. Does someone know? Obviously, environmental factors, the way you postion yourself ...in bed .etc plays a part. I just want an average figure e.g. 1.5 inches. Atleast then its quantative so I know how much more I need to grow to stay in the bottom 5% of males. I don't want to lose my manhood (and have 60% of females taller than me). So - any help. Would be great.

(1) How might I explain the genetic basis of a disorder that occurs with equal frequency among both sexes and that doesn't follow basic patterns of Mendel inheritance?????? (2) Explain the idea of heterozygote superiority with respect to human genetic disorders. (3) In a rare form of colour blindness, a person cannot distinguish the colour blue. This abnormality, when it does occur, affects both males and females and in equal numbers. Explain this pattern of inheritance and compare it to that involved in red-green colour blindness.

If I defocus my eyes and look to the corners of my eye I can see blue and red dots in a honeycomb type of pattern. I have always been able to see them so I think it is some sort of rod and cone phenomena. Is this true ?

I am just wondering if this equipment really works correctly.

Pasteur's proof that contaminating organisms were carried in air inspired the work of Joseph Lister [1827-1912], a British surgeon. Until the mid 19th century many people who underwent surgery survived the operation but died form infection of their wounds. Lister was the first to apply antiseptic treatment for wounds. Lister was the first to apply antiseptic surgery and the prevention of infection by insisting on absolute cleanliness in the operating theatre. Pardon Me For Any Spelling Mistakes

Me and my friend were at school last week and he was talking about how atoms make up everything even cells, which led us to thinking about memory. I was wondereding if anyone on here can explain this. If the part of the brain that deals with memory is made up of cells which are made up of atoms then does that mean atoms can contain information?

Ok, so there are some creatures in the world that have spikes on them or a poisonous slime that keep predators away. How did these natural protections form in the evolutionary prospective? Wouldn't a speicies die without the protection before it could gain a trait like this? Also, lets take strawberries as an example for my next point. This fruit has no natural protection, yet it is constantly eaten by its "predators". Why has this fruit, or any other common ones, not formed protection to keep it safe?

Could anyone help me please.. I understand that virulence factors are a microbe's structures or capabilities that allow it to establish itself in a host and cause damage. However what are some examples of virulene factors in gram positive bacteria, gram negative bacteria, viruses and parasites. Can anyone help me with this please. Thanks in advance for your help...lp

there was a slice between the two eyes one third the length of the body, at which point upon completion will have formed two seperate heads

ah im not suure. is it through the marker protein?

I was curious if anyone could tell me a book to check out that has to deal with the homosexual gene debate or anything to that subject...It would be greatly app.

http://en.wikipedia.org/wiki/Human_gene_therapy I read that a virus will inject its DNA into a somatic cell in the body and then create therapeutic proteins that are required for an organism. I kept reading and learned that this injection, in situations, would lead to a permanent cure for a defect in an organism. Questions: Is the virus fought off and eventually erased from the human organism? Is the virus a permanent addition of the human creature after injection?

What is the differences between the SEED of monocot and dicot ?? I heard that Dicots do not have ALEURONE LAYER !! is it true ?? Can anyone contribute to this question ??

Does anyone know what the mosquitoes senses are and how sensative they are? I've heard of contraptions that lure mosquitoes by their attraction to CO2. Why are they attracted to CO2? Does anyone know the hearing frequency range for mosquitoes? How do the antennae of a mosquito work?

Even though this is way too impossible, I have a hard time visualizing this; what could a person with 360 degree joints (all joints) do?

I was watching CSI last night, it was a show about a girl whose parents claimed she was an indigo child. She was very bright and gifted and showed a keen intuitive ability. I did a little research on the subject and most of what I found was a little out in left field. Some sites talked about auras and psychic abilities. Don't get me wrong, I believe in the potential of the human mind, I just dont think anyone who actually has such abilities is on every wednesday night on the sci fi channel or a phone call away. What i am asking is there any scientific evidence that indigo children actually exist or is it psuedo science.

When does menstruation occur in a menstrual cycle which lasts for 22 days? 14 days after the previous one, or at the middle. Thanks

I was reading a book about the history of Genetics. It's called "Genetics: Unlocking the Secrets of Life" if anyone is interesting in renting it from their library. Anyway, I read about a scientist whose name I can't spell who won a Nobel Prize for cracking the DNA code and a second Nobel Prize for creating a synthetic gene. It wasn't an easy process. He had to painstakingly clense the reactants of any waste products after every step, but after months of hard work, when he inserted the gene into an e coli cell, the cell produced the exact protein that he hypothesised. This made me ponder: Could we take this one step further and create a synthetic life? We co…

Hello, I was wondering if there is any significance regarding the time in which alcohol has effect on the brain with refernce to the volume consumed. For example, if you were to drink a pint of beer in one go (10-60 secs) rather than say 20 mins. In short words: if you drink alcohol quickly, does it have more effect than if you drank it slowly? Sorry if this doesn't make sense?!
