Nope not a misunderstanding, just the fact that at some point the evolution of a species starts with one individual oddball. Kinda like LUCA. http://en.wikipedia.org/wiki/Last_universal_common_ancestor
At some point there was most likely one single female that is responsible for humans...
Being able to interbreed is a defineing attribute of a species. Many people missuse the word species and when one gets to the nitty gritty parts of relatedness its a useless term. At one point there was a single female that was the mother of all homo sapien subspecies and reguardless of the...
Is there such a thing as a cancer of erythrocytes? Just seems like it would be likely to happen but have never heard of such a thing. You make millions of them a day and the last step to maturation is to toss out the nucleus...sure is a lot to go wrong there.
And yes it is possible that you might have different markers than your geneitic grand father. However I would bet every single thing on this planet I can lay claim to that you dont.
Actually the only thing you have in common with the men on your fathers side is the Y chromosome. Its tiny in comparison with the other chromosomes and has very little information. All the other chromosomes are recombined (mixed between the mother and father)...
Title pretty much says it, is there an offical opinion that can be quoted somewhere to win a bet? I like unlog or Reverse log but Anti-log just sounds goofy.
The amount of energy produced by a mitochondria can be a bit quirky, the analogy of water flowing downhill is a good analogy. A trickle of water flowing downhill carrys little pressure and so would produce very little electricty, however a large river flowing downhill would create a great...
I think that the issue is that its probably a rare fungus that might only affect a weakend body. Thus only a very sick person would have the infection. A person whos immune system is loseing the battle could indicate AIDS or cancer of almost any type. But some persons who use anabolic...
I was wondering where i could find a source for the rules to find Kc from a chemical formula? My professor tonight was changeing the formula like this: H2+Br2+2HBr then showed that 2H2+2Br2=4HBr...and getting different Kc values for each. I think that this is straight out wrong but she's the...
Hoover says he isn’t worried about the process and is open to any other explanations.
“If someone can explain how it is possible to have a biological remain that has no nitrogen, or nitrogen below the detect ability limits that I have, in a time period as short as 150 years, then I would be...
The T-cells that could be triggered by APC's that incidentialy pick up self antigens and present them as forigen will be working alone. They need other signals to proliferate and remain energized. Working alone they will become anergized(they cease to function) from lack of co-stimulation and...
Positive selection (MHC Restriction) - acording to Lauren Sompayrac's lecture book titled How the Immune System Works third edition the reason for positive selection is to ensure that only antigens presented by MHC's are recognized by mature T-cells. This ensures that unpresented antigens...
All moles that change shape, color, or size, should be referred to a doctor within a reasonable time. Skin cancer is much easier and sucessfuly treated when caught early and treatment is initiated immediatly.
Well my first discovery about it was that i had delusions about the people around me. Trying to save up the 250 dollars to see someone but I am learning to pull apart the delusions. Just try to remember that its an expression of your emotions that have gotten too strong. I am still scared ill...
