Where do medical scientists get tissue samples for their research? Say if youre a neuroscientist studying brain tumors; where would you find enough tumors to study? Great questions. And the answer is that youd make a withdrawal from a biobank. A biob...
D: I guess it make sense. It's just I've heard that regular physical activity can strengthen your immune system and help prevent catching cold and other illnesses. So I figured that even if youre already sick, doing something physical may help. Y: We...
Sometimes, however, the fuel molecules dont burn up right away. They clump together to form particles called soot, which then swirl around inside the body of the flame without actually burning. As they swirl, heat from the reaction zone can make this...
Getting this slippery substance to stick to a frying pan is a bit of a trick. Teflon is broken into a fine powder and suspended in water. The pan is the n thoroughly cleaned, then roughened by sand-blasting. The Teflon is sprayed onto the pan and bak...
it's the fluorine atoms that give teflon its slipperiness, fluorine atoms are physically bigger than hydrogen atoms, it's large size makes them h* around teh central carbon chains in a much tighter formation, its tight formation works like a kind of...
Teflon is the trademark name for PTFE, a type of plastic. If you own any non stick cookware, then you probably use PTFE on a daily basis. You might not realize, as you fry your morning eggs, that PTFE is one of the most slippery materials that can be...

Heating the goo causes the coiled up proteins to unwind, or denature, exposing the water-hating red lights to water. To keep dry red lights from neighboring proteins glue together forming small nets of denatured proteins. Heat continuously applied to...
Have you ever wondered how heating an egg white turns that uncooked clear goo into an opaque gel? Well, that transparent goo is made of mostly water and proteins. Each protein is a long strand of amino acids that you can think of as a string of green...
A fire needs oxygen and some kind of fuel. This fuelwhe the r its candle wax, wood, or gasolineusually contains big molecules that have carbon atoms inside them. You can think of these molecules as little containers of energy. When theyre allowed to...
