The biological study of species offers no equivalent to such transmutation. An individual which belongs to a given species ...

Low nitrogen availability is the number one limitation to plant growth in most ecosystems. Plants in the bean family and other closely related families evolved a symbiotic relationship with bacteria ...

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So ...

For example, the atomic number of chlorine is 17. Every chlorine atom has 17 protons and 17 electrons. It has 17 positive charges and 17 negative charges, meaning that it is neutral overall. Atoms of ...

Can you imagine falling 10,000 meters (33,000 ft) from a plane, being trapped underwater for days or surviving a massive radioactive discharge? All this seems like a death sentence, but today you’re ...
