atoms of the same element that have different numbers of neutrons and thus different atomic masses; some are unstable, or radioactive electrons negatively charged subatomic particles that orbit the nucleus of an atom in a region of space called the "electron cloud" ...
Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. Atoms of same element can combine in more than one ratio to form two or more compounds. ...

PART A - Analyzing the data Tables like the one shown here are useful for organizing sets of data representing a common set of values (in this case, percentages of A, G, C, and T) for a number of different samples (in this case, species). Does the distribution of bases in sea urch...
What elements are proteins made of? Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are...
