complimentary base-pairing
Atoms and molecules are very small and the mole concept allows us to count atoms and molecules by weighing macroscopic amounts of material.
Different code words for the same concept.
hybridization is defined as the intermixing of different orbitals with different energies to form a new set of orbitals with equivalent energies and shapes
Because of the different weights of moles of different elements there can always be different amounts of moles after a chemical reaction. Ex. if i have 3 pounds of apples and 1/2 a pound are rotten then 3 days later another 1/2 pound goes rotten i still have 3 pounds in the end but i have different amounts of each type.First i had 2 1/2 good apples and 1/2 pound bad apples. but then 3 days later i have 1 pound of bad apples and 2 pounds of good apples. no neccesarlily changing the amount or atoms but the type and placment of each. the same concept can be applied to moles of elements after a chemical reaction
ammonium sulfate is a compound not an element and therefore has no atomic number. Perhaps you were thinking of molecular weight. But that is a totally different concept.

According to the biological species concept, two organisms are of different species if they do not do which of these
what is the key concept of society
No, biological species concept is NOT useful for extinct organisms at all, nor organisms that reproduce asexually; it is only useful for organisms that produce sexually.
different cost concept
The process concept is necessary in studying operating systems as each task being carried out by the processor is represented by a process. Modern computers can process many tasks simultaneously.
evolve
No. The definition of a species is often defined as the largest group of organisms capable of interbreeding and producing fertile offspring. If several are totally different they don't fit the definition.
Organisms are the same species if the have the potential, or actually interbreed one with another. Does not apply to all organisms. Bacteria being an example of this. Is not as strong a concept as once it was as it did not adequately address hybridization.
The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.
