Scientists initially believed that the smallest particle of matter was the atom. then, particles smaller than the atom were discovered. what most likely contributed to the change in this theory?

The correct answer will be- the advancement in the technology

Explanation:

The atomic theory which suggested that atom is the smallest and indestructible form was proposed by the John Dalton in 1803.   Later the atomic theory was modified with the discovery of the sub-atomic particles like electrons, protons and neutrons.

This modification in the theory is the result of the advancement in the technology which provided new evidence of the atomic models which represented the distribution of the sub-atomic particles in the atom.

Thus, the advancement in technology is the correct answer.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
