Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.
hope this helps have a great night❤️❤️❤️❤️
Explanation:
Environmental changes (such as a natural disaster) may cause adaptive responses in organisms, such as the Galapagos finches. Due to the islands getting hard-hit by natural disasters, the once-same species of finch were isolated in separate islands. Each generation, through natural selection, adapted to their new environment. For example, their wingspans differed, and their beak shape adapted to their source of food in their separate environments (ranging from big beaks for seeds to narrow beaks for insects).
