If we subtract the atomic number from the weight, we get the number of neutrons in the particle. This is because protons and neutrons each have a weight of 1, while electrons are 0. And since the atomic number is also the number of protons in the atom, subtracting it from total weight gives us the number iif neutrons.

Answer: Natural selection is the driving force to explain the mechanisms of evolution.
Explanation:
◼In a given population Organisms usually produce more offspring than what the environment can support.
◼ VARIATION, is driving force for the manifestation of sustainable inheritable characteristics from parents in a given population.
◼ Organisms, who acquired certain characteristics from variation; tend to survive than others, and therefore pass these inheritable characteristics to their offspring.
◼There is competition for the available resources among the offspring which leads to a stable population in size after a period of time.
◼Darwin deducted that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).Therefore natural selection takes place, and the organisms with best variation will have selective advantage above others. Consequently they have higher survival rates compare to others in the population.
This is survival of the fittest by natural selection
, this is the second conclusion of Darwin theory.
d. most single-celled eukaryotes. These organisms have only one cell, but just like other eukaryotes, contain a well-developed nucleus. Single-celled eukaryotes fall under fungi and protista.
