Step two of the procedure states: "using sterile technique, place a loopful of inoculum from the m. luteus culture in the drop of nigrosin and mix." which of the procedures qualifies as sterile technique?

Ais the correct answer

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
