Fishing: primary, manufacturing, textile: secondary, insurance, banking: tertiary

Explanation:

The primary activities are agriculture, livestock, mining, fishing, forrestal exploitation (they arise based on natural resources). With respect to secondary schools, primary resources are used to transform them, for example the tomato grown to make a can of tomatoes (manufacturing industries). In the case of tertiary activities, we refer to services, which are necessary for previous activities (telecommunications, financial activity, marketing, etc.)

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
