The U. S. government protects fish, a common resource, by A. heavily taxing competing industries. B. subsidizing the fishing industry. C. selling fishing licenses and regulating fish lengths. D. None of the above is correct.

The U.S. government protects fish, a common resource, by selling fishing licenses and regulating fish lengths

Explanation:

When there is regulation about a particular goods, it reduces the rate the availability of such goods is abused, US government could actually protect fish through licensing and regulation of the type to be sold including there length which ensures the protection of the juvenile.

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.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
