How would the number of mitochondria in an insects wing compare to the amount found in other cells in an insects body

The cells of the wings contain more mitochondria compared to the insect body

Explanation:

The cells in the wings of an insect have more mitochondria compared to the cells of the insect body. Because the wings require more energy for their movement then rest of the body.The insects primary mode of locomotion are the wings the cells of muscle help to move that's why the wings cells contain more number of mitochondria than the body.

they are known to reach a speed of 21 miles per hour

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.
