Explain the how protein contained in seeds or milk is useful for the plant sprouting from the seed or the baby mammal

Cows and other mammals produce milk to provide the food their babies need to grow. Seeds and milk contain proteins, fats, sugars and/or starch. 1. Explain how the fats, sugars and/or starch contained in seeds or milk are useful for the plant sprouting from the seed or the baby mammal

Not even understanding the question tbh

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.

the correct answer is b
