Answer:
Proteins are responsible for shaping and growth of an organism.
Explanation:
The differences in proteins lead to different in traits because it is the protein that determines the trait. The gene's sequence is like language that instructs cell to manufacture a particular protein that is necessary for the growth and development of the organism. These proteins shaped the structure of organisms so we can say that difference in traits occur due to difference in their proteins.
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light and this allows electron microscopes to produce higher-resolution images than standard light microscopes.
