Explanation:
<em>The light microscope uses visible light to produce images of objects on its slide while the electron microscope uses beams of electrons to project the image of specimens. Color is a property of photons of light, hence, the light microscope is able to produce images of specimens in their natural colors </em>
<em>The areas of the specimen on an electron microscope in which the beams of electron pass through usually appear white while other areas appear black. Hence, the electron microscopes can only produce grayscale images of specimens unless a false color is added to make the images visually appealing.</em>

Explanation:
Surfactant may be defined as the chemical that decreases the surface tension between the lungs. Pulmonary surfactant is the thin layer of fluid that increases the efficiency of gas exchange.
Type II alveolar cells of the lungs produces the surfactant. Lipida and proteins are the major constituent of the surfactant produced in the lungs. The surfactatnt is important for maintaining the integrity of alveoli.
Thus, the correct answer is option (e).
