Goblet cells are glandular cells, or unicellular mucus-secreting glands, present in the epithelial lining of the mucous membranes of the respiratory tract and digestive system. The mucus produced by a goblet cell is secreted in the light of the tubule in question by exocytosis and diluted with water in order to coat the epithelium exposed to harmful actions present in the digestive or respiratory tubes. [1] It has an important function of keep moist and avoid desiccation of the epithelium, particularly in the airways.

1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
Answer:
Explanation:
