Answer:

See explanation

Explanation:

The tympanic membrane or eardrum serves as a divider between the outer ear and the middle ear structures. It is gray-pink in color when healthy and consists of three very thin layers of living tissue. The eardrum is very sensitive to sound waves and vibrates back and forth as the sound waves strike it.

It is important to your business to make customers aware of your products or services.
Vanyuwa [196]

Answer: True

Explanation:

It is very important that customers are aware of the products and services your business offers because it is the most important way to ensure that they patronise you. People cannot very well purchase something from a business if they don't know that the business has that thing.

This is why companies spend a lot of money on advertising because the more they get their name out there and make customers aware of their products, the higher the chances of patronage.
