Answer:
Explanation: When you have a slow digestive system, a condition known as gastroparesis or delayed stomach emptying, these muscles don't work properly. They either contact too slowly or don't work at all and, as a result, your stomach doesn't empty properly.
Eating slowly also helps our digestion. Think of digestion as a chain reaction. As soon as we see, smell, or think about food (step 1), we start salivating to prepare for putting that food in our mouth (step 2). Saliva contains enzymes that break the food down, and moistens the mouth for easier swallowing.
The correct option is c. (20 m) .
As the formula to calculate wavelength is :
wavelength = wavespeed / frequency
The muscular system allows the body to move while the skeletal system provides a structure and form to our body. Without the muscular system we could not move and without the skeletal system we would not take any form.
Hope this helped!
