Which phrase listed below best describes the function of the digestive system?
xz_007 [3.2K]


The best answer is C - to break down food into nutrients.

The digestive system  breaks down food  into its simplest form that cell are able to utilize  for energy.  Food is broken down into its monomer units. Proteins are broken down into amino acids, lipids are broken down into fatty acids and glycerol and carbohydrates are broken down into glucose.

Glucose is then absorbed into the blood and transported to every cell in the body. The cells take in glucose and use it as fuel and raw material  in the process of cellular respiration. From one molecule of glucose, 36 to 38 molecules of ATP ( the form of energy used by cells) are produced.

If a circle has a diameter of 16 feet, which expression gives its area in square
bagirrra123 [75]

Answer:

The options are unclear but the answer is 8^2π square feet or 64π sqfeet

Explanation:

Area of a circle is denoted by: πr^2 where r is the radius of the circle.

In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i.e. r = d/2

= 16/2 = 8 feet.

Thus, the radius = 8 feet.

Hence, Area of a circle = πr^2

= π × 8^2

= 64π or 8^2π sqfeet.
