Strike441 [17]
Hi there!

This would be an example of an energy pyramid! In an energy pyramid, the next trophic level gets only 10% of the energy from the level below it. In this example, lets say that there is 100 energy in the eggs. Then, 10% of that goes to the snake, so the snake gets 10. Lastly, the hawk eats the snake, so the hawk gets 1. The answer is 1%, option A.

Hope this helps!! :)

Cells are starved of energy when _ is unable to enter
defon

Answer:

Here is the complete statement: Cells are starved of energy when GLUCOSE is unable to enter.

Explanation:

Glucose, which is a monosacharide is the primary source of energy for all the cells in the body of humans. Glucose is the end product that is typically obtained from the digestion of carbohydrate. After digestion, the glucose is absorbed by the small intestine and is transported into the blood. Glucose needs the enzyme insulin in order to enter the body cells. When the glucose enter the cells, the cells use it to produce energy in the form of ATP. Without energy cells can not survive.

Without the help of insulin, glucose will not be able to enter the cells and the cells will starve and start to look for other meaning of biological fuel. This may include breaking down the protein in the body to convert it to glucose for energy.

The disease condition in which glucose that is present in the blood is not able to enter the cells due to non functional insulin is called diabetes mellitus.
