Sugar molecules can be oxidized in the cell of animals . This oxidation releases energy for the animal to use. From what soured do the cells get these molecules.

through digested food

Explanation: cells get their sugar molecules from the food that is taken in by an organism. The food taken in is digested by the stomach into base materials like sugar, fatty acids and amino acids. These base materials are circulated through the blood till they get to the cells where they are needed.

The sugar is derived from the breaking down of the carbohydrate molecules in the food we eat during digestion

Explanation:

The cells get the molecules from the food we eat. The food we ingest which consists mostly of carbohydrates, fats and oils and proteins are too complex and must be broken down into smaller molecules before they can be consumed by the body cells.

The process of the breakdown of food starts from the chewing and mixing of the food with saliva after which breakdown by enzymes takes place in the intestine and in the lysosomes.

The carbohydrates are broken down into sugar, the proteins into amino acids and the fats and oils into fatty acids and glycerol.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
