• A. Organism, Organ, Tissue, Cell, Organ System

• B. Cell, Tissue, Organ, Organ System, Organism

• C. Organism, Organ System, Organ, Tissue, Cell

• D. Organ, Organism, Cell, Tissue, Organ System

An organ's structure is important for its function. The larger the surface area of a structure

• the less cells it contains.

• the more the human body needs it.

• the more material it can absorb.

• the less it functions.

Sondra reads the following paragraph in a science book: “The small intestine is the place in the body where certain nutrients are absorbed from the food that is being digested. The lining of the small intestine is covered with many tiny folds. These folds allow more of the inside surface of the small intestine to be in contact with the food that is being digested and absorbed.” Which argument about the folds in the small intestine is supported by the evidence in this paragraph?

• A. They have an important role in the digestive system.

• B. They function by pushing food through the digestive system.

• C. They exist because the small intestine is part of the digestive system.

• D. They determine what nutrients will be absorbed in the digestive system.

• The function of a cell determines the job of the cell

• The job of the cell is the same no matter the structure

• The structure of the cells are different depending on their function.

• The structure of the cell is related to its shape
