B) the model does not show that cells can contain smaller structures inside.
This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.
Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.
The main purpose of hemoglobin is the transport of OXYGEN and CARBON DIOXIDE
The pyloric sphincter is compose of smooth muscle and is located between the pylorus in the stomach and duodenum of the small intestine. In digestion, it serves as a valve controlling the flow of food thus it prevents the contents of small intestine backing up into the stomach.
The Centrosome is the organelle responsible for organizing the cell into two parts in preparation for cell division. It develops the spindle fibers used in cell division.
The solution is B.
