Answer:
C is the correct option. Storage of carbohydrates is not a function of the skeletal system.
Explanation:
Option A is correct because the skeletal system has parts like the red bone marrow in which red blood cells and white blood cells are produced.
Option B is correct because the bones store minerals like calcium and phosphorus.
Option D is correct because the major function of the skeletal system is to provide support and protect the vital organs of the body.
The skeletal system is not involved in storing carbohydrates. Hence, all statements are true except for statement C.
The process of osmosis explains what happened to the cells.
Osmosis is where water molecules will flow from a region of higher water potential to a region of lower water potential, through a partially permeable membrane. Red blood cell is a human cell and have a partially permeable membrane. At the same time, pure water has the highest water potential among all substances, and of course higher than the cytoplasm of the red blood cell, therefore, water molecules will flow from the water to the red blood cell.
So much water has flown to the red blood cells that the cell membrane cannot hold all and eventually the cell bursts. Therefore, the process of osmosis explains this result.
Answer:
Mammals evolved from a group of reptiles called the synapsids. These reptiles arose during the Pennsylvanian Period (310 to 275 million years ago). A branch of the synapsids called the therapsids appeared by the middle of the Permian Period (275 to 225 million years ago)
