Answer:
Water based fluid
Explanation:
The internal environment consists of water based fluid in which the cells of the body present. A fluid called interstitial fluid or tissue fluid bathes the cells and provides essential nutrients to the cell. The human skin has fatty layers that helps to maintain internal heat which is produced by the body when the outside environment is cold. When there is cold in the environment, people lives in warm shelters and wear warm clothes in order reduce the impact of cold environment.
 
        
             
        
        
        
Answer:
I would say We don't have enough evidence or Cell theory is still changing.
Explanation:

Answer: This is the definition and example of Osmosis.
Explanation: Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a region of high concentration of solvent to a less concentration of solvent, thus making the concentrations on each side of the membrane equal.
The cell membrane is also a selectively permeable membrane which allows only certain substances to pass through it. Mostly molecules move from a side where their concentration is high to a side where their concentration is less to make the concentration equal on both sides.
