<span>I think you might be asking about the 3 different osmotic conditions a cell might find itself in.  Isotonic is the normal cell environment where water moves in and out of the cell freely and equally in both directions.  It is in osmotic equilibrium so to speak.  The concentration of water and solutes is equal on both sides of the cello membrane.  In a hypotonic solution the cell will gain water and swell up -...</span>
        
             
        
        
        
Answer;
Insulin and the growth hormone
The hormones that are involved in building and maintaining healthy bone tissues are Insulin and growth hormone
Explanation;
Insulin has some anabolic properties for bone. It is uncertain whether insulin stimulates bone directly or indirectly by increasing muscle work and thus skeletal loading. 
Growth hormone is a peptide hormone secreted from the pituitary gland under the control of hypothalamus. It directly and through IGF-I stimulates osteoblast proliferation and activity, promoting bone formation. Additionally it stimulates osteoclast differentiation and activity,promoting bone resorption.
