When stem cells grown on hard, rigid surface, then they became bone cells. Researchers demonstrate in Nature materials that human mesenchymal stem cells grown on a rigid substrate for some time become biased toward differentiating into bone-cell lineage, whereas cell grown on softer surfaces are just likely to eventually follow a bone or fat cell fate.

<u>Answer:</u>
All cells have same genes, but different genes are active in different cells
<u>Explanation:</u>
        Most living organisms are made up of different kinds of cells specialize in performing various functions like nerve cells perform different functions than blood cells. But all the cells are composed of same set of genetic information. 
Since biochemical function is found out mainly by some specific enzymes, different sets of genes must be turned on and off in the various cell types to perform different functions. This is how cells differentiate for different functional capabilities.
 
        
             
        
        
        
Answer:
C
Explanation:
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.
