There, the food is churned into a liquid mixture called chyme that moves into the small intestine where peristalsis continues. Stretching out a piece of intestine will make it easier to see the wave-like motion

The geosphere represents all of the rocks, minerals and ground that are found on and in Earth. It includes the ocean floor, all of the rocks on the surface, and all of the sand in the deserts.
Biosphere on the other hand is composed of all the living organisms on Earth (including human).
 
        
                    
             
        
        
        
You should use the same amount of beads for both chromosomes because they need to match in size. 
I am assuming you are making a pair of homologous chromosomes out of pop beads, and they should have the same size because they code the same information, the only difference between them is that one comes from the mother and ther other from the father. (Homologous chromossomes have the same genes in the same loci).
