Answer:

Explanation:
autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait 
 Using the punnet square
              X       x
       x     Xx   xx
       x     Xx   xx
there is 2 X which means there is a 50% change that their child will get the trait
 
        
             
        
        
        
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
