You are exercising, doing aerobics or a stair climber at your fitness center. as you increase to a high intensity of exercise, you would expect the tidal volume to increase and the frequency of respiration to increase. 
        
             
        
        
        
Answer:
The given blank can be filled with location of gene expression. 
Explanation:
A regulatory sequence refers to a section of a molecule of nucleic acid that possesses the tendency of declining or upsurging the expression of particular genes within an organism. The regulation of gene expression is an important characteristic of all living species and viruses.  
In the given case, it is essential to use the regulatory sequence of a milk gene when developing a recombinant gene as a regulatory sequence monitors the location of gene expression.  
 
        
             
        
        
        
It's basically a wave that moves back and forth at regular speed through matter. because of that it transfers energy through a medium (matter). however the movement of the wave is limited because of this but it can still move over long distances. so because of this these types of waves don't move far from their original point or Equilibrium position. in short think of throwing a pebble into water and seeing the little ripples from it, that's a mechanical wave. 
        
             
        
        
        
The random movement of molecules across a concentration gradient until the difference in concentration between two regions is near zero.
Im thinking it's active transport :) hope it helps.
