every cell has work to do but different cells may have different jobs in multicellular organisms, cell with the same type of job often work together. These group of specialized cell from tissue in turn, tissue often group together to form larger units called organs the heart is an organ; so is the stomach.
 
        
             
        
        
        
Hi,
I browsed through internet about the enzymes and found that there is an exercise with a list of three enzymes and probably you want to know, which are the enzymes that came from the stomach of Mondoni-a little mammal organism.
Please see the graphs i found, they contain the pH and temperature of the enzymes. So, we need to find the enzymes of Mondoni on the basis of these pH and temperature values.
The enzymes that came from Mondoni's stomach are A and B. These enzymes performed well at low pH and this indicates that they are probably digestive enzymes and have acidic nature.
Moreover, enzyme A and B perform better in low temperature and performed worst in extreme temperature like 80 degree Celsius. Their temperature range also matches with the temperature of mammals, therefore enzyme A and B came from Mandoni.
Hope it helps! :)
 
        
             
        
        
        
Answer:
The alveolar walls and capillary walls share a membrane. That's how close they're getting. This allows oxygen and carbon dioxide to readily pass from the respiratory system to the circulation. Oxygen molecules bind to red blood cells as they return to the heart.
