I believe animals that possess homologous structures probably  evolved from the same ancestor. Homologous structures are similar because of common ancestry.  A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from  a common ancestor. 
        
             
        
        
        
The statement 'when paired with an immunosuppressant drug, saccharine (sugar) did not have immunosuppressant effects on rats' is FALSE. Saccharine is an artificial sweetener.
<h3>Immunosuppressant drugs and saccharine</h3>
Immunosuppressant drugs are a type of drug that exhibits a depressive effect o the immune system of the individual.
Immunosuppressant drugs include, for example, adalimumab, infliximab, calcineurin inhibitors, cyclosporine, etc.
Moreover, saccharin is an artificial sweetener that is 400 times as sweet as sucrose (sugar).

An enormous rift in one of Antarctica’s largest ice shelves grew
dramatically over the past month, and a chunk nearly the size of
Delaware could break away as soon as later this winter, British
scientists reported this week.
 If
this happens, it could accelerate a further breakup of the ice shelf,
essentially removing a massive cork of ice that keeps some of
Antarctica’s glaciers from flowing into the ocean. 
 
        
             
        
        
        
Answer:
Metabolic water is a water obtained from eating other organisms. 
Explanation:
Water is a by product that is gained in the process of cellular respiration. In respiration process, food molecules are broken down in the mitochondria of the cell for generating energy in the form of Adenine tri phosphate (ATP). With this ATP, water and carbondioxide is also produced. Carbondioxide is removed from the body while water is used in different processes. So desert beetle takes water from eating food substances.
