A drug that interacts directly with receptor sites to cause the same activity that a natural chemical would cause at that site is the instructors best response.  
Explanation:
Receptors are Macromolecules which involved in chemical signalling within cells. It is possible that receptors are located in the cell surface membrane. Cellular biochemical process is regulated by Activated receptor. The drugs are capable to affect to receptor who is related to the drug’s affinity and also intrinsic efficacy. 
The affinity and activity of drug is related to its chemical structure. its effect is decided by the time duration where complex persistence of drug-receptor.  
 
        
             
        
        
        
Answer:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
Explanation:
<em>(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
</em>
<em>(b) X: Decomposers return carbon to the soil and release waste. Y: Producers undergo photosynthesis.
</em>
<em>(c) X: Decomposers take in carbon dioxide. Y: Producers absorb carbon through their roots.
</em>
<em>(d)X: Producers absorb carbon through their roots. Y: Decomposers take in carbon dioxide.
</em>
<u>Box 2 (X)  would be the process through which producers fix carbon dioxide to produce their own food, the carbohydrate. T</u>he process is otherwise known as photosynthesis and can be represented by the following equation:

<u>Box 4 (Y) would be the process of decomposition.</u> Both producers and consumers eventually die and decompose in the soil. During this process, some of the carbon returns to the soil as organic matters while the process of microbial decomposition releases carbon dioxide into the atmosphere.
The correct option would be (a).

Hi there.
The nurse should explain to the client that potassium chloride is used to treat low potassium levels in the blood. 
I hope this helped you :p
        
             
        
        
        
The nonselective, passive process performed by the glomerulus that forms blood plasma without blood proteins is called filtration. 
<span>Glomerular filtration is the first step in making urine which includes the<span> separation of the liquid part of the blood (plasma) from the blood cells</span>. Glomerulus of the kidneys (a tuft of blood capillaries)<span> filters excess fluid and waste products out of the blood into the urine collecting tubules of the kidney and thus eliminates it out of the body.</span></span>
