A population of deer is defined by the geographical area it inhabits. This would be the most likely answer.
When we're talking about different species we're often talking about them in terms of their geographical origins and where these deer can be found. 
        
                    
             
        
        
        
Answer:
Bacteriocins
Explanation:
Bacteriocins are the toxic proteins that are synthesized and released by the bacteria that are the part of the normal microbiota. These proteins have a molecular weight of 900 to 5800 Daltons. The bacterial species that release the bacteriocins are resistant against it. 
Secretion of bacteriocins is an adaptive feature as these toxic proteins do not allow the growth of other strains of the same species or related species. One of the examples of bacteriocins are colicins that are released by <em>Escherichia coli</em>.
 
        
             
        
        
        
The answer is A.True but they are not the only ways in which this can occur.
        
                    
             
        
        
        
Answer:D
Explanation:
Respiration is the process of taking in oxygen and release of Carbondioxide in the lungs(breathing),the absorption of the oxygen in the alveolar, into the blood stream for distribution to tissues , the combustion of the metabolites(glucose,amino acids, and fatty acids and glycerol)with the inhaled oxygen to give energy as ATPS and water vapour.
 
        
             
        
        
        
The statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy. 
<h3>What is Calvin cycle?</h3>
Calvin cycle of photosynthesis is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms. 
The Calvin cycle also called light independent or dark reaction is the second stage of the photosynthetic process. It is so called because it does not require light to occur. 
The Calvin cycle makes use of the products of the light stage (ATP and NADPH) to synthesize carbohydrates. 
However, the series of reaction is an energy consuming one, which makes use of ATP to occur. 
Therefore, the statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.
