During meiosis, chromosome pairs randomly line up along each side of the cell equator. This arrangement mixes up the chromosomal combinations, which  
 A.	helps ensure reproductive success.  
 B.	helps create and maintain genetic diversity.
 C.	helps maintain all of the previous generation's characteristics.
 D.	helps ensure an equal number of males and females in the next generation.
 
        
             
        
        
        
A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.
        
                    
             
        
        
        
The food chain that would include an aphid include:
- Plant ---> Aphid ----> Birds 
- Plant ---> Aphid ----> Spiders
- Plant ---> Aphid ----> Bat
<h3>What is a food chain?</h3>
A food chain is a chart that shows how food is transferred from producers to consumers. 
Producers are plants as they are responsible for producing food from inorganic materials using the Sun's energy. 
Consumers depend on plants and other organisms.
The food chain that would include an aphid include:
- Plant ---> Aphid ----> Birds 
- Plant ---> Aphid ----> Spiders
- Plant ---> Aphid ----> Bat
