Analyzing the proteins of the Racoons and lesser pandas, there will be huge similarities with minor modifications. 
These species will be very closely related. 
<h3><u>Explanation:</u></h3>
The evolutionary background of the species are mainly studied based on the similarities of the nucleotide sequences and proteins. While studying the Lesser pandas and Racoons, there was a huge similarities in then based on their structures, and on their protein composition. The nucleotide sequences also showed huge similarities which also points that they have developed from same ancestor. This is why they are very closely related with each other by means of evolution. 
 
        
             
        
        
        
Trisomy=3 chromosomes; 1 more than the required pair (2)
21=the type of chromosome 
So, here we can eliminate A and B.
Now we have C and D.
I know that when sperm cell(s) simultaneously fertilize [an] egg, a class of identical twins will form. Therefore, we can eliminate D, leaving us with merely C. Henceforth, C is your final answer.
 
        
                    
             
        
        
        
Answer:
Smooth and cardiac
Explanation:
Smooth and cardiac muscles are both involuntary.
 This means we do not consciously control them. Smooth muscles are found, for example, in the esophagus, and small intestine. The cardiac muscles are found in the heart.
The skeletal muscles are those that we control consciously, such as the muscles for moving our arms and legs.
 
        
             
        
        
        
Both cycle occur within the atmosphere but the difference that they have is at the rate with which they occur. Phosphorus cycle is one of the slowest form of matter cycles that occur on earth as compared to the carbon cycle.
