A gamete of this organism will have half that number (50), the haploid number of 25 chromosomes.
        
                    
             
        
        
        
Blood, a fluid connective tissue, provides a transport system within our body for oxygen and other important substances. Cartilage provides strong support and connection for our skeletal framework. And the function of bones is to support and protect soft tissues and organs in our body.
 
        
             
        
        
        
Answer:
The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.
 
        
             
        
        
        
Answer:
The correct answer is d. DNA polymorphism and disease gene are linked.
Explanation:
DNA polymorphism helps to study the difference in nucleotide sequence of one DNA in comparison to the standard one.
       DNA polymorphism is an important tool to analyze the disease that is caused due an alteration of gene sequence leading to genetic mutation.
Now the altered gene sequence is compared with the normally functioning gene to draw a statistical relationship between altered gene sequence that causes disease with  peviously discovered DNA polymorphism.
