Answer:
1) 5 kingdom system of classification is a type of classification in which all the living organisms are classified into 5 kingdoms i. e. protista, monera, fungi, plantae and animalia. 
2) Plants are autotrophic organisms while animals are heterotrophic. Plants have cell wall while cell wall is absent in animal. Plants are fixed while animals move from place to place. 
3) Both plants and animals are made of cell. Both plants and animals are multicellular organisms. Both plants and animals reproduce. 
4) Plants make their own food while fungi are unable to make their own food. Plant cell wall is made of cellulose while fungi cell wall is made of chitin. 
 
        
             
        
        
        
The answer is descent with modification. 
Descent with modification practically means that a species have changed appearance wise over long periods of time to adapt to their environments better.
        
                    
             
        
        
        
If you compare the original DNA with the mutated DNA, the first C got “substituted” by an A after the mutation.
So the answer is (C) substitution.
        
                    
             
        
        
        
Single Recognition Particle (SRP) RNA is necessary for the targeting of proteins to the prokaryotic plasma membrane or to the eukaryotic endoplasmic reticulum membrane. Its job is to bind to the signal peptide of the membrane or secretory proteins coming from the ribosome at which time it forms a ribosome-nascent chain (RNC)-SRP complex.
 SRP plays an important role in understsnding bacterial physiology, emphasizing the importance of proper membrane protein biogenesis, and demonstrates the ability of time-resolved quantitative proteomic analysis to provide new biological insights.
