Answer:
Removing just one species can be a disturbance
Explanation:
Ecosystem consists of a diverse organism and there is a complex interactions between those organisms.For instance if plant species keeps on growing and the animals which exists by consuming these plants suppose if such animal population grows then there will be reduction in the plant population Ecosystem contains many such dependencies.Therefore removing just one species can cause a disturbance to the biodiversity of an ecosystem.
 
        
             
        
        
        
1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in  five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.
2. During DNA elongation, helicase enzyme separates the double stranded DNA  into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.
        
             
        
        
        
Answer:
Introduction Purpose: Explore the interdependence of organisms by  
performing an experiment with lima bean plants and earthworms. Question: How can the presence of one species benefit another in  
the same ecosystem?  
Hypothesis: If plants grow in soil containing worms, then the  
plant growth will be greater, because worms help decompose organic matter and distribute it through the soil in a form that plants can use.
