An ecosystem<span> is </span>balanced<span> when the natural animals and plants and non-living components are in harmony- i.e. there is nothing to disturb the </span>balance<span>. With increasing pollution, change in migratory patterns, and rise of human population, many </span>ecosystems<span> are in danger of losing that harmony.</span>
        
                    
             
        
        
        
Answer:
The correct answer is "Shine Dalgarno sequence".
Explanation:
- A consensus originally characterized throughout the mRNAs to Escherichia coli seems to be the Shine-Dalgarno chain.  
- Proteins manufactured through sequences comprising unique sequences became generated more gradually or slowly than similar proteins encoded of separate but interchangeable codons from genes, researchers observed.
 
        
             
        
        
        
Answer:
The correct answer is - through facilitated diffusion and active transport.
Explanation:
Glucose is a six-carbon sugar molecule that is directly utilized by cells to provide energy. A glucose molecule is large enough to go through a cell membrane with simple diffusion.  
Cells help glucose molecules to cross the cell membrane through facilitated diffusion and active transport. Active transport is of two types primary and secondary active transport to help the glucose molecule to cross the membrane.
Thus, the correct answer is - through facilitated diffusion and active transport.
