In 1969, whittaker proposed moving the prokaryotes from the kingdom plantae to a separate kingdom due to structural and metabolic differences.
        
                    
             
        
        
        
I believe it would be B. More than a year (Since it is a slow change, and that is the longest amount of time). Hopefully this helps

Answer:
d. Ribosome
f. Cell wall
Explanation:
In humans 80s type of ribosome is present and in bacteria 70s type of ribosome is present. Human cells do not have cell wall while bacterial cells have peptidoglycan cell wall. These differences can be targeted by the potential antibacterial agents. 
For example, tetracycline antibiotic inhibits the binding of important molecules to bacterial ribosome which ultimately inhibits the protein synthesis in bacteria. Vancomycin antibiotic on other hand inhibits the cell wall formation in bacteria by inhibiting peptidoglycan synthesis. 
 
        
             
        
        
        
Answer:
1. The benefits include safer and more efficient nuclear power plants. The kind of energy that is produced is clean with no greenhouse gases and the cost of operating a nuclear power plant is inexpensive. 2.In terms of the disadvantages of uranium, it can have deleterious health effects and can lead to death because of its radioactivity. Radioactive waste is also an additional issue, if it is not disposed of at a safe place and not stored properly, it can leak radiation. Such emissions can last for centuries.
3. It produces no greenhouse gases or other waste and Tides are easily predictable. 4. High tidal power plant construction costs, Negative influence on marine
