<span>The correct answer is A. water. That's because water's chemical composition is such that it can't be decomposed and turned into a fuel. Unlike Corn, sugar cane, and wood, it can't be used to power machines. The other ones are organic and can be used as biofuel, while wood can even be used in the form of coal as coal is nothing else than wood.I hope that my answer is helpful! Let me know if you need something more :)</span>
        
                    
             
        
        
        
Hello!
Genetic equilibrium is a theoretical state. It never happens in nature because it goes against evolution. 
Here are the five conditions that cause genetic equilibrium to occur: 
- No selection
- No mutation
- No migration
- Large population
- Random mating 
 
        
             
        
        
        
Answer is [ C ] 
The reason is none other than,
→ Prokaryotes are commonly referred as most primitive organisms
They lacks membrane - bound organelles , they are unicellular organisms who does not posses a true nucleus . 
→ Eukaryotes are most likely advanced organisms , they posses a true nucleus & membrane - bound organelles as well. There are unicellular & multicellular eukaryotes 
eg : Unicellular eukaryotes like Protists

Answer:
Because of the fact that it was very Deep and heavily polluted.
Explanation:
Actual main channel depths along the river vary; with a least depth of 24' or less at a few locations at the channel edges to a maximum depth of 108' being found mid-channel at the southern approach to Hell Gate.
Due to heavy pollution, the East River is dangerous to people who fall in or attempt to swim in it, although as of mid-2007 the water was cleaner than it had been in decades.
