All energy flows linearly; that is, in one direction. There are several basic forms of energy, including kinetic, potential, heat, chemical, electrical, electrochemical, electromagnetic, sound and nuclear.
        
             
        
        
        
Answer:
 C. H and O 
Explanation:
Almost 99% of the human body's mass is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium and phosphorus, in that order.
Element   Symbol   % in body
Oxygen       O              65.0
Coal             C               18.5
The human body is composed of 60% water, that is, H2O.
 
        
             
        
        
        
Answer:
B) All DNA molecules will migrate up the gel toward the positive electrode.
Explanation:
Because the DNA has a negative charge - regardless the size-, all DNA molecules will migrate towards the positive electrode, at the top of the gel. This is due to the Coulomb's physic law  "force of the interaction between the charges is attractive if the charges have opposite signs". 
Instead of migrate down the gel , the DNA will do migrate up the gel (opposite direction).

If the producers were removed then there would be no beginning to the food chain and the complete ecosystem would die off. If the detrivores and decomposers were removed there would be no organic nutrients and all the dead plants would ruin the animals habitat.The ecosystem will be fill by plants and animal wastes as <span>there will be no decomposition of waste material.</span>
