Answer:
The answer of ist question FADH2,NADH 2nd question O2  3rd question NAD+,FAD,H2O,ATP.
Explanation:
Ist answer
During electron transport chain electrons are donated by reduced coenzymes such as NADH and FADH2.
2nd answer
During electron transport chain oxygen or O2 act as terminal electron acceptor which accepts and then undergo reduction to generate H2O.
3rd answer
The final products of electron transport chain and oxidative phosphorylation are NAD+, FAD,H2O and ATP.
 
        
             
        
        
        
This would be an invasive species which is not native to the environment. It can cause harm either because it over grows (if it's a plant.) Or if it's an animal, it will reproduce and most likely take over the environment. This is because it feels the need to compete for materials, but ends either taking most or all of it. Which then ruins the food chain depending on it's diet. If it's eating a plant, then other animals that eat that plant no longer have any food. And vice versa if it's feeding on animals. Other predators, no longer have their food. 
 
        
                    
             
        
        
        
Answer:
<u><em>Tube A will turn red the fastest. </em></u>
Explanation:
- Tube A will turn red fastest because Elodea plants will take up the white light and carry out photosynthesis.
 
- In tube B, the red colour will not be generated fastly because plants do not use green light. Usually, the green light is just reflected by the plants and it is not absorbed.
 
- In tube C, no photosynthesis will be able to occur because due to the wrapped aluminium foil the plants could not receive any light for photosynthesis.
