Copper deficiency is a rare disease that leads to hematological disorders. It is an essential trace element. It is an essential part of some enzymes (c0-factor) that plays role in cellular respiration. Copper is also an anti-oxidant that scavenges free radicals. In case of cellular respiration copper is responsible for electron transfer of oxygen.  
        
             
        
        
        
 Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.

What is photosynthesis?</h3>
Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.
In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.
The following is a balanced chemical reaction for photosynthesis:
    
                                      Sunlight
6CO2    +              6H2O  —---------> C6H12O6 +     6O2.
(carbon                (water)                  (glucose)       (oxygen)  
dioxide)

Answer: The Golgi apparatus.
Explanation: I believe it is the Golgi apparatus as the Rough ER and Smooth ER create proteins and sort them in to piles before sending to the Golgi apparatus to deliver.
The Smooth ER and Rough ER are like the suppliers while the Golgi apparatus is like the transporter. 
Remember: Proteins have many functions and are needed severely to perform those actions that without the Golgi apparatus, those proteins wouldn’t be able to be transported.
 
        
             
        
        
        
Answer:
D
Explanation:
Bohr determined that there are discrete (unique, different from one another) energy levels in the atom and that electrons will orbit the nucleus within these energy levels, known as orbitals.
