Answer:
Option (D). 
Explanation:
ATP (adenotriphosphate) molecules are considered as energy currency of the cells as molecules provide energy for various cellular functions. 
The energy is stored in ATPs in two high-energy phosphate bonds, known as phosphoanhydride bonds. This stored energy is released in during hydrolysis of ATP, which involves removal of terminal phosphate groups bound the carbon backbone. 
Thus, the correct answer is option (D). 
 
        
                    
             
        
        
        
That is the vacuole. They usually fill up with food, water, or other various wastes. 
        
             
        
        
        
Answer:
B) Krebs cycle (citric acid cycle)
Explanation:
Glycolysis breaks glucose into two pyruvate molecules. Pyruvate is decarboxylated into acetyl CoA and the reaction occurs in the matrix of mitochondria. In the mitochondrial matrix, acetyl CoA enters Kreb's cycle and is broken down into CO2 and H2O. For one molecule of acetyl CoA, two molecules of CO2 are released as a by-product. Therefore, out of three carbon atoms of pyruvate, two are released as CO2 during Kreb's cycle.
 
        
             
        
        
        
Answer: Because Watson and Crick were stealing the ideas that she made. And because if she did share it everyone would probably only acknowledged the two men and NOT Rosalind Franklin.

<span>The invention of the microscope led to the development of a much more detailed classification system. Prior to the microscope, we believed the only life was life that we could visually see with the naked eye. However, with the invention of the microscope we were able to see that more life is contained in a small droplet of water than there are people on earth. It was eye-opening!</span>
