OK well first of all I hate biology but I like writing so you can use :: The molecular reactions of cellular respiration transform Krebs cycle into the more readily available bond energy of ATP.
        
             
        
        
        
Answer:
The primary "food"  produced by  photosynthesis is a  6-carbon sugar called glucose.

Answer:
The data from the experiment support the claim that the similar regulation of carbohydrate metabolism  by hepatocytes occurs when the cells are treated with growth hormone or insulin results from the activation of different signaling pathways
Explanation:
If we take a look on the graph, it shows increase in the phosphorylated protein when the growth hormone or insulin is applied to the cells with the passage of time. At  15 minutes , it reaches to its highest level but after 15 minutes of addition of growth hormone and insulin, the level of phosphorylated protein decrease when the time exceeds from 15 minutes to 240 minutes. So it is concluded that growth hormones or insulin increase the level of phosphorylated protein.
 
        
             
        
        
        
Answer:
Explanation:
Fundamental niche is the entire set of conditions under which an animal (population, species) can survive and reproduce itself. Realized niche is the set of conditions actually used by given animal (pop, species), after interactions with other species (predation and especially competition) have been taken into account
