Answer:
I have a similar problem for my science class, but it's worded a little differently. I would say that a possible hypothesis is if (one type of flower) is planted alongside (another type), (one type of flower) will grow the best in the soil.
Explanation:
Since there are more than two things being tested, and the comparative stuff isn't known, you kind of just have to pick one. That's the best I could think of. Hope this helps!!!
 
        
             
        
        
        
Adenine which is a purine base, always pairs with the pyrimidine Thymine in DNA and Uracil(also a pyrimidine) in RNA. The bond which is present between the two bases is a double hydrogen bond.
Guanine which is also a purine base, always pairs with the pyrimidine Cytosine, in the case of both, DNA and RNA. The bond which is present between the two bases is a triple hydrogen bond and hence, is stronger than the A-G double bond.
 
        
                    
             
        
        
        
In an energy absorbing reaction, the energy of the products is greater than the energy of the reactants. In an energy releasing reaction, the energy of the reactants is greater than the energy of the products.
