This change best illustrates the 3rd answer choice, Loss of Habitat. 
The plants aren't migrating, but are rather only surviving in areas where there is enough moisture to support life. The wildflowers are not adapting to grow in dryer conditions, and the species is not going extinct, as there are still some areas where the plants can get enough moisture. 
Hope this helped!
 
        
                    
             
        
        
        
Well, to answer your first question, Because there are places on Earth that are both biologically rich — and deeply threatened. For our own sake, we must work to protect them. and for your 2nd question, 3 characteristics of magnetic reversal are: field, bar magnet, and molten material. Hope this helps
        
             
        
        
        
Hello!
Genetic equilibrium is a theoretical state. It never happens in nature because it goes against evolution. 
Here are the five conditions that cause genetic equilibrium to occur: 
- No selection
- No mutation
- No migration
- Large population
- Random mating 
 
        
             
        
        
        
Answer:
Decrease the effectiveness of this process.
Explanation:
Resistance emerges is an essential part of this process because this resistance causes decrease in the effectiveness of the drugs. If this resistance is not a part of this process, the microbes get resistance from the drugs which  leads to lower the effectiveness of antimicrobial disease or infection so that's why resistance is considered as the essential part of this process of project.
