Answer:
Transcription of gene A is not affected
Explanation:
A transcriptional repressor is a DNA/RNA-binding protein that acts to suppress gene expression and/or protein synthesis by binding to target sequences. Moreover, a silencer is a DNA region that binds to particular transcriptional repressors in order to suppress gene expression. In this case, the transcriptional repressor is activated by binding to an effector molecule X (e.g., another protein). In consequence, and since the activated repressor-X complex is not more able to bind the silencer of gene A, it is expected that such complex will not be able to affect transcription of the target gene.
 
        
             
        
        
        
Answer:
A group of similar cells that serve the same purpose.
Explanation:
a group of the same cells makes a tissue.
 
        
                    
             
        
        
        
The answer would NOT be B for this question.
 Knowing myself the answer would be A because nuclear energy would be an alternate source of energy unlike natural gas.
 
        
                    
             
        
        
        
Answer:
community
Explanation:
Community refers to a group of populations of different species that live together in a defined habitat. These species exhibit interdependence for one or other resources. It is a level of the ecological organization just above the population and consists of hundreds of different types of organisms of various species. 
Butterflies and flowering plants belong to different species. Butterflies are dependent on these plants for food. Therefore, these two together represent two populations of different species living together in habitat and are an ecological community.
