Answer: If a solution is an acid, then it will have a pH below 7, and if the solution is a base, it will have a pH above 7 since the pH value is determined by the concentration of H+ and OH– ions.

Explanation:
the electrons are shared so its a non-polar covalent bond
 
        
             
        
        
        
Answer:
The correct option is D.
Explanation:
Adaptive radiation refers to the ability of living organisms to evolve rapidly from an ancestral forms into variety of other forms especially when the organisms move into a new environment that has abundant resources. The resources, which are present abundantly in the environment allow the living organisms to spread out in the environment and to find different habitats in the environments that favour their survival. 
In the question given above, adaptive radiation allows plants to fill different habitats (niches) that are found on land and to spread out rapidly.  
 
        
                    
             
        
        
        
Answer:
See the answer below
Explanation:
First of all, each genotype will produce games that will be aligned on both sides of the Punnet's square.
FfEe will produce FE, Fe, fE, and fe gametes. Hence, the Punnet's square showing the offspring from the dihybrid cross would be as attached in the image below.
 
        
             
        
        
        
Imagine a very tiny person is walking through the auditory tract, from the ear canal through to the auditory nerve. when that tiny person reaches the cochlea and walks along the basilar membrane, Loud frequency sounds will disturb their walk most at the base of the cochlea, and soft frequency sounds will disturb their walk most at the tip of the cochlea, the cochlea communicates with the middle ear by two holes closed by membranes: the oval window, which limits the base of the vestibular ramp and on which the abutment is attached and the round window that closes the base of the tympanic ramp and which serves as a decompression system.
