Answer:
More food is available for predators.
Explanation:
If biologists kept introducing hares into the environment to keep the hare population at a high and constant level so there is more availability of food for the predator and so the population of predator increases. If there is no predator for the hare so it will increase in number and eliminate all the vegetation of the environment while on the other hand, if the biologists kept only the lynx population at a high and constant level so it decreases the population of hares because lynx feeds on hare.
 
        
             
        
        
        
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels over time by not allowing water to INFILTRATE. 
Greenhouse gases (GHGs) are gaseous components that absorb the infrared radiation emitted by the earth's surface and contribute to the greenhouse effect. The increase in their concentration in the Earth's atmosphere is one of the factors causing global warming.
Concrete does not allow water from the ground surface to infiltrate to underground.
        
                    
             
        
        
        
Answer:
scientist can learn how the rat has evolved based on where they live. it also helps find what the common ancestor was and all the common traits they have, for example rats in Norway may be used to the cold. and the rats in africa need to adapt to the heat and the constant threat of them being eaten.
 
        
                    
             
        
        
        
Answer:
It causes no pollution.
Explanation:
The first concern about implementing the method used for coral regeneration is that it causes no water pollution in order to protect the other aquatic animals from the harmful effect of the method used for restoration. If the harmful effect of coral regeneration is higher and disturbing so it must be avoided in order to save other organisms but if there is no harmful effect of the method used for coral regeneration so it must be used.
 
        
             
        
        
        
Answer:
RANDOM MATING
Explanation:
random mating
The Hardy Weinberg principle of genetic equilibrium defines that gene and allelic frequencies will remain the same among the generations in an infinitely large interbreeding population. In this population the mating among the members of the population is random and no selection, migration and mutation will occur.
