Answer:
The answer is letter B
Explanation:
One species will take over most or all of the zone of overlap. Because there will be a competition between the two species. One wil thrive, while the other will eventually die out due to natural selection.
It is important to remind that according to the competitive exclusion principle, no two species can occupy the same niche.
 
        
             
        
        
        
Answer:
The ability of species of living beings to overproduce offspring
Explanation:
Darwin proposed that species have the ability to produce offspring at a rate that could cause a geometric increase in the population size. This is called biotic potential. The overproduction of offspring causes intraspecific competition for the limited available resources. Darwin reasoned that the overproduction of progeny leads to a struggle for existence between the individuals of a population. He observed that the struggle for existence does not allow the population size of species to grow geometrically. 
 
        
             
        
        
        
Answer - Haploid

Answer:
Explanation:
What occurs when the stomata close and evaporation stops is that, the tension in the xylem continues to increase until the living cells of the leaf are fully hydrated. This happens according to the cohesion-tension theory of sap ascent.
This happens at night. Transpiration stops immediately when the stomata is closed. There is a cohesion between each water molecule and adhesion between the water molecules and the stem walls; water is held in the leaves ad stems when the stomata is closed this hereby increases the tension.
