The mechanism that affected the gene pool of the immigrants that entered the United states Through Ellis Island is Gene flow.
Gene flow involves the movement of genes or alleles between interbreeding populations of a particular species. In other words it is the movement of genes from one population to another population. Actually it may be an important aspect of evolution; evolution can occur as a result of genes being transferred from one population to another. Gene flow occurs when there is migration, since the loss or addition of people can easily change pool frequencies even without no other evolutionary mechanisms operating.  
        
                    
             
        
        
        
Answer:
Stage III Interpretation
Explanation:
There are three stages of perception process
•	Exposure
•	Attention
•	Interpretation
During perception, the sensory receptors are active and they receive stimulus from their surroundings.  However, the complete perception of any stimulus is interpreted  by the brain because only brain is capable of differentiating between the sensory stimulus based on the pathway followed by them. On the basis of perceived information, action potential signals are generated that are sent back to the sensory organ (perceiving the stimulus at their end) for further responses.

Answer:
Plant cells will be unable to perform glycolysis due to the inhibitor and will die.
Explanation:
Glucose is  a high energy stable compound.Therefore in order to extract the stored energy for cellular use, it must be broken down. The addition of inorganic Phosphate ions(Pi) to 6-carbon glucose compound in the presence of 2ATP  molecules is called Phosphorylation. This phosphorylation  reaction is catalyse by Hexokinase.
The 6C-glucose is spitted to  6C-Fructose phosphate, and  to 6C-fructose biphophate. The later is converted to 2molecules of 3Carbon compounds called triose phosphate.
It is during the  conversion of 2-molecules of 3C- triphosphate  to Pyruvate  that yields 2 ATPs per molecule of glucose.
Therefore if  hexokinase is inhibited ,  then the glucose phosphorylation can not occur. Hence the sequence of events as Glycolytic pathways that leads to  production of ATP during   formation of Pyruvate can not occur.
Definitely, plant cells biochemical reactions will seize, glycolytic pathways will  be inhibited,  ATPs will not be synthesized,leading to plant cells  deaths.
