Answer:
a.	a portion of the population becomes isolated from the remainder of the population and experiences different selective pressures
Explanation:
This is an example of allopatric speciation Allopatric speciation is a form of speciation (formation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations  reach a high level  of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
For example, Galapagos finches are isolated from others by the ocean (geographic isolation).  Because of the isolation, the finches don’t breed with one another. So, they developed unique characteristics and became endemic.
 
        
             
        
        
        
Answer:
The correct answer is cell organelles. 
Explanation:
A unique membrane-bound composition, which is found inside the eukaryotic cell's cytoplasm, that is, in plants and animal cells is termed as cell organelle. Some of the examples of cell organelles found within the cells of eukaryotes are endoplasmic reticulum, Golgi complex, mitochondria, chloroplast, etc.  
All these organelles play an essential function for the proper functioning of the cell, like chloroplasts found in plants play an essential role in the process of photosynthesis, and mitochondria both in plants and animals are regarded as the powerhouse of the cell.  
 
        
                    
             
        
        
        
If the statement is asking whether it is true or false, the
answer is true because eating breakfast and skipping snack before lunch is
considered to be a type of behavior modification in which a behavior
modification focuses to the behavior change is being limited because of the
observation seen or employed.

They both eat, predators eat prey, and prey eat plants.
