Yes it is possible that a population of Norway rats carries a different genetic mutation than a population of same rats in other regions because occasionally, environmental factors of a certain area can cause the population of a region to undergo mutation .
<h3>What is the population mutation?</h3>
A mutation is defined as a change in the DNA or genetic sequence of an organism that can significantly affect or not affect the function of a specific gene in organism.
Now, we can say that it is possible that a population of Norway rats carries a different genetic mutation than a population of same rats in other regions because occasionally, environmental factors (such as exposure to harsh UV Rays) of a certain area can cause the population of a region to undergo mutation whereas the other population doesn't contain that mutation.
This environmental factor above will cause a slight change in the genetic makeup of the population of rats of Northern America. However, if the changes in genetic makeup continues to happen in North American Norway rats, a time will come when they will be genetically different from same rats in Norway or other regions by being a different specie in a phenomenon that is called speciation.

Answer:
b-108y³/x²
Step-by-step explanation:
4x^-2/(3y)^-3
negative exponent in nominator , moves to denominator and becaomes positive , and vice versa
4(3y)³/x²=4(27y³)/x²
108y³/x²
Answer:
The expression b/(a +b) does not exist when a = -b or b = -a
Step-by-step explanation:
The expression b/(a + b) does not exist if the denominator a + b = 0.
So, a = - b or b = -a.
So, the expression b/(a + b) does not exist when a = -b or b = -a.
When a = -b values, the denominator a + b = -b + b = 0. This will make the expression b/(a + b) = b/0 = ∞ which undefined or does not exist.
When b = -a values, the denominator a + b = a + (-a) = a - a = 0. This will make the expression b/(a + b) = -a/0 = -∞ which undefined or does not exist.
So the expression b/(a +b) does not exist when a = -b or b = -a
