Answer:
The measure of arc DEF is 204°
B is correct
Step-by-step explanation:
In a circle center at O.
∠DOF and ∠DEF are lie on same base but ∠DOF at center and ∠DEF on circle.
Thus, ∠DOF = 2 ∠DEF
minor ∠DOF = 2 x 78 = 156°
We need to find arc DEF.
DEF is central angle of major∠DOF
major∠DOF + minor ∠DOF = 360° (Complete angle at center)
major∠DOF + 156° = 360°
major∠DOF = 204°
major∠DOF is arc DEF.
Hence, The measure of arc DEF is 204°
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.
