The cause of the change in insect characteristics occurred when a few survivors of the 1st spray became resistant to the insecticide. When they had offspring, those insect babies are born with the trait that made them resistant to insecticide. This occurs when the parents pass on the trait to their offspring. The end result is that the insecticide is less effective and more insects survive.
Answer:
The correct answer is option C. "The magnetic field of earth keeps changing because of the suns activity"
Explanation:
The magnetic field of Earth is not a steady force, and is affected by external forces such as the suns activity, particularly during strong solar/geomagnetic storms. The changes in the magnetic field of Earth explains why the auroras Are sometimes seen at northern Ohio. The auroras are created by energetic electrically charged particles accelerating along the magnetic field, if the location of the magnetic filed changes, the location of the auroras change as well.

The enzyme DNA helicase is responsible for breaking the hydrogen’s bonds between DNA strands during the unwinding of the DNA.
