Answer:
The rule of magnetism illustrated is the field lines are more concentrated at the poles and also about the direction of magnetic field.
Explanation:
- Every magnet has two pole, north pole and south pole. The like poles repel each other and unlike poles attract each other.
- The direction of magnetic field is from north to south that can be seen by the iron filling experiment.
- When the iron fillings are kept near the bar magnet, we observe that most of the fillings are attached to either poles.
- It is due to the fact that the concentration of magnetic field is highest at the poles.
Answer:
The Correct answer is “No, without lactose, the repressor protein will continuously avoid record”
Explanation:
The reason behind this is because the E. coli of lac operon comprises genetic factor that elaborate in lactose digestion. It is articulated when the lactose is exist and the glucose is absent. Therefore, it is upon the absence of lactose, thus the lac repressor quandaries strongly to the worker and averts the record by RNA polymerase.
