Answer:
The correct answer is (A) gene A is a positive regulator of gene B.
Explanation:
When positive regulation occurs a transcription factor is required to bind at the promoter in order to enable RNA polymerase to start transcription.
RNA means ribonucleic acid and it is a long single-stranded chain of cells that processes protein.
The answer is a double carbon-carbon bond.
Anearthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault.
or
An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves.
Earthquakes are accordingly measured with a seismometer, commonly known as a seismograph.
The magnitude of an earthquake is conventionally reported using the Richter scale or a related Moment scale
An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground.
The strain becomes so great that rocks give way by breaking and sliding along fault planes.
Earthquakes may occur naturally or as a result of human activities.
Smaller earthquakes can also be caused by volcanic activity, landslides, mine blasts, and nuclear experiments.
