Which statement describes how geologists use data from seismographs to learn about earthquakes? PLEASE HEL

They use one reading to determine the location of an epicenter.

They map the location of an earthquake’s focus.

They often compare information from all over the world.

They measure the difference between the arrival times of surface waves.

c is the answer. hope this

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
