Which of the following did not allow researchers to further explore below the ocean’s surface? a. rov’s b. alvin c. palomares d. bathysphere

The correct answer is (c) Palomares.

It is an agricultural town situated along  Mediterranean sea in Spain.This town was used for fishing and tourism. Due to an incident there was a midair collision of plane causing radioactive waste in that area. There is measurable amount of radioactive elements such as uranium, plutonium present .The infected area is approximately 10 hectares. The researchers has found no cases of health problems, or any type of contamination of food or water. But there are still some areas that remains contaminated and cannot be further touched. Pressence of such radioactive elements in the area makes it unsuitable for further research until it is completely clean.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
