discovery that humans have approximately 20,000 genes

creation of PCR-based tests for many genetic diseases

Explanation:

Human genome project was an interanational project to study human's DNA; more specifically the base pairs (A, T, G, C) for protein coding genes. It was started in 1990 and completed in 2003. The direct outcome of the project was the discovery of at least 20,000 genes that encodes for proteins. Further, the base information helped establish polymerase chain reaction (PCR) based diagnostic tests for identification of genetic diseases. These genetic diseases are often studied via single nucleotide polymorphism (SNPs).

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.

explanation:

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
