The invention of DNA replication through PCR!
Because of this technology, we can now classify organisms based on genetic relatedness instead of the similarity between physical traits. The more we use PCR to identify different organisms across all “kingdoms” the more the previously established family tree of life shifts into something new
The Circulatory System delivers oxygen and nutrients in the blood to the surrounding cells to maintain Homeostasis. The blood in the Circulatory System is needed throughout the body so that other systems work properly. Like for instance the Nervous System has the brain, and the brain needs blood to function.

Answer:
The weather of San Francisco gets colder with the California current.
Explanation:
The template California´s current oceanic ecosystem is one of the most productive and diverse in the world.
The California current flows from the northern latitude, running along the occidental coast of North America, forward to the South.
The cold current makes coasts colder than the east coasts. When winds blow from the sea, they bring cold air over the land because the cold California current lowers the air temperature. Even more, winds coming from the northwest originate upwellings that bring colder water from the bottom, lowering, even more, the current temperature.
Thus the temperature of California’s coastal cities, such as San Francisco, is relatively cool.
