General paradigms of species extinction risk are urgently needed as global habitat loss and rapid climate change threaten Earth with what could be its sixth mass extinction. Using the stony coral Lophelia pertusa as a model organism with the potential for wide larval dispersal, we investigated how the global ocean conveyor drove an unprecedented post-glacial range expansion in Earth׳s largest biome, the deep sea. We compiled a unique ocean-scale dataset of published radiocarbon and uranium-series dates of fossil corals, the sedimentary protactinium–thorium record of Atlantic meridional overturning circulation (AMOC) strength, authigenic neodymium and lead isotopic ratios of circulation pathways, and coral biogeography, and integrated new Bayesian estimates of historic gene flow. Our compilation shows how the export of Southern Ocean and Mediterranean waters after the Younger Dryas 11.6 kyr ago simultaneously triggered two dispersal events in the western and eastern Atlantic respectively. Each pathway injected larvae from refugia into ocean currents powered by a re-invigorated AMOC that led to the fastest postglacial range expansion ever recorded, covering 7500 <span>km in under 400 years. In addition to its role in modulating global climate, our study illuminates how the ocean conveyor creates broad geographic ranges that lower extinction risk in the deep sea.</span>

Adaptation

Adaption is the biological process by nature of fitting an organism to its environment.

The finches on the different islands share the same ancestral population that migrated to the Galapagos Islands. However, due to the different environmental conditions on the different islands, the population adapted variably to enable them survive on their respective islands.

Explanation:

Adaptation occurs by natural selection pressures on a population. The individuals with desired traits are more likely to reach maturity and pass down their genes the next generation (due to competition for resources). Therefore, over generation, there will be more and more individuals with these desired traits and fewer and fewer with undesirable traits. The population, therefore, evolves with time. In the case of the Finches this is called divergent evolution/radiation.

Alla [95]

Answer:

Buffy coat.

Explanation:

Between the plasma, and red blood cells the platelets, and white blood cells form a thin white layer which is known as Buffy coat following density gradient centrifugation of the blood.

Centrifugation is the process where the distinguish between cell fragments, and cell from the liquid intracellular matrix occurs. Centrifugation is a technique which separates the particles according to their size, density, viscosity and shape with the help of centrifugal force.
