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>
Answer:
D.) both a and c
Explanation:
Past observations made early in history as well as telescopes and space probes are very important in studying our universe and galaxies.
- Space probes are increasingly gaining momentum as technological and scientific advancements are being made.
- Telescopes are used to see or picture objects that are very far away in space.
- Also, understanding the past records and historical data is essential for the study of the universe.
Microscopes are not used in galactic studies. They are only used to study the world of micro-organisms.
Answer:
1)El ciclo del agua no se inicia en un lugar específico, pero para esta explicación asumimos que comienza en los océanos. ... Corrientes ascendentes de aire llevan el vapor a las capas superiores de la atmósfera, donde la menor temperatura causa que el vapor de agua se condense y forme las nubes.
2)El sol, que dirige el ciclo del agua, calienta el agua de los océanos, la cual se evapora hacia el aire como vapor de agua. Corrientes ascendentes de aire llevan el vapor a las capas superiores de la atmósfera, donde la menor temperatura causa que el vapor de agua se condense y forme las nubes.

The statement that is true is B. <span>Dissolved minerals from rocks are deposited in the ocean. All of the other statements are not correct, they are false.</span>
They are sandwiched between two layers of heads. Recall that the heads are hydrophilic therefore they will always be on the outside and the tails are hydrophobi therefore they willl always be away from water, there fore sandwiched. I'm a bio major, hope I helped :)
