The Permian mass extinction, occurring around 252 million years ago, was triggered by a combination of factors, including massive volcanic eruptions in the Siberian Traps that released vast amounts of greenhouse gases, leading to severe global warming. This environmental upheaval caused ocean anoxia, acidification, and altered ecosystems. Additionally, fluctuations in sea levels and possibly asteroid impacts contributed to the drastic loss of biodiversity, marking it as the most severe extinction event in Earth's history, with approximately 90-96% of marine species and 70% of terrestrial vertebrates going extinct.

What is an paleozoric era?
The Paleozoic Era is a geological era that lasted from about 541 million to 252 million years ago. It is known for the evolution and diversification of early life forms, including the rise of marine invertebrates, fish, amphibians, and reptiles. The end of the Paleozoic Era was marked by a series of extinction events, including the Permian-Triassic extinction, which wiped out about 90% of marine species.
What are some extinctions by meteors?
The most famous of course is the extinction of the Dinosaurs 65 million years ago in the Cretaceous - Tertiary period.Prior to that there was the Triassic - Jurassicextinction about 205 million years ago. Although this is a disputed impact extinction, it is still one of the theories.The most devastating was the Permian - Triassicextinction 250 million years ago in which 96% of all marine species and 70% of all land species were killed including insects. This extinction event is believed to be a series of small extinctions over time or 2 large extinctions , there are several theories from climate change to impact.The further back you go the harder it is to estimate extinctions because of the lack of fossil records but two more that are listed are.The late Devonian extinction 360-375 million years ago, again a disputed impact event, but a comet or meteor is among the favoured.And Ordovician - Silurian extinction 440-450 million years ago.
Relaying a message from a receptor protein to a molecule that performs a specific function within a cell is called?
Signaling transduction. This process involves a series of molecular events triggered by the binding of a ligand to a receptor on the cell surface, which then leads to a cascade of intracellular signaling events ultimately resulting in a specific cellular response.
What is chemical cascade?
A chemical cascade refers to a series of chemical reactions that are triggered by a specific event, leading to a chain reaction of biochemical processes. These cascades are often involved in signal transduction pathways within cells, where a molecule binding to a receptor initiates a series of reactions that ultimately produce a cellular response.
What are tsunamis triggered by?
Tsunamis are typically triggered by undersea earthquakes, landslides, volcanic eruptions, or underwater explosions that displace large amounts of water. These sudden movements generate a series of powerful waves that travel across the ocean, eventually making landfall with devastating force.
