AI Thread Summary

H+ ions increase ocean acidity by reacting with carbonate ions (CO3^2-) in calcium carbonate (CaCO3), leading to the dissolution of CaCO3. The presence of H+ ions shifts the equilibrium of carbonic acid dissociation, promoting the formation of bicarbonate (HCO3^-) and reducing available carbonate ions. This process negatively impacts marine organisms that rely on carbonate for shell and skeleton formation. The reaction equations for carbonic acid dissociation include the formation of carbonic acid (H2CO3) from CO2 and water, followed by its dissociation into bicarbonate and hydrogen ions. Understanding these reactions is crucial for assessing the impact of ocean acidification on marine ecosystems.

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
