They haven't. Oceania is not a continent, rather it is a geographical and geopolitical region.

You mama The allele frequency does not change.
Speciation is the evolution of new species from existing species and that is what has happened here. If a species was split up due to some sort of natural disaster, each party would evolve on their own because of the isolation. They will adapt to the new environment and eventually develop a new gene pool - this is when a new species has developed.
Places can change names as a result of a political upheaval; they can also change if they are believed to have racial or ethnic connotations.
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
Yes, the concentration changes after dilution. By definition dilution means to lower the concentration.
The concentration of the salt solution does NOT change- it is saturated.
Due to the Atlantic slave trade, some West African tribes that engaged in slave raiding or trading saw an increase in power and wealth. Conversely, tribes that became targets for slave raids faced population decimation, social disruption, and economic stagnation. Overall, the slave trade contributed to significant shifts in the power dynamics among West African tribes.
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
A geographical change means one which occurs to the land and its features. This can be a result of natural events like flood or erosion which slowly eat away at the Earth's surface.
Sometimes this is possible.
Yes.
Geographical location can change the appearance of sunlight.
The question is not clear; the concentration of salt in water can be very variable.
Yes. Ph is a measurement of the concentration of the hydronium ion [H+]. If you add more water you change the concentration.
