Because the surrounding freshwater concentration is higher than the salt concentration inside and so all the water from the vacuoles has left because of osomosis. while the marine amoeba has the surrounding salt concentration equal to the concentration inside the vacuole.
Marine amoebae live in a saltwater environment. If the vacuoles take in too much salt, it'll suck all the liquidy stuff out of the amoeba itself. Freshwater amoebae are in a freshwater environment so they don't have to worry about that.
flexible, circular moorings
Humans are not typically considered extremophiles because we are not adapted to survive in extreme environments. Extremophiles are organisms that thrive in conditions such as high temperatures, acidity, or salinity which would be lethal to most other creatures. Humans generally require more moderate conditions to survive.
We can adapt to other enviorments is one
You are not more likely to survive a collision if you are thrown from the vehicle. You need to wear a seat belt.
Harsh deserts with limited water and extreme temperatures would have been challenging for humans to survive in, as well as dense jungles with limited resources and dangerous wildlife. These environments likely pushed humans to migrate to new lands in search of more hospitable conditions for survival.

they are more likely to have individuals with an adaption
There are more than 0 humans, so yes we produce more offspring than needed to survive, however humans aren't often hunted or killed by other species so it would be difficult not do. Usually animals have many more offspring than humans do, but they are also part of the natural food chain, so that is needed to survive.
Other than our brain and the complexities that adds to our life, I don't believe we are that much more complex than other mammals.
No.
more than likely yes but it depends on how far it has fallen
The average human can survive under water for approximately 5 minutes but no more then 10.
As it will have more body fat reserves.
yes
