→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.
The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.
And how would that ↑ explain Evolution?
Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.
→ As mentioned before, not all characteristics are enough to surive, and hopefully the image pasted below will help you.

An estuary is partly enclosed coastal body of water with one or more rivers flowing through it, and with a free connection to the open sea. it would be more of a collection. hope this help have a great day.
I'm a little confused by this question. Hypertonic just means that something has more of something than another thing. For example, if you place a cell in a solution, and 2% of the cell is made out of something while the solution is made out of 40% of the same thing, the solution would be hypertonic to the cell. Sorry if that explanation doesn't make sense, I tried my best lol.
Although I'd assume the answer is passive transport as anything that is hypertonic to something else will diffuse down its gradient in an attempt to reach a balance.
Answer: different species
