What determines osmosis from one fluid compartment to another?

Option B) the relative concentration of solutes in each compartment

Explanation:

Options for the question

A) the temperature difference between compartments

B) the relative concentration of solutes in each compartment

C) the relative volume in each compartment

D) the relative size of each compartment

Solution -

Osmosis is a physical process in which two solutions are kept in two different chamber separated by selectively permeable membrane such that molecule of one solution starts flowing towards the molecule of other solution.  

This net movement of molecules from one solution to other solution depend on the solute concentration of the two solutions.  

The solute particles tends to move from chamber having solution with higher solute concentration towards the chamber having solution with lower solute concentration

Option B is the correct answer

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
