The most important factor which determines whether the living things can survive in a body of water s its salinity. The salinity level of the water is the factor at play in deciding which of the living organisms live inside the water. The salinity of the organisms has to be similar to the salinity level of the water in order for them to survive, otherwise, they will be dehydrated as a result of osmosis.
Hence, the answer is 'salinity'.
The correct option is this: CELL 2 WILL THE ONE THAT WILL BE ABLE TO ELIMINATE WASTES MOST EFFICIENTLY. This is because it has the highest surface area to volume ratio which facilitates the exchange of materials between a cell and its environment.
The rate of diffusion of materials into and out of the cell depends on the surface area to volume ratio of the cell. The higher this ratio, the higher the rate of diffusion.
