During osmosis, which of the following will occur if the left side of a selectively permeable membrane has a higher solute conce
storchak [24]

Explanation:

Water molecules from the less conentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.

In diffusion small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. Similarly, during osmosis the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.

Many of the organisms in the ocean are nutrient-limited. if you wanted to investigate this phenomenon, one reasonable approach w
Mamont248 [21]
None of the provided options are reasonable. <span>comparing nutrient concentrations between the photic zone and the benthic zone can not tell you whether differences in concentrations between the photic and benthic zone are due to uptake by phytoplankton or because nutrients are sinking to the sea bottom and ocean stratification is preventing mixing.  The approach of c</span><span>ontrasting nutrient uptake by autotrophs at different locations under different temperatures would not provide useful information on limiting nutrients. but rather uptake rates at different temperatures.  It is likely that e</span>xperimentally enriching some areas of the ocean and compare their productivity to that of untreated areas can provide an indication of limiting nutrients, but this is not advisable, as it would have to be done on a large scale, and one cannot be sure of the ecological consequences. Also, because it would not be a controlled experiment, other factors could create 'noise' in the data. The last option, <span>observe antarctic ocean productivity from year to year to see if it changes, also does not help, as there is no correlation between nutrient concentrations using this approach. The best approaches would be either the last approach, but with the additional monitoring of nutrient concentrations, or under a controlled laboratory experiment.</span>
