The Calvin cycle take place in the Stroma of the chloroplast. Calvin cycle is a set of chemical reactions that take place in the chloroplasts during photosynthesis. This cycle is light-independent since it takes place after the energy has been captured from sunlight. The process; involves four main steps; carbon fixation, reduction phase, carbohydrate formation, and regeneration phase.

The right answer is <span>A) semi-permeable membrane
<span>A semi-permeable membrane is a membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute).
</span>The tubule of a kidney consists of a semi-permeable membrane and has also specific transporters which allow absorption and reabsorption. These "tools" allows some substances like ions to be absorbed/reabsorbed (by the transporters), without any changes in the concentration of the other substances (because both the membrane and the transporters stopped them).</span>
