Saline solutions have the same or close to the same amount of salt as our blood does, so we get the amount of salt needed for our bodies. During blood loss, you lose the salt you need, so they're basically adding it back in with the saline solution, making your electrolyte balance go back to normal level. It also gives us the right amount of water to keep us hydrated.
Photosynthesis, because the equation is using light energy and producing oxygen, like a plant, which use photosynthesis to make food.
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.
