Read the procedure. What is the purpose of the bicarbonate that is dissolved in the water?
xxTIMURxx [149]

Answer:

Through this experiment we study the process of photosynthesis.

• In the begining the leaf disks's tissue has oxygen, this allows them to float.

• Then, in the experiment we infiltrate the leaf disks with a solution that has bicarbonate, and as a result their density changes (it increases) and so the leaf disks sink.

• Once the disks are on the bottom and we direct the light to them the process of photosynthesis starts, being the bicarbonate the source of carbon for the process.

• As we know a product of the photosynthesis proces is oxygen, so when it is released into the leaf disks the overall density changes again and the disks rise.

So as we can see, in this experiment the purpose of the bicarbonate is being the source of carbon for the process of photosynthesis that occurs in the leaf disks.

How does sprinting
Vsevolod [243]

Explanation:

Much energy is demanded within a short period in a sprint as opposed to long-distance that mainly demands stamina. During sprints, therefore, the energy demands by the muscles my outpace the supply by energy because oxygen is not reaching fast enough for aerobic cellular respiration. This is why sprinting cannot be sustained for long without accumulation of lactic acid in muscles – due to glycolysis metabolisms being the main source of energy.

IN long substance however, the runner does not sprint the entire marathon but run at sustainable speeds allowing the energy demands by the muscles to be met by the more effective aerobic respiration
