2. Write a detailed conclusion based on your results. How does light and sodium bicarbonate impact the rate of photosynthesis in spinach leaf discs? 3. Identify the controls used in this experiment. Which control is positive, and which control is negative?

The light source gives light energy, this solution gives water, and sodium bicarbonate gives CO2 in dissolved form.  

The leaf disc/plate utilizes light energy for photosystem II and I for their ATP and NADPH creation and sodium carbonate gives CO2 to Calvin cycle. SO photosynthesis will take place.  

conclusion -  

The Positive control here, the light and Co2 level continuously increment so in a medium the photosynthesis is increased.  The leaf disc are floating at first after sometime CO2 are utilized so there is lack of CO2 it not ready to experience photosynthesis the disc began to settle down.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
