Answer:
The correct answer is 6.67 %.
Explanation:
The average osmotic pressure of the brain is 300 mM
Given the concentration of solution is 280 mM
Difference is 300 - 280 = 20 mM
This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.
Also, it is known that the volume of brain is about 1200 ml on an average,
Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml
Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %
In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.
ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.
Answer:
As light intensity increases to 800 (units), the rate of photosynthesis also increases. This is because a higher light intensity results in an increased rate of the light dependent reaction. However, when light intensity increases above 800, the rate of photosynthesis remains constant. This is because the light intensity is no longer the limiting factor, meaning that something else must be limiting the rate of photosynthesis. This could be carbon dioxide concentration or water availability. CO2 is required for the light independent stage of photosynthesis (the Calvin cycle) whereas water is required to produce H+ and e- for the electron transport chain.
Explanation:
I hope this would be enough to get the 4 marks. The main point is that the rate does not increase each time light intensity increases, because there is a limiting factor that is affecting the rate of the light independent reaction.

sucrose, the scientific name for table sugar, is more complex than a monosacchande.
