Answer:
To be sustainable is to be able to maintained at a certain rate. It's to keep things continuous and viable. For example, wind energy is sustainable compared to oil because wind is easier to get than oil. Another example is if a country only has about 10-13 crimes a year for 20 years, crime is sustainable in that country.
Photosynthesis requires a few main components. Mainly, Sunlight, Water and Carbon dioxide.
For this reaction, the reactants are
1) Water
2) Carbon dioxide
For water, it enters the cell by Osmosis. Water enters a cell through a partially permeable cell surface membrane.
When water enters a space through a partially permeable membrane from a high water potential to a low water potential, the process is called osmosis.
For carbon dioxide, it enters the cell through diffusion.
Diffusion involves particles moving from a region of higer concentration to a region of lower concentation. Therefore, the answer is Diffusion.
Extra knowledge:
Carbon dioxide dissolves into the thin film of moisture on the surface of the spongy mesophyll layer for easy transportation to the cells involved in photosynthesis.
A. Harmful algae bloom is being put in there
Prostatic acid phosphatase was purified from prostatic fluid. Monospecific antisera to the purified acid phosphatase was then produced in rabbits. When antibody was coupled with acid phosphatase, the enzymatic activity was markedly stabilized against pH and temperature degradation. Both acid phosphatase and rabbit anti acid phosphatase were non specifically coupled to Sepharose-4B using cyanogen bromide. Under these circumstances slight stability occurred when antibody was bound to Sepharose, and then acid phosphatase added to the gel antibody complex. When acid phosphatase was complexed to Sepharose, no stabilization occurred.
