This happens when a detection is accomplished through heuristics. There is no such thing as a heuristic virus. As a technical concept, everything in malware detection is done via heuristics.
Photosynthesis is the process in which plants (also autotrphoic protists and some bacteria) use light energy, from the Sun, to make sugars and organic food molecules from CO2 and water (H2O). This process is essential for the formation of not only energy, but also for the formation of glucose for purposes of structure.
1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis. 2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose. This carbon dioxide will be supplied by sodium bicarbonate dissolved in the water with the plant leaf disks.
