Answer;
Hot & Dry conditions
Explanation;
-C4 is the alternative pathway of Calvin cycle (C3 cycle) taking place during the dark phase (light-independent stage) of photosynthesis. In the C4 cycle the first stable compound is 4 carbon compound, namely oxaloacetic acid. Hence it is called C4 cycle. It is a process of carbon dioxide fixation.
-C3 plants have the disadvantage that in hot dry conditions their photosynthetic efficiency suffers because of a process called photorespiration. When the CO2 concentration in the chloroplasts drops below about 50 ppm, the catalyst rubisco that helps to fix carbon begins to fix oxygen instead.
-The problem of photorespiration is overcome in C4 plants by a two-stage strategy that keeps CO2 high and oxygen low in the chloroplast where the Calvin cycle operates.
Answer: Warm-Up:
Write down two places in the school where
you think there might be a lot of bacteria,
and write down two places in the school
where you think there will be very little
bacteria. Explain why you chose these
places.
Explanation:
There is a lot of bacteria in the restroom because it is they restroom of course and there is a lot of people who go in and out through out the day. Some people do not wash their hands after using the bathroom, also from other places. One of the most cleanest areas might be the science lab because they are always cleaning up everything and disinfecting.
