Answer:
(B) open stomata only at night, limiting water loss because of heat and low humidity.
Explanation:
CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.
They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.
During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.
Answer:
<u>The correct statements are A and D</u>
A.The photo-system will still continue to split water because it is still losing electrons
D.The ATP yield would be unaffected
Explanation:
DCPIP is a redox-sensitive dye, not an electron transport chain blocker, and hence, imparts change in the wavelength when electrons are transferred. This allows rest of the steps of photo-system to be carried on normally, including splitting of water to generate oxygen as well as generation of ATP.
Answer:
In the presence of oxygen, respiration of yeast produces carbon dioxide and water. In the absence of oxygen, respiration of yeast produces carbon dioxide and alcohol.
Under the assumption that the yeast has insufficient exposure to oxygen in the surrounding air in the testtube, alcohol and carbon dioxide would be expected to be found in the test tube
