The answer is b. it is a product formed. Photosynthesis is being done with the use of light, carbon dioxide and the water. This then will have an end product which is glucose which then can be use as a food source. Hope this answer would be of help.
Answer:
C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. This step takes place in the mesophyll cells that are located close to the stomata where carbon dioxide and oxygen enter the plant.
Explanation:
The question is incomplete, so the complete question is as follows:
A chloroplast has stopped producing ATP and NADPH. Which of the following is most likely causing this?
a.The chloroplast has used up its supply of chlorophyll molecules.
b.Electrons have stopped moving through the electron transport chain.
c.The sun has risen and the chloroplast now can make more chlorophyll.
Answer:
b.Electrons have stopped moving through the electron transport chain.
Explanation:
ATP and NADPH are produced in the light dependent reaction stage of the photosynthesis that occurs within chloroplast grana.
ATP and NADPH are produced due to the movement of electron and proton (H+) in the electron transport chain, so if the movement of electrons will stopped in the electron transport chain, the formation of ATP and NADPH will also get stop.
Hence, the correct answer is "b".
Answer:
Option C, It mandates the clean-up of abandoned hazardous waste sites.
Explanation:
A superfund was a programme launched by federal government in America to clean up hazardous and abandoned waste sites. The different sites that are managed under this programme are called as superfund scheme. It is also known as "Comprehensive Environmental Response, Compensation, and Liability Act, 1980"
Based on the hazardous ranking evaluated by the EIA team, CERCLA status of the site is determined . The site with highest score was dealt on priority basis.
Hence, option C is correct.
