Answer:
24 molecules
Explanation:
All the carbon in the sugar comes from CO2. 6 molecules of CO2 need to be fixed to form 1 molecule of glucose (a 6 carbon sugar). So 24 molecules of CO2 should enter the calvin cycle to produce a sugar that has 24 carbon atoms.
Answer:
Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.
Fortunately, transportation technologies and strategies are emerging that can help to meet the climate challenge. These include automotive and fuel technologies, intelligent transportation systems (ITS), and mobility management strategies that can reduce the demand for private vehicles. While the climate change benefits of innovative engine and vehicle technologies are relatively well understood, there are fewer studies available on the energy and emission impacts of ITS and mobility management strategies. In the future, ITS and mobility management will likely play a greater role in reducing fuel consumption. Studies are often based on simulation models, scenario analysis, and limited deployment experience. Thus, more research is needed to quantify potential impacts. Of the nine ITS technologies examined, traffic signal control, electronic toll collection, bus rapid transit, and traveler information have been deployed more widely and demonstrated positive impacts (but often on a limited basis). Mobility management approaches that have established the greatest CO2 reduction potential, to date, include road pricing policies (congestion and cordon) and carsharing (short-term auto access). Other approaches have also indicated CO2 reduction potential including: low-speed modes, integrated regional smart cards, park-and-ride facilities, parking cash out, smart growth, telecommuting, and carpooling.

Answer:
Cellular respiration
Explanation:
All living cells strictly require energy in form of ATP to perform their cellular functions. This energy is obtained when food molecules are broken down on their cells in order to release the stored energy in their bonds. This anabolic process is called CELLULAR RESPIRATION.
CELL CYCLE is one of the cellular functions performed by a cell, as every cell needs to undergo division. According to this question, the cell cycle requires energy, which is also supplied via the process of CELLULAR RESPIRATION.
