What is the main fuction of the kerbs cycle?
FADH2
How have humans contributed to the increase in carbon dioxide in the atmosphere in the last century?
Humans burned and continue to burn fossil fuels (coal, oil and natural gas) in industry, travel and to generate electricity. This releases extra carbon from millions of years ago.They also destroyed forests all over the world that used to absorb carbon dioxide from the atmosphere.
What are the conditions of the Krebs cycle?
The kreb's cycle is ESSENTIAL without it humans would not exist. The kreb's cycle is what makes the majority of energy in the body. The only other path is fermentation which occurs if glycolysis takes place in the absence of oxygen. This does not provide nearly enough energy which is why humans need oxygen.
Which is the reference carbon atom in sugars?
The last chiral carbon.
How is the human activity upsetting the natural balance of the carbon cycle?
The carbon cycle takes CO2 from the atmosphere in various ways, and then releases it back into the atmosphere. This is a balanced process, so there is always the same amount of CO2 in the atmosphere. This supports the natural greenhouse effect which has kept the planet warm for millions of years.Human activity (deforestation and the discovery and burning of fossil fuels) is upsetting the natural balance. We cut down trees so more CO2 is left in the air. Burning fossil fuels releases carbon emissions that have been safely hidden underground for millions of years, so they are an extra burden. So the natural balance of the carbon cycle is upset, and we have global warming.A:Through industry and transportation we release excess CO2 into the atmosphere, too much for vegetation to soak up so it stays in the atmosphere, making it thicker.
What is the length of the estrous cycle in pigs How does this compare with humans?
The estrous cycle of pigs is 21 days. Humans have a menstrual cycle which can last from 21-35 days.
What are some possible causes for the changes in the amount of carbon dioxide in the atmosphere?
The most obvious and indisputable cause in the last 150 years is the addition of carbon through fossil fuels and land cover changes by humans. Other causes are changes in the carbon cycle, minor by comparison. This includes a global ability to uptake more carbon in forests, as well as the inability for the oceans to take anymore carbon.
What is the last step of the Calvin cycle?
The last step of the Calvin cycle is regeneration, in which molecules of glyceraldehyde-3-phosphate as well as ATP are used in order to recreate ribulose biphosphate, the original carbon dioxide acceptor in the cycle.
What are some reasons why the carbon cycle become unbalanced in the last milloin years?
Because how human activity
What is the main fuction of the kerbs cycle?
FADH2
What happened on the last day of the Aztec 52- year cycle?
The gods decided whether to destroy humans and the world.
What is the importance of the carbon cycle?
It is recycled in the world as there is only a certain amount. It also allows us to do carbon dating using the rate at which carbon decays as we know that the amount of carbon in the atmosphere has stayed level throughout the last couple of milleniums.
How do you describe carbon and oxygen cycle?
The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates. In cellular respiration, carbohydrates are broken down to form ATP and carbon in the form of carbon dioxide is released into the atmosphere.The two processes of the oxygen cycle are also photosynthesis and cellular respiration. In photosynthesis, oxygen is produced by the splitting of water and is released into the atmosphere. Oxygen is used in the process of aerobic cellular respiration as the last electron acceptor in the electron transport chain. The oxygen then combines with hydrogen to form water molecules, which can then be used by photosynthesis and the cycle is complete.
What are disadvantages of using synthetic oil in 2 cycle outboards?
None, except price. Synthetic will create less carbon and your spark plugs will last longer. I use synthetic in all my 2 cycle engines.
How does the life cycle of a star compare to the life cycle of a human?
Stars go through stages like birth, main sequence, red giant, and death, which can last millions or billions of years. In comparison, humans have a much shorter life cycle, typically living for decades. Both stars and humans undergo changes over time and eventually cease to exist.

Will the water cycle last for ever?
Water cycle is a continuous process. It will last long.
