Why does the carbon dioxide level fluctuate during a single year?
The carbon dioxide level fluctuates during a single year due to seasonal changes in plant growth and decay, which affect the amount of carbon dioxide absorbed and released into the atmosphere.
Why do atmospheric carbon dioxide concentrations fluctuate seasonally?
Atmospheric carbon dioxide concentrations fluctuate seasonally due to the natural processes of photosynthesis and respiration in plants. During the growing season, plants take in carbon dioxide for photosynthesis, which reduces the amount of CO2 in the atmosphere. In the winter, when plants are dormant, there is less photosynthesis and more respiration, leading to an increase in atmospheric CO2 levels.
What drives the movement of carbon dioxide from tissue into the bloodstream?
Movement of carbon dioxide is driffen by osmosis from and to the tissue and bloodstream. Also active transport can be used. Amount of CO2 present is monitored by means of the pH of your blood as dissolved CO2 is acidic.
What blood level is most significant in regulating the respiratory center of mammals?
The levels of carbon dioxide in the body are monitored by chemoreceptors, (they do this by measuring pH - lower pH means more carbon dioxide). If the levels of carbon dioxide are too high then the respiratory centre of the brain (in the medulla oblongatis) sends signals to the lungs and diaphragm to increase the breathing rate.
What gas must be monitored in the atmosphere to make sure it is not too high or low?
Carbon dioxide has to be monitored as it is a greenhouse gas. Too much causes global warming. Too little will mean that the earth will cool, even freeze.
What gas is exhaled from the lungs?
carbon dioxide
Can the human experiment 'How Plants Made the World' be perfect?
No, both the box and the human being will need to be monitored strictly. Pressure changes in the box need to be monitored more precisely as the oxygen, carbon dioxide, water vapor, temperature etc.
Is carbon dioxide an element or carbon?
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
What are the operational definitions for carbon dioxide?
CO2, or Carbon Dioxide, is a colourless and odourless gas. It is formed as a result of respiration by animals and by the decomposing of organic substances. It is then absorbed by plants and used in the process of photosynthesis (in which the plant releases oxygen back into the air).
What gas is produced by respiration?
Carbon dioxide is produced as a byproduct of cellular respiration in organisms, including humans and animals. During respiration, glucose is broken down in the presence of oxygen to produce energy, water, and carbon dioxide.
What gas is given off by cellular respiration?
Carbon Dioxide
What is the name of this compound CO 2?
CO2 is the chemical formula of carbon dioxide.
