The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion. Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms - including all plants and animals - release energy from their food using respiration.-BBC.CO.UK
Plants and other things that make food for themselves and use the sun to make food
Answer:
Other scientists would need to confirm the results by performing the same experiment.
Explanation:
According to this question, an experiment was conducted by an associate professor, using 20kids, to discover why children are better at problem-solving after exercise. He arrived at a result that Children who exercised showed a 5% increase in the P3 waves, which occur during decision- making.
However, in order for this findings by Charles Hillman to be generally accepted and recognized in the scientific community, which is a connection of several scientists, the results need to be confirmed by performing the same tests or experiment.
Note that, an experiment becomes a scientific theory if it has undergone series of repeatable tests. One of the key features of scientific experiment is that it must be repeatable.
Cloud seeding
Another instance where supercooled and mixed-phase clouds are studied extensively is related to cloud seeding and weather modification. Cloud seeding involves the addition of aerosol, such as silver iodide aerosol, that modifies the phase and size distribution of hydrometeors. The goal of cloud seeding is to alter the natural development of the cloud to enhance precipitation, suppress hail, dissipate fog, or reduce lightning. Various cloud seeding techniques are employed, as particles are released from rockets, aircraft, or ground. The seeding of ice-phase clouds can induce the phase transition from a supercooled water cloud to one composed of ice. In the case of dynamic cloud seeding, the purpose is to stimulate vertical air motions through increased buoyancy caused by the release of latent heat of freezing (Hobbs, 1975; Cotton and Pielke, 1995).
The cell wall of <em>Mycobacterium </em>is accountable for its slow growth, being <em />strongly impermeable to nutrients, and for its compact, wrinkled appearance in colony morphology. Most nutrients are hydrophobic such as certain fats and vitamins as well as some form of carbohydrates and proteins. Since the cell wall is hydrophobic, nutrient absorption of <em>Mycobacterium</em> is slow hence growth of the organism is also slow. A wrinkled colony appearance is also characteristic of microorganisms with hydrophobic cell walls.
On the other hand, while <em>Mycobacterium</em> is an aerobic organism; the hydrophobicity of the cell wall do not account for this characteristic of the organism.
