Because each subject in an experiment has to have equal conditions to ensure the most accurate results. And water temperature is known to impact plant growth. An experiment using different water temperatures is a terribly inaccurate experiment.
<h2>Visceral pleura</h2>
Explanation:
The portion of the serous membrane that covers and adheres to the lung is called visceral pleura
- Pleura are the pair of membranous linings surrounding the lungs
- The visceral pleura covers each lung surface, and the parietal pleura covers the inner surface of the thoracic cavity
- The visceral pleura is a delicate membrane which dips into the fissures between the lobes of the lung
- Pleura allows the lungs to move inside the body cavity without friction as friction would cause damage to the lungs and the tissue in the chest wall
Worldwide circulation and reutilization of carbon atoms, chiefly due to metabolic processes of living organisms. Inorganic carbon, in the form of carbon dioxide, is incorporated into organic compounds by photosynthetic organisms; when the organic compounds are broken down in respiration, carbon dioxide is released. Large quantities of carbon are "stored" in the seas and the atmosphere, as well as in fossil fuel deposits.
The answer is C. Population size
