Answer:
i think its A thats correct
An increase in volume DECREASES the pressure in the chest (pressure and volume vary inversely when temperature is held constant -- Boyle's law). Gas can only flow from an area of higher pressure to an area of lower pressure. It can't go uphill -- ever. It can only go from high to low pressure. When the diaphragm and intercostals contract, the diaphragm flattens and the rib cage rises. That increases the volume of the chest. That increase in volume decreases the pressure inside the chest (temperature is held constant -- because the temperature of the chest cavity does not change appreciably. It remains at body temp.). Air then flows from the area of higher pressure (atmospheric) to lower pressure (intrathoracic). That continues until the pressures are equal.
When the diaphragm and intercostals relax, the chest cavity decreases in size, the pressure increases to above atmospheric, and gas flows again from the area of higher pressure (intrathoracic) to lower pressure (atmospheric) until they are again equal.
It has nothing to do with the concentration of oxygen. You can ventilate a lung with ANY gas. It has to do with the change in pressure and only the change in pressure -- which is a function of the volume of the chest cavity.
Bio means life; biology is the study of life and a biography is the story of someone's life.
Chloro means green, as in chlorophyll, which is found in green plants.
Lol it wouldn't let me edit before, sry :)
<span>Cytosis requires energy, and the production of energy depends on oxygen. Diffusion does not require energy.</span>
Answer:
genetic information, energy, soil
Explanation:
Germination is the term used to describe the set of steps that allow the development of an embryo within the seed of the plant. The development of this ambrion will result in the emergence of a seedling that will develop and form a very important plant for the ecosystem. In short, germination is the process of transforming the seed into a new plant.
In order for this to occur, the seed needs some factors that degrade its entire development. These factors are genetic information, energy and soil
