Answer:
I would not call this an emergency. it seems like a second degree burn which can be treated with aloe Vera and antiseptic spray.

FULL ARTICLE
Density-independent factor, also called limiting factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area). Density-independent factors often arise from physical and chemical (rather than biological) phenomena.

Such factors stemming from weather and climate—as well as flooding, wildfires, landslides, and other disasters—affect a population of living things whether individuals are clustered close together or spaced far apart. For example, for most organisms that breathe oxygen, oxygen availability is a density-independent factor; if oxygen concentrations decline or breathable oxygen is suddenly made unavailable, such as when oxygen-using plants are covered by rising floodwaters, those organisms perish and populations of the various affected plant species decline.
The dynamics of most populations of living things are influenced by a combination of density-independent factors and density-dependent factors (that is, those factors that emerge when the concentrations of individuals in a population rise above a certain level). The relative importance of these factors varies among species and populations.
Diffusion is helping these gases to do the gas exchange at alveoli, and blood capillaries. And diffusion depends on partial pressure because it is the pressure produced by the gas in a mixture when it occupied by its own volume.
Explanation:
- In a body, the gas exchange will occur in two places, one is lungs where oxygen will take and carbon dioxide will release into the respiratory membrane. The second place the tissues where the oxygen is released and the carbon dioxide is taking.
- In external respiration, exchanging gases with the external environment and this occurs in the alveoli of the lungs. In the internal respiration, change of gases will happen with the internal environment and occurs in the tissues.
- The exchange of gases is happened because of the simple diffusion. Diffusion is the process at which the gas-particle will move from high concentration to low concentration.
- there is no energy required to move carbon dioxide or oxygen between the membranes. Because they will create a pressure gradient which allows them to diffuse between the membranes.
