Yes, evolution through selection procedure better organism in an absolute sense and yes, we are climbing the Scala nature
Explanation:
The process of natural selection influences the production of beneficial organism in a population. in this process organism with great evolutionary adaptation are produced. the organism which has better fitness in evolution has a great contribution in a gene pool.
Diversifying, directional, stabilizing, sexual etc are various ways in which the process of natural selection affects the variation and quality of traits in the population.
In pneumonia, the accumulation of pus and/or fluid will thicken the respiratory membrane and slow down the diffusion rate. This would decrease the amount of oxygen taken up by the blood.
<h3>How does pneumonia affect diffusion in the alveoli?</h3>
Pneumonia is caused by an infection, and a wide variety of microbes can infect the lungs. Pneumonia is typically brought on by bacteria or viruses, but it can also be brought on by fungus and other organisms. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing.
In alveoli, blood is given oxygen and carbon dioxide is expelled. Pneumonia causes the alveoli in one or both lungs to swell with fluid and pus (exudate), obstructing normal gas exchange. Consolidation and collapse of the lung is another name for this. Diffusion is the method used for gaseous exchange at the alveoli.
