The most likely complication of this disease is the development of Empyema.
Explanation:
The patient has symptoms of fever, dyspenea (breathlessness with chest pain), cough and sputum which directs towards empyema as they are symptoms of pneumonia and prolonged symptoms would cause empyema.
The infiltrates in the posterior segments of upper lobe of the right lung results in bulging fissure causing necrosis lesion which would cause the complications of empyema.
The empyema is the condition in which pus cells are formed in thoracic cavity, in pleural fluid bacterial infection occurs due to pneumonia or surgery of chest.
The empyema risk is high for diabetics, pulmunary infected and alcoholism.
Answer: Hypertonic Environment
Explanation:
The salt solution and sugar solution is used for the process of food preservation as the bacteria and microorganism are not able to grow in such conditions that is being created by the solution.
The amount of the solute is more and the solution is less concentrated. The bacteria cell has less solutes and more solvent.
As per osmosis the water from the salt or sugar solution moves out from bacterial cell shrinks and dies.
This is how the bacterial cell dies and the food is prevented from spoilage.
Answer: genetics and mutation generate some of the variety that natural selection acts on
Explanation:
The crayfish have its nerve cord on the ventral side rather than on the dorsal side. The ventral side is under the Crayfishes' exoskeleton, as opposed to the dorsal side where the exoskeleton is . If it is attacked it will be from the dorsal side and the nerve cord would be snapped easier. The function of the nerve cord is that if it gets attacked by a predator they will go for the top and it will still be able to move.
