The mesothelial cells of the pleural membrane create pleural fluid which serves two purposes:
Lubrication

Answer:
Mimicry
Explanation:
In mimicry, species evolve to resemble other species; in Müllerian mimicry this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as wasps able to sting) come to advertise their defences in the same way. Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight.
Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects.
Answer:
The cell wall provides the cell with protection from all the unfavorable conditions. ... Without the cell wall, the plant cell will collapse. Uptake of nutrients would be tough and the cell would be without any protection. Hence the plant would eventually die.
Explanation:
Digestion of the sugar athelose in this theoretical framework is controlled by an operon that displays both positive control and negative control. Translation of the ath operon is turned on when athelose is available, and accelerated when the bacterium comes up short on glucose and must depend on athelose for vitality.
