it is option - B - An abandoned field
Sister chromatids separate during anaphase
According to the image, the fish underwent sympatric speciation. The new species of fish had mating seasons that were different from that of the original fish. Because of the differences in mating seasons, the fish underwent reproductive isolation. This mode of isolation would be temporal.
Sympatric speciation happens within a population of an organism that gets isolated reproductively due to differences in their mating periods. This time dependent isolation is called temporal isolation. Example, a fish population can split into two if some of the fishes start mating early in the spring while the rest mate late in the autumn. The spring-mating population will not become compatible to mate with the late-autumn-mating population.
Answer: Some of the intestinal symptoms elicited by pathogens such as salmonella, shigella, and Escherichia are due to the presence of lipopolysaccharides.
Pathogen associated molecular patterns binds to toll like receptors to elicit a response include lipopolysaccharide or LPS. The bacterial component interaction with the host involves LPS and other components of cell wall causing a septic shock. The triggering of any event of septic shock is directly related to the release of LPS or other bacterial toxins into circulation. Pathogen associated molecular patterns are the molecules which are made by the pathogen and needed for their survival or pathogenic character includes LPS.
