Answer:
The correct answer is - phagocytes engulf the pathogens and release several inflammatory mediators.
Explanation:
Phagocytes that are present in the immune system are neutrophils, eosinophils, macrophages and the dendritic cells that perform a multistep process that eliminate the pathogen or toxic substance from the site of injury.
Neutrophils and macrophages are the essential phagocytes that play a major role in healing the wound. Neutrophils are phagocytic cells that reach the site of injury first and ingest the bacteria, cellular debris or dead cells and eliminate from the site. These phagocytes also release some inflammatory mediators to help in the process of inflammation.
Macrophages reach to the site of the wound and play a similar role as the neutrophils as they also remove debris and release the inflammatory mediators however they remain for longer time at the site of injury.
Thus, the correct answer is - phagocytes engulf the pathogens and release several inflammatory mediators.
Hello.
The answer is: A.Ultraviolet rays from the Sun converted dissolved carbon dioxide to oxygen.
the more carbon dioxide that people pumped into the atmosphere by burning fossil fuels, the more the oceans would absorb. The ocean would continue to soak up more and more carbon dioxide until global warming heated the ocean enough to slow down ocean circulation.
Have a nice day
Answer: 1. Cambrian period, 5. rotation at the shoulder joint. 3. d. notochord, 4. d 2. d.
Explanation:
<span>The abundance and variety of fossils in Phanerozoic rocks have allowed geologists to decipher in considerable detail the past 600 million years or so of the Earth’s history. In Precambrian rocks, however, fossils are rare; thus, the geologic record of this important part of the Earth’s history has been especially difficult to decipher. Nonetheless, stratigraphy and radiometric dating of Precambrian rocks have clearly demonstrated that the history of the Earth extends billions of years into the past.</span>
