Answer:
Negative feedback.
Explanation:
The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.
Yeah I can help with that

<h3>What are Homo erectus?</h3>
Homo erectus, an extinct species of Pleistocene archaic human, first appeared about 2 million years ago. Several human species, including H. heidelbergensis and H. antecessor, seem to have diverged from H. erectus, with the former being largely accepted as the ancestor of Neanderthals, Denisovans, and modern humans. Among the first recognizable representatives of the genus Homo are its specimens. The first known ancestor of modern humans, H. erectus, had a continental range that stretched from the Iberian Peninsula to Java. H. floresiensis and possibly H. luzonensis may have its origins in Asian populations of Homo erectus. H. erectus soloensis, from Java, dates to a time period between 117,000 and 108,000 years ago.
