A certain species of salamander was split into two populations by a wide, dry valley, and the populations began to diverge from

each other. After a period of time, some members of the two populations began to interbreed in a hybrid zone at the southern end of the valley. Only weak reproductive barriers existed by this time, so the two populations could freely interbreed and re-establish gene flow. This outcome in a hybrid zone is known as __________.

Answer:

This outcome in a hybrid zone is known as <u><em>fusion</em></u>.

Explanation:

In the field of biology, hybrid zone can be described as the area where closely-related species can interbreed and produce hybrid organisms. Reinforcement can be described as the phenomenon by which a hybrid zone develops between full species barriers. Hybrid speciation can be described as the phenomenon by which a new species forms as the direct result of mating between members of two existing species.

Delicious77 [7]

The reading of the blood pH value of 6.4 indicates a health issue because of the pH value. It is because the concentrations of H+ ions in the body becomes 10 times more than the usual level in the body.  

The pH of the blood becomes less than 7.35 due to enhanced production of hydrogen ions by the body or the incapability of the body to produce bicarbonate ions in the kidney, the condition is known as metabolic acidosis that eventually results in acidemia.
