The answer is; concentration of oxygen and/or total atmospheric pressure is lower at high altitudes

This means that at high altitude, due to the low pressure, every breath has a lower oxygen content than at a lower altitude. This, therefore, necessitates the body to increase the erythrocyte numbers in the blood to maximize the uptake of oxygen from the thinner air.

ludmilkaskok [199]

Answer:

Convergent Evolution

Explanation:

Convergent evolution occurs when two unrelated species that have no common ancestor evolve independently in order to adapt to a similar environmental constraints to ensure survival.

An example of convergent evolution can be seen in birds, bats, flight/wing insects. They all do not share a common ancestor, but have evolved, separately, a similar structure for flight.

Another example can be seen in dolphins and sharks. These two different species share similar physical characteristics that make them adapt well in marine habitat that helps them to predate .

■Here,The corn syrup is hypertonic to the carrot, so will take water from the adjoining cells, causing those cells to shrink, become hypertonic to their neighboring cells and to take water from them.

■Conversely the water is hypotonic, and will enter the cells in the outer of the carrot.

■Because of this water will pass from the outside of the carrot to the inside, and cause liquid in the tube to rise
