Lorico [155]2 years ago

The correct answer is D. Lower birth rates

Explanation:

The growth rate is determined by how fast the population of a country or a zone increases. This factor is higher in developing countries than in developed countries. One factor that contributes to this is the low birth rate in developed countries as people have fewer children in these countries, and therefore there are fewer births per year than in developing countries. This is influenced by the accessibility to contraceptive methods, higher education levels, and cultural values. Also, fewer births mean the population will grow slowly, and therefore the growth rate is lower.

SSSSS [86.1K]

Answer: Acid rain

The volcanic eruption is a natural phenomena that results in the liberation of the lava from the heap of the earth along with the gases. The volcanic eruption causes major damages to the vegetation lying above the erupted crater of the volcano.

Jon likes hiking. He observes that whenever he hikes up a hill he breathes heavier than when he is on flat ground. Which 2 state
Alekssandra [29.7K]

Answer:

-Sensors in the brain detect a lack of oxygen.

-The muscles in his body need more energy and therefore more oxygen.

Explanation:

-Sensors in the brain detect a lack of oxygen.

-The muscles in his body need more energy and therefore more oxygen.

-The body has too little carbon dioxide to maintain function.

-The body is using carbon dioxide instead of oxygen to make energy.

-Blood pressure has decreased, so less blood is being pumped to the muscles.

<em>The correct answer would be that </em><em>sensors in the brain detect a lack of oxygen</em><em> and t</em><em>he muscles in the body of Jon need more energy and therefore, more oxygen.</em>

At sea level, the atmospheric pressure easily allow oxygen to permeate the cells of the lung and diffuse into the blood. At high altitudes, air pressure is generally lower and permeation/diffusion through the cells of the lung into the blood becomes difficult.

<u>Without adequate oxygen, the body cannot generate energy needed for physical activities of muscles. Consequently, the sensors in the brain detect a lack of oxygen and the body system reacts by breathing heavily to compensate for the oxygen shortage.</u>
