The human populations are not limited by the carrying capacity of their ecosystems, and they are the only species on Earth that are able to perform such a thing. The main reason for this is that the humans are able to transport resources of all sorts and for all needs from very distant places. Even if there's a very large population surrounded by desert, the humans are still able to survive by simply bringing in the necessary things from other places throughout he means of transportation. Another reason is that the humans are able to change and manipulate their environment to certain extent, being able to provide for themselves even in ecosystems that naturally are nowhere near close to provide those things for them.
Answer:
This question includes some errors, the question should be written as:
The medulla oblongata controls the contraction and relaxation of the ______ causing the lungs to inflate and deflate during breathing.
Although there are no options, the answer is generally RESPIRATORY MUSCLES i.e. diaphragm and intercostal muscles
Explanation:
Breathing is an involuntary action required to take place in order to get oxygen into the system and carbon dioxide out of the system. However, the process of breathing is neurally controlled by brain portion called RESPIRATORY CONTROL CENTERS.
The Medulla oblongata located in the hindbrain is one of the two respiratory control centers (the other being the PONS). The medulla sends nerve signals to the muscles responsible for bringing about the ventilation process i.e. the DIAPHRAGM and INTERCOSTAL MUSCLES.
This nerve impulse brings about the contraction of the diaphragm, which is the major respiratory muscle, and intercostal muscle causing the lungs to inflate and allow the entry of oxygen-containing air. On the other hand, it also brings about the relaxation of these muscles causing the lungs to deflate allowing the expelling of air.
