The final choice seems to be the last one, but I think it could also be the first one
Answer:
The respiratory system is comprised of specialized organs and structures for gas exchange in both animals and plants. The structure and function of this system differ significantly based on the organism's size, habitat, and evolutionary background. In terrestrial animals, the respiratory surfaces are typically the linings of the lungs. In mammals and reptiles, gas exchange occurs within millions of tiny air sacs known as alveoli, while birds have atria for this process. These tiny air sacs boast an extensive blood supply, ensuring air comes into close proximity with the bloodstream. They connect to the outer environment through airways or hollow tubes, with the trachea being the largest that divides in the chest into two primary bronchi. These then branch further into successively narrower secondary and tertiary bronchi, eventually leading to numerous smaller tubes called bronchioles. In birds, these are referred to as parabronchi. The air needs to be drawn into the alveoli or atria from the outside through the act of breathing, which involves respiratory muscles.

Explanation:
Rôche moutonnée (or sheepback) is a geological structure shaped by the movement of an ice mass. The movement of the ice over the bedrock typically results in varying erosion patterns due to abrasion on the "stoss" side (upstream) of the rock and plucking on the "lee" side.<span> A terminal ground<span> </span>is also known as final ground<span>, and it is a form of ground<span> that emerges at the edge (snout) of an </span>ice mass<span>, marking the region of its </span>farthest reach.</span> Currently, it consists of debris<span> that has been gathered through plucking and abrasion.
