Sati [7]3 years ago

Alveolar walls are thin to enable the quick passage of oxygen in and out of the lungs. The lungs works hand-in-hand with the heart and also is responsible in converting blood that's de-oxygenated into an oxygenated blood that is usable by the organ systems of the body. The alveolar walls are also designed to have thin membranes so that it can expand and constrict quickly allowing us to breather properly.

Why would a third-degree burn be less painful than a first- or second-degree burn involving the same body area?
Irina18 [472]
A third-degree burn would be less painful than a first- or second-degree burn involving the same body area because of the destruction of underlying pain receptors.
Nerve endings are destroyed in third-degree burns, which means that a person can no longer feel pain in that particular spot on the body. Third-degree burns are the most severe ones and cannot be treated easily - usually skin grafting or synthetic skin has to be used to replace the burnt skin.

Which of the following describes how a plant’s root system and shoot system work together?
MissTica

Answer:

The root and shoot systems facilitate the ability to absorb, CO2, light, water, and minerals. The root system consists of the roots, and the shoot system consists of the stems and leaves. Angiosperms and vascular plants rely on these two systems. Roots are nonphotosynthetic and starve unless photosynthesates are absorbed through the shoot system. The shoot system depends on the roots to absorb nutrients.
