Answer:
The correct answer is: Type 1 Pneumocytes, and Type 2 Pneumocytes.
Explanation:
The alveoli are structures that form a hollow cavity and are found in the lungs. Alveoli have the very important task of gas exchange, in which deoxygenated blood becomes oxygenated blood to be distributed to every organ in the body.
Alveoli walls are composed of two types of cells:
- Type 1 Pneumocytes have the function of gas exchange between the capillaries, and for that reason, they are very thin and permeable.
- Type 2 Pneumocytes have the function to produce surfactant, a substance very important to maintain the elastic recoil of the lungs. Without surfactant, the lungs would collapse.
Answer:
The correct answer is - C. An increase in the sustainability of an ecosystem.
Explanation:
Biodiversity is the variety of different biological species and populations on the earth or in an ecosystem. Biodiversity helps in maintaining health by providing food and other resources. Higher biodiversity healthier the earth.
Sustainability is the ability to maintain the ecological process and its structure and function in case of external stress for a longer time. The more sustainability of an ecosystem the healthier the ecosystem. The biodiversity of an ecosystem provides sustainability to the ecosystem. An increase in biodiversity will lead to a more sustainable ecosystem.
