Answer:
“Geoneutrinos,” neutrinos that stream naturally from the Earth’s interior, are giving scientists the best direct evidence of what’s at work in the belly of the planet. Released by naturally occurring radioactive isotopes inside the Earth, geoneutrinos carry information about what makes the Earth’s insides hot; what elements make up the core of our planet and in what concentration and distribution; how the Earth’s mantle and tectonic plates move and interact; and how planets like our own form and evolve.
Answer:
they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
The walls of the alveoli are only one cell thick. This makes the exchange surface very thin - shortening the diffusion distance across which gases have to move. Each alveolus is surrounded by blood capillaries which ensure a good blood supply.Adaptations of the alveoli:
Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through.
