The most common colors of bell peppers are green, yellow, orange and red. More rarely, brown, white, lavender, and dark purple peppers can be seen, depending on the variety. Most typically, unripe fruits are green or, less commonly, pale yellow or purple. Red bell peppers are simply ripened green peppers, although the Permagreen variety maintains its green color even when fully ripe. As such, mixed colored peppers also exist during parts of the ripening process. Green peppers are less sweet and slightly more bitter than yellow or orange peppers, with red bell peppers being the sweetest. The taste of ripe peppers can also vary with growing conditions and post-harvest storage treatment; the sweetest fruits are allowed to ripen fully on the plant in full sunshine, while fruit harvested green and after-ripened in storage is less sweet.
are green bell peppers just unripe red bell peppers?

Answer: yes

Pulmonary surfactant is a surface-active lipoprotein complex (phospholipoprotein) formed by type II alveolar cells. The proteins and lipids that make up the surfactant have both hydrophilic and hydrophobic regions. By adsorbing to the air-water interface of alveoli, with hydrophilic head groups in the water and the hydrophobic tails facing towards the air, the main lipid component of surfactant, dipalmitoylphosphatidylcholine (DPPC), reduces surface tension.
surfactant is released to reduce surface tension in the alveoli?
