Tracheal intubation. Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs.
Shade â Moss also likes to grow in the shade, which makes sense as moisture is more likely to linger in these areas and the moss will be less likely to dry out quickly. Acidic soil â Moss also likes soil with a higher acidity, normally soil with a pH of about 5.5.
Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically 0.2â10 cm (0.1â3.9 in) tall, though some species are much larger. Dawsonia, the tallest moss in the world, can grow to 50 cm (20 in) in height. Mosses are commonly confused with lichens, hornworts, and liverworts. Lichens may superficially look like mosses, and have common names that include the word moss (e.g., reindeer moss or iceland moss), but are not related to mosses.
