Bryophytes are also called pioneer plants.
Depends on what mountain you are on
If you are on Everest, then the amount of effective oxygen available would be 6.9% (0 altitude would be 20.9)
that is why anyone should always bring oxygen tanks when climbing a high mountain
Answer:
<em>Pyroclastic flow.</em>
Explanation:
<em>A pyroclastic flow is a fast-moving current of hot gas and volcanic matter that moves away from a volcano about 100 km/h on average but is capable of reaching speeds up to 700 km/h.</em>
The answer is (b.) Fine Pebbles have a higher threshold velocity than sand.
Given the fact that fine pebbles' diameter size are usually 2.0 to 5.0 mm which is bigger compared to sands which diameter is usually measure only at 0.05 to 2.0 mm, thus fine pebbles have higher threshold velocity than sand. In Geophysics, threshold velocity refers to the minimum velocity of a particle such as pebbles and sand to move by the cause of wind or water. Therefore, the higher threshold velocity is the fine pebble since it is bigger.
1) Golgi ... think about the Golgi as the UPS of a cell
