Arrange the following events in endochondral ossification in proper sequence:

(1)Cartilage matrix is calcified and chondrocytes die.
(2)Chondrocytes hypertrophy.
(3)Cartilage model is formed.
(4)Osteoblasts deposit bone on the surface of the calcified cartilage called the primary ossification center.
(5)Blood vessels from the periosteum invade calcified cartilage bringing in osteoblasts and osteoclasts.

The diagram illustrates the activity of vesicles during a cellular process.

Describe at least 2 abiotic and two biotic factors found in the desert biome how do these abiotic factors interact with the biotic factors

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
