Rotation is the act of raising the nose of an aircraft (by pulling back slightly on the control yoke or stick) during the take-off roll, so that it leaves the runway. Rotation allows for a precise, positive departure from the runway.
Crenation is the loss of water from an animal cell due to osmosis. Lysis is the rupture of the cell wall due to too much water moving into an animal cell due to osmosis. Both â¦crenation and lysis have drastic effects on the animal cell.
The descriptor can apply to objects of different types, including cells, where one mechanism of crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis.he descriptor can apply to objects of different types, including cells, where one mechanism of crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis.
