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.
Crenation is a phenomenon which occurs when cells of animal origin are exposed to a hypertonic solution, meaning that the solution which bathes the cells has a high concentration of solutes.In crenation, the cells shrink and their shapes become distorted, often with a ruffled or scalloped edge.The change in cell shape can be seen in microscopy of the cells, and can be a sign that someone is experiencing a medical problem. These cells may die as a result of impairments in cell function.n crenation, the cells shrink and their shapes become distorted, often with a ruffled or scalloped edge.
