thrust angle
The maximum length between the two transverse bulkheads is called the longitudinal centerline distance. This measurement is crucial for determining the structural integrity and stability of a vessel.
structural model of plasma membrane is called the selectively permeable membrane Structural model of the plasma membrane is called Fluid Mosaic Model.
