Answer:
Monoclonal antibodies (mAbs) are produced by introducing an antigen to a mouse and then fusing polyclonal B cells from the mouse's spleen to myeloma cells. The resulting hybridoma cells are cultured and continue to produce antibodies to the antigen.
Explanation:
An example of a monoclonal antibody is blinatumomab (Blincyto, Amgen), used to treat certain cancer, types of acute lymphocytic leukemia.

Answer:
The correct answer is option 'e' : Cholesterol
Explanation:
The ease at which materials can be transported across a membrane depends on the membrane permeability. Membrane permeability is basically the ease at which materials are transported across membrane . As we know that upon increasing the viscosity of any fluid it's resistance to deformation increases or it applies a greater resisting force if we try to change the shape of the membrane thus reducing the permeability of the membrane. the increase in cholesterol increases the viscosity of the membrane thus reducing it's permeability.
