Statement \(I\) : Mature \(\beta\)-cells synthesis various types of antibodies which are displayed on their membranes. Statement II : Antigenic site binds to an antibody is called epitope
1 Both statement I and statement II are true
2 Both statement I and statement II are false
3 Statement I is true but statement II is false
4 Statement I is false but statement II is true
Explanation:
: Mature \(\beta\)-cells can synthesize and display membrane-bound Ig, which is distinct from other lymphocytes. Each mature B-cell clone only secretes one of antibody, which can bind a specific antigen. The small site on antigen to which a complementary antibody may specifically bind is called an epitopes or antigenic determinant. Both Statement I and Statement II are true.

In fluid mosaic model of plasma membrane
1 Upper layer is non-polar and hydrophilic
2 Polar layer is hydrophobic
3 Phospholipids form a bimolecular layer in middle part
4 Proteins form a middle layer
Explanation:
C Fluid mosaic model of the plasma membrane was proposed by S. J. singer and Garth L. Nicolson . According to this model, the plasma membrane is a phospholipid bilayer in which the proteins cholestrol and carbohydrates are integrated which give it a mosaic like appearance. In Phospholipids layer upper or outer part like hydrophilic and polar heads of the lipid molecules and inner side of the bilayer hydrophobic \& non-polar tails are present.

The microscope usually used for seeing living cells or tissues is
1 compound microscope
2 electron microscope
3 phase contrast microscope
4 light microscope
Explanation:
C Phase contrast microscope is used to study dynamic aspects of cells as the cells are living. - Phase contrast microscopy is based on the principle that small changes in the phase can be transformed into changes in brightness of that object. - Compound microscope is used for viewing samples at high magnification (40-1000). It contains two types of lenses that function of magnify an object - Electron microscope used in biomedical research to investigate the detailed structure of tissues and cells organelles and macromolecular complexes. - Light microscope are used to view microscopic organism too small to be seen with the naked eye.
