Answer 1

23) The transitional epithelium is a stratified epithelium, and is made up of multiple layers. It gives the ability of an organ holding liquid to distend. Like the urinary bladder, It is hence found in the

a) Urinary system

24) The formed elements are the cells and the cell pieces in the blood. Ther erythrocytes or the red blood cells are by far the most numerous formed elements of the blood. Forming 86.6 percent by weight.

B) erythrocytes

25) Only Osteoclasts have ruffled borders and secrete HCl. This is too remodel and dissolve bone.

E) Osteoclasts

26) Condyloid joints provide side to side, up and down movement. That is movement in two planes. Hence it is a bi-axial joint. Like the wrist so the answer will be

d) A and C ( biaxial movement like the wrist joint)

27) By definition when bones have overlapping bevelled edges it is a lap suture, If it is non overlapping it is a plane suture. The teeth like interlocking is a serrate suture.

b) Overlapping bevelled edges

29) the two ways an organ can increase in size is by hypertrophy (increase cell size) and hyperplasia (increase cell number).

There fore the answer is

D) all of the above

31) Lipids are used to form the plasma membrane, cells vacoules etc and are a major source of stored energy. Both glycerol and eicosanoids are lipids .

The answer is B and C.

32) the primary structure of the protein is the sequence of amino acids called polypeptides.

Answer C)

33)Desmosome are spot adhesions which act to prevent tearing of the cell. They contain cadherin which anchor one cell to the adjacent cell.

Option) A
