Choose the ood one out and give reason-:

1) Adenine , Guanine, Uracil, Thymine,Cytosine.

2)Glycolysis,photosynthesis ,photolysis , Carbon dioxide fixation , Oxygen evolution

3)Hay,Sewage,styrofoam,paper

4)insulin, glucagon ,oxytocin, stomatostatin

5) TAB vaccine ,BCG vaccine,Salk's vaccine, Rabies vaccine.

 
1. Uracil is the odd one out here as it is present in RNA while Adenine, guanine, Cytosine and Thymine are present in DNA.
2. Glycolysis is odd one out as rest all are associated with photosynthetic processes.
3. Styrofoam should be odd one out here as it is non biodegradable made from polystyrene. Rest all are biodegradable materials.
4. Somatostatin should be odd one out as it is growth hormone inhibiting hormone whereas all others are associated directly or indirectly with various aspects of growth.
5. BCG vaccine is odd one out here as this vaccine is made from attenuated live Mycobacterium bovis. Whereas TAB vaccine is killed typhoid and paratyphoid a and b, Salk’s vaccine is dead poliovirus and rabies vaccine is also killed rabies virus.
