   B: Sponatneous generation
   C: Biogenesis
2. A: Lamarck
   B: Special creation
   C: Inheritance of acquired characteristics
3. A: August Weismann
   B: Use and disuse
   C: Continuity of Somatoplasm
4. A: August Weismann
   B: Inheritance of acquired characteristics
   C: Continuity of Germplasm

Q.

If Darwins theory of pangenesis shows similarity with the theory of inheritance of acquired characters then what shall be correct according to it?

1. Size of organs increases with ageing
2. Development of organs is due to willpower
3. There should be some physical basis for inheritance
4. Useful organs become strong and developed while useless organs become extinct. These organs help in the struggle for survival
