Consider the following statements about biological communities.(I) Their members share a common gene pool.(II) The community remains stable even though some physical aspect of the environment may undergo change.(III) They passes predictable kinds of species of predictable proportions.(IV) Interactions between their members are more frequent within the community than between their members and those of neighboring communities.Which two of the above statements apply to all stable biological communities?
Correct answer: D. III and IV
- A. I band II
- B. II and III
- C. I band III
- D. III and IV
- E. II and IV
Explanation
A. I is not right since a community involves different populations which may have different gene pool.B. II is also not right since different populations may interact in different ways with each other and disturb the genetic pool and stability.C. III is right and is a fact.D. IV is also right since intra-specific interactions are more common than inter-specific interactions in communities.Hence III and IV are the right options (Option D).

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
