Question

introduction of alien DNA into the host cells. 30) What is so special about tropies that might account for their greater biological diversity? (A) Unlike temperature regions subjected to frequent glaciations in the past, tropical of Intitudes have remained relatively undisturbed for millions of years and thus, had a long evolutionary time for species diversification (B) Temperate environments, unlike tropical ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to a greater species diversity (C) There is more solar energy available in the tropics, which contributes to higher productivity, this in turn might contribute indirectly to greater diversity 1A only 2) B and C 3) A and C 4) A, B and C 31) We need to realize that every species has an intrinsic value, even if it may not be of current
