Which of the following investigations would shed the most light on the future distribution of organisms in temperate regions that are faced with climate change?

#Unit 9. Diversity of Life Forms
  1. Remove, to the mineral soil, all of the organisms from an experimental plot, and monitor the colonization of the area over time in terms of both species diversity and abundance.

  2. Look at the climatic changes that occurred since the last ice age and how species redistributed as glaciers melted, then make predictions on future distribution in species based on past trends.

  3. Compare and contrast the flora and fauna of warm/cold/dry/wet climates to shed light on how they evolved to be suited to their present-day environment.

  4. Quantify the impact of man's activities on present-day populations of threatened and endangered species to assess the rate of extirpation and extinction.

There were four rules of parity given by Erwin Chargaff 
1) Base A in one strand of the duplex is matched by (T) in the other strand, and base G in one strand of the duplex is matched by a complementary base (C) in the other strand
2) equal amounts of A and T, and equal amounts of C and G, in each single strand of the duplex. 
3) Purines in non-template strand applies more closely to Exons
4) GC content tends to be greater in exons than in introns
