Answer: 2. The plants and animals diffused to a region with climate and geography similar to that of their point of domestication.
Explanation:
Knowledge of the centres of origin of plants and animals has increasingly improved. it is much harder to identify the way through which plants and animals were distributed, by what roads and what means they arrived at one place or another, who brought them and who diffused them.
One very important note is that plants and animals diffused to a region with climate and geography similar to that of their point of domestication which makes them survive and develop to the stage of harvest.

Explanation:
The effects on health of transport-related air pollution are among the leading concerns
about transport. Research in recent decades consistently indicates the adverse effects
of outdoor air pollution on human health, and the evidence points to air pollution
stemming from transport as an important contributor to these effects.
This book provides a systematic review of the literature on transport-related air
pollution and a comprehensive evaluation of the health hazards of such pollution. It
focuses on air pollution related to road transport (mostly from urban and suburban
passenger and freight transport) and the risks it presents to human health. It also
considers the entire chain of relevant issues: from patterns and trends in activities that
determine the intensity of emissions from transport, to primary emissions and the
formation of secondary pollutants by means of transportation, and fi nally through to
patterns of human exposure to such pollutants. The discussion of the adverse effects on
health considers the results of both epidemiological studies and toxicological assessments
of biological mechanisms.
Answer:
The Great Plains undergo changes from one year to another. These changes are determined by the production of floods, the accumulation of sediments or changes made by man (dams, construction of dams, gravel pits).
The Rocky Mountains shrunk annually. External factors (water, air, wind, freeze-thaw process) cause changes in the structure of the rocks and so there are changes in the mountain landscape.
