One way in which the study of populations ( human populations - I assume) affects us is that they can help predict the population size in the future and prepare us for it. For example, if we see that the population is decreasing, a country might want to consider supporting child-bearing or immigration to avoid the problem of too many people receiving pensions but not paying taxes.
Answer: Affected regions may not have the political will or financial means to address environmental problems.
Explanation:
The spread of diseases due to contaminated land, water, soil and the overall environment cannot be prevented due to lack of political will and lack of financial will. As a good influence of the political party is necessary to clean up the environment, preventing pollution and contamination.
The financial means aids in diagnosis and treatment of environment related diseases and disorders. But in the absence of these aids the spread of diseases and related disorders will increase and such problems cannot be resolved. People cannot afford suitable treatment for their problems.
The actual distance will be 12 km.
<u>Explanation</u>:
The scale of the map is 1:250000
1 cm in the map represents 250000 cm.
250000cm=2500 m=2.5 km
the measurement in the map is 4.8 cm
since 1 cm represents 250000 cm or 2.5 km
The actual distance represented by 4.8 cm on the map = 4.8*250000 cm =1,200,000 cm=12000 m=12 km
