The rule of 70 is a technique used to forecast how many years would take to a variable to double its value. It consists on dividing number 70 by the growth rate of the variable of interest, which in this case is the GDP of countries A and B.
According to the rule of 70, let's compute how long will take for the GDP of each country to double:
- Country A: 70/2.8= 25 years
- Country B: 70/1.4= 50 years
As the growth rates are constant, it is possible to compute the exact value of the GDP of each country in 100 years time using the number of years for output duplication.
- Country A duplicates its growth every 25 years. Hence, it will happen 4 times in 100 years. In year 25, the output will be $100,000. In year 50, it will duplicate again and reach $200,000. The third duplicate will take place in year 75 and GDP will sum $400,000. Finally, in year 100 it will duplicate one last time and country A will end up the century with a GDP per capita of $800,000.
- Country B duplicates its growth every 50 years. Therefore, it will happen twice in 100 years. In year 50, the output will be $100,000. In year 100, the last duplicate will take place, and country B will end up with a GDP per capita of $200,000.

Interactions between organisms and their environment impact the organism’s overall population is explained below in details.
Explanation:
Adaptation principle
In the evolutionary approach, adaptation is the natural mechanism by which organisms adapt to new surroundings or variations in their prevailing environment. The concept of natural choice is that characteristics that can be transferred and enable organisms to accommodate the climate better than other organisms of the same species.
1. Many sacrifices will be made as it will be necessary for me to stay away from my family and friends, which may be a little lonely for the duration of the research. It may also be necessary for me to live in a place that is not very comfortable and has fewer resources that I am used to. It may be that the place where the research will be carried out has a very different geography and climate from the place where I live, which may generate even more discomforts for me, such as very high or very low temperatures.
2. Ideally, I should take few personal belongings, so I don't have to spend a lot of time managing them and focus my time on doing the research. However, my management must be around the most necessary personal items, which I could not live without.
3. This will depend on the research and what it is evaluating, but I can guarantee that computers and organizational systems will be needed through spreadsheets and software that remain the tabulation of the collected data, their storage and optimization.
