It is called centrally-planned economy or command economy
Answer:
(a) (i) Define the term "Green Revolution" as used during the period 1945 to 1985.
- The use of modern agricultural techniques became widespread around many regions in the world. This led to higher yields through the use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.
(ii) Explain the principal agricultural practices/technologies associated with the green revolution.
- extensive use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.
(iii) Name TWO regions, in different parts of the world, where the green revolution has had a significant impact on crop yields.
- In North America, Mexican food production increased and they stopped importing food. Although currently that has reversed, and it is importing even more food than before.
- In Brazil, agricultural production increased dramatically. Both total farmed area and yields have continued to increase in the past years becoming a threat to the amazon basin.
(b) Identify and discuss TWO social, political, or cultural conditions necessary for the success of the agricultural practices/technologies of the green revolution.
- Emigration from rural areas to urban areas which resulted in a rapid expansion of urban centers. Since less labor was needed in farms, many people left rural areas due to lack of jobs.
- People started accepting genetically modified crops, which were not well accepted at first. A lot of money was invested in research and development of new seeds, fertilizers and pesticides.
(c) Identify and discuss TWO significant economic or ecological factors that may limit the long-term success of the agricultural practices/technologies of the green revolution.
- Many new agricultural techniques have resulted in a decrease of soil fertility. In many places crops cannot grow unless a lot of fertilizer is used.
- Countries were the green revolution was originally successful, like Mexico (where it started), have reduced the total area dedicated to crops. As the yields increased, the price of food started to decrease and many small farms could not keep operating.
Answer:
in folklore, a narrative containing information about actual persons and events. Originating from the tales of eyewitnesses, the traditional account departs from its original factual basis when retold and becomes subject to free poetic interpretation.

The retention and excretion of excess water and ions are performed by the kidneys, which is a part of the excretory system.
Answer:
Because there are other factors that influence the weakening or strengthening of the dollar, not just the dollar exchange rate in relation to the exchange rates of other countries' currencies.
Explanation:
Although the United States has registered increases in the trade deficit, that is, when the country imports more goods and services from abroad than it exports, there are other factors that determine whether the country's currency is valued or not. In the case of the dollar, its value has not decreased despite the fall in the exchange rate of the dollar in relation to the currencies of its main trading partners due to the fact that the dollar is the main reserve currency in the world, which means that the dollar is the fashion of commercial transaction in the world, therefore its value is not lost in relation to other currencies, since several important transactions in the world such as gold and oil commodities are traded in dollars.
There is also the fact that the US attracts a lot of international investment for US Treasury bills, which helps to strengthen the dollar.
