This question is in the context of country. Self sufficiency in this regard means that a country is sufficient for itself, which is not logically and practically possible. As it is a universal fact that countries need each other to have them in their bad times and to support them when needed and also they need them to make the wheel of economy move. Because there are many products that a country may not be able to produce, so they ask the other countries to sell them the product to them, the most common example is oil, which is not found in all countries of the world. So many countries buy oil from the big oil producing countries.
Self sufficiency also creates boredom or ignorance which is true and can be avoided by specialization and trade. Specialization and trade means that a country trade in those product in which it is specialized and sell them to other countries. In this way the boredom is also avoided and the specialized skills of the people of the country are also enhanced.
nutrients is the correct answer.
Explanation:Nutrients are the compounds present in the food that is very essential to survive, grow, reproduce, to keep the immune system strong, and for the proper functioning of health.Nutrients provide energy to our body that helps to regulate and control the chemical processes.Carbohydrates, proteins, minerals, lipids, water, and lipids are the six main nutrients.
Role of soil in agriculture and its formation process.
Soil is usually the upper layer of Earth in which the growth of most plants takes place. Soil is characterized as a ‘hot bed’ which is a mixture of minerals, air, water, insects, worms, and billions of bacteria.
Soil is the most important aspect of agriculture and also the main source of nutrients needed for the growth of plants which feed us. It takes approximately 500 years to generate 2.5 centimeters of soil in a dried up or parched area.
total number of 5 earth would needed to survive.
Each person's ecological footprint in the United States is approximately 10 hectares.The Earth currently has efficient land and water of 11.4 billion hectares.
If the consumption of every people living in the world have same as average american then total number of five earth would need to survive and it is based on ecological footprint analysis.

- Lots of food
Hope this helped!
answer: - b cells
explanation: -there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.
so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
