The correct answer is B. An ecosystem resource; an ecosystem service
Explanation:
In ecosystems, a resource refers to any substance, material, object, etc. that is necessary for the biological processes of organisms, for example, breathing, growth, reproduction or nutrition. In this way, water is an example of an ecosystem resource because this natural resource is necessary for the life of almost all organisms. On the other hand, an ecosystem service refers to natural processes and systems that benefit humans, in the case of water cycle this is an example of an ecosystem service because due to this, humans get potable water to drink, water for growing plants and animals, among others.
Answer:
Neither country wanted to engage in a nuclear war that would lead to worldwide destruction.
Explanation:
The US and USSR became arch enemies soon after World War II ended, and that continued to be the case until the USSR seized to exist. The two countries became opponents and developed very bad and tense relations because they had different ideas as to how the world should shape up, but also because both of them wanted to be the only dominant power in the world.
Both countries were heavily armed and the weaponry was constantly icnreasing, with newer and better weapons constantly been created to gain an advantage. Nuclear weapons were abundant at both as well, but they never got used in an open war between them. The reason was simple, if a direct war between them occurred, there would have been worldwide destruction and everyone will lose, so that was kept as the last option in case of an attack by the other. Not to be mistaken though, these two were constantly in war with each other, not just diplomatic, but also military one, just that they used other countries as battlefields where they supported a particular side.
Simplifying 4m + 9 + 5m + -12 = 42 Reorder the terms: 9 + -12 + 4m + 5m = 42 Combine like terms: 9 + -12 = -3 -3 + 4m + 5m = 42 Combine like terms: 4m + 5m = 9m -3 + 9m = 42 Solving -3 + 9m = 42 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 9m = 42 + 3 Combine like terms: -3 + 3 = 0 0 + 9m = 42 + 3 9m = 42 + 3 Combine like terms: 42 + 3 = 45 9m = 45 Divide each side by '9'. m = 5
Answer: Development
Explanation: The human and natural resources in a developed area or country are brought to their full potential and to the benefit of the people who are citizens or residents there.
Development can be measured economically by the Gross Domestic Product GDP and by its effect on people through the Human Development Index HDI. While GDP measures the total goods and services produced, the HDI measures the level of education and opportunities available to people in the area or country.
