Answer:
reflect the conditions and changes of an environment where they live.
Explanation:
Effective indicator species need distinct environmental factors to sustain and survive in the environment. They reflect the conditions and changes of an environment where they live.
Fishes, specifically steelhead trouts, are an effective indicator species because steelhead trouts require distinct environmental conditions to survive such as temperature of the water, availability of food, specific waterbed, etc. If there is an absence of steelhead trouts in a particular body of water, scientists can easily determine that the water has environmental problems.
Answer:
Liechtenstein is a nation of Central Europe, with borders with Austria and Switzerland. It is a very small nation of only 160 km2, populated by some 38,000 people who enjoy a very high standard of living.
The GDP per capita of this country is $ 98,432, being the third country with the highest GDP per capita in the world. The reasons for this great prosperity of the country are basically found in the fact that Liechtenstein has become a tax haven, with banking activity being the most important in the nation and the main employer of the country. Thus, given that many of the world's great fortunes deposit their assets in the country's banks, the fees they charge and the taxes that the government collects, albeit minimal, serve to guarantee an extremely high quality of life for its few inhabitants.

Answer: x = ³⁄₂ ± √31/2
Explanation: If you are looking to solve this, you need to use the Quadratic Formula.
In this equation, a = 1, b = -3, and c = 10.
When you solve through it, you will eventually get to the point √-31.
Since it is not possible to have a negative number inside a square root, you bring out the imaginary number, hence the √31.
The radical √31/2 does not simplify.
The final answer is x = ³⁄₂ ± √31/2
