Underground mining removes minerals from deep in the earth. Miners use blasting to separate the "waste" from the mineral deposit. Which statement best describes
an environmental consequence of this process?
O Underground mining activities often cause noise pollution
O Acid mine drainage kills plants and animals around the mine.
O High salinity of wastewater reduces soil fertility and vegetation
O Soil is removed by the force and pressure of the drilling process.
Answer:
Acid mine drainage kills plants and animals
Explanation:
took the quiz :)
The correct answer as to the environmental consequence of using blasting to separate wastes from mineral deposit is noise pollution. The statement that best describe the process, therefore, would be that underground mining activities often cause noise pollution.
Blasting simply means to break something apart or to blow up something. When blasting is associated with mining, it usually involves the use of explosives. These explosives make loud noise when they are used in blasting.
Hence, blasting can be said to be a source of noise pollution to those staying close to the mining area.

A placebo is a fake treatment that mimics the experience of the experimental group.
true
false
Answer:
true
Explanation:
Doctors (or scientists) usually use this to make sure people aren't lying about the experience.
For example, some people might expect that if they take ibuprofen or Tylenol, they won't feel as much pain, so they might make themselves believe that they aren't feeling said pain. If you use a placebo group, you are less likely to have situations like that occur, and so your data becomes more accurate.

Which explains why secondary succession generally occurs more rapidly in an area than does primary succession?
A) Average precipitation is higher
B) Moderate climatic conditions exist
C) Pioneer species are microscopic
D) Soil formation has already occurred
Answer:
Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

Which would be considered a reliable source?(1 point)
an opinion column in your favorite magazine
an article from a scientific journal
a blog written by an anonymous author
a biology textbook from 1920
When looking for updated and reliable information, you always need to point to scientific journals, magazines, encyclopedias, or textbooks recently printed or published. In the exposed example, the most reliable source is an article from a scientific journal.
----------------------------------------
When looking for updated and reliable information, you need to be careful with the source, authors, and publishment dates.
In general, scientific journals, magazines, encyclopedias, or textbooks are sources of reliable information. The material exposed on these sources has been previously checked and evaluated by a group of people trained and capable to do so. If your favorite magazine is not a scientific one, you should look for another source.
You also want to consider the authors. Some researchers are very well known, and their publications probably reflect years of investigation. By looking for these authors´ publications you will ensure a good source. You should use a blog written by a well-known author, but not a blog that is written by an anonymous one.
You also need to consider that your source should be recently printed or published. Science is very dynamic and continuously changes. Discoveries always replace old information. So when looking for a reliable source, you need to look for recent publications. A biology textbook from 1990, although it is a reliable source, it probably has old information.

25. How do the excretory systems of animals that secrete uric acid differ from those of animals that excrete urine?
34. Explain why maintaining water balance is part of the process of excreting nitrogenous wastes.
thanks!!
Answer:
25.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.
34.The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. In providing these functions, excretion contributes to the body's homeostasis, the maintenance of constancy of the internal environment. When cells break down proteins, they produce nitrogenous wastes, such as urea

Nitrogen fixing bacteria living in the roots of legumes to absorb sugars from them is an example of:
A. Commensalism
B. Predation
C. Parasitism
D. Mutualism
Nitrogen-fixing bacteria living in the roots of legumes to absorb sugars from them is an example of mutualism. The correct option is D.
What is mutualism?Mutualism is an interaction between two organisms, in which both organism live together and help each other. In an ecosystem, different organisms live together as they affect the life of each other.
Nitrogen-fixing bacteria are the bacteria that are present in the roots of legume plants, like cereal plants. They convert the nitrogen of the environment into nitrate in the soils.
So, living in the roots of the legume plants, they get nutrition from the roots, and they give atmospheric nitrogen to the soil, which increases the nutrition of the soil and the plants.
Thus, the correct option is D. Mutualism.
