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.

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.

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.

Describe the natural environment of the species in terms of abiotic and biotic factors,
Answer:
Abiotic and biotic factors make up an ecosystem. Abiotic factors are the non-living parts of an environment. These include things such as sunlight, temperature, wind, water, soil and naturally occurring events such as storms, fires and volcanic eruptions. Biotic factors are the living parts of an environment, such as plants, animals and micro-organisms.
Together, they are the biological factors that determine a species' success. Each of these factors impacts others, and a mix of both is necessary for an ecosystem to survive.
