The Linnaean system added more stories onto hierarchy the of complicatedness that Aristotle developed.

The Linnaean system of type of taxonomy was developed by Swedish naturalist named Carolus Linnaeus in the mid 1700. He created a way to organize and name species. He based his type on physical traits of organisms and uses binomial nomenclature to identify organisms. The seven main level of classification are kingdom, phylum, class, order, family, genus and species.

<h3>Why is the Linnaean system important?</h3>

The Linnaean system is critical because it led to the use of binomial nomenclature to recognize each species. Once the system was assumed, scientists could communicate without the use of deceiving common names. A human being became a partner of Homo sapiens, no matter what terminology a person spoke.

blondinia [14]
The answer is LDL (Low Density Lipoprotein)

Arteriosclerosis is the build up of cholesrol on the inner walls of the arteries. In the long run, arteriosclerosis reduces the diameter of the blood vessels, causing high blood pressure. 
The endothelial cells of arteries have receptors that facilitate binding and transportation of the LDL hence facilitation of their accumulation in the blood vessels.

Any time a scientific theory is challenged, it means it's not a good theory.Do you agree with this statement? Explain
vfiekz [6]
False. Any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement.
