Why do scientists prefer to have more than one theory about something

Biology
1 answer:
Advocard [28]3 years ago
7 0

Having one theory is setting a limit on your potential and the potential of the overall theory and subject you are working on. Having multiple theories gives you a broader idea and perspective of what is going on, and even though one may slightly contradict the other, it is okay because that is what theories are for.

To the point, scientists usually have more than one theory so that they can gain a broader perspective on the matter and maybe even increase the chance of being correct on the matter.


Hope this was helpful.

Cheers,

Refer to the paragraph about the formation of the isthmus of panama. the sister populations on opposite sides of the isthmus are
Dimas [21]
The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.

What does this article reveal about the role Black inventors have played in America's history? Explain your answer.
cupoosta [38]

Answer:

The article revealed the fact that Black inventors have always played an active role in inventing new things in America. In the 18th and 19th centuries they were denied the right to patent their inventions because of their status as slaves. This has changed for the better in present times as many Black inventors are being granted patent rights.

Explanation:

The article, "America’s always had black inventors – even when the patent system explicitly excluded them", by Shontavia Johnson, explained the active role that Black Americans, both free and slaves played in inventing things in the United Slaves. The article explained that although the patent rights signed into the constitution in 1787 was written in a neutral tone, it did not change the fact that black inventors were actually denied patent rights.

This segregation affected people like Henry Boyd, Ned, Benjamin Montgomery among others. In recent times, this segregation has significantly been curbed as many Black inventors are now owners of patents. An example is Lonnie Johnson, inventor of the Water Gun and owner of more than 80 patents.
