The tip of a pair of scissors

1 answer:

3 0

"A pair of scissors consists of two pivoted blades. In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing<span> action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung - to increase the cutting and shearing tension only at the exact point where the blades meet. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension. An ideal example is in high-quality tailor's scissors or shears, which need to be able to perfectly cut (and not simply tear apart) delicate clothes such as chiffon and silk."</span>

The most widely accepted theory among scientists is that the last place humans migrated to was the Americas. Europe. South Asia.

adelina 88 [10]

The correct answer is - the Americas.

The Americas from what is known and discovered till now are by far the latest continents that were settled by the people. Even though it is still not clear when exactly did this happened it is in the range between 19,000 and 12,000 years ago as the biggest given and lowest given number by scientists. It is understandable though that people found it hard to migrate in this part of the world since it was cut of by an ocean and the only way that they could migrate was through the Bering Land Bridge which in fact was an icy bridge between the continents and extremely inhospitable place. There is also the large carnivores in North America as a factor that delayed the migration, and of course the ongoing ice age which covered huge portions of North America with glaciers, ice and snow.
