Answer:
They found four key changes: the unprecedented homogenization of species around the world through human-instigated species invasions; the growing interaction between the biosphere - the sum of all Earth's ecosystems - and technology; the total domination of one species on land and water; and human impact on evolution
Hierarchy and there are five if them
It is the lithosphere that is broken into tectonic plates, which undergo some large-scale motions. The boundary regions between plates are aptly called “plate boundaries.” Based upon their motions concerning one another, these plate boundaries are of three kinds: divergent, convergent, and transform.
I believe the answer is False, because China developed such innovations.
Not 100% but I hope this helps ^-^
<u>Answer</u>: <em>Option (A)</em>
<em>The metallic bonding is optimal when the distances between the metal and the oxygen are the smallest.</em>
<u>Explanation:</u>
<em>Hardness increases</em> with respect to <em>shorter distances </em>between the metal and the oxygen compounds, the reason for the increase in hardness is due to metallic bonding<em> (electrostatic force between electrons and positive ions) </em>which is optimal between them.
As the <em>distance decreases, hardness increases</em> and for increasing distances hardness decreases. So when the molecular weight is large, it has smaller valence or less charge on the metal which makes the <em>bond weaker and less hard.</em>
