Answer:Atoms of nonmetals have a tendency to gain or share electrons when they react.
Explanation: Non-metals are elements that gain electron to form negatively charged ions known as anions.
When non-metals react, they either gain/accept electron from a metal atom or share electron with another non-metal atom. When a non-metal accepts an electron from a metal atom, the type of bond formed is called ionic or electrovalent bond. In electrovalent bond, the metal atom transfers its valence electrons to the non-metal atom so that both attain a stable octet or duplet structure.
When a non-metal shares electron with another non-metal atom, the type of bond formed is known as covalent bond. In covalent bond, the two non-metal atoms share a pair of electron, each atom donating one electron to form a pair.
From my speculation it is loss of habitat and global warming
I believe the correct answer among the choices presented above is option C. In the oxygen revolution, C<span>yanobacteria were the first organisms to produce oxygen in water, which then escaped into the atmosphere. They were said to be the first microbes to produce oxygen.</span>
Answer:
The correct answer is statement b.
Explanation:
This is due to the fact that the reduction of the vast majority of forest land, that is, mainly in Brazil has resulted in the extinction of the unknown and the familiar species. This has also declined the biological diversity and thus has immensely affected the fertility of the soil.
The soil has turned shallow and thus are less fertile in comparison to the Mid-Western United States. The Midwestern parts of the United States possess variety of soils, which are produced due to the glacial deposits and thus provides more fertility to the soil.
