What are some of the ideas about the cause of the Cambrian Explosion? This is the answer key The Cambrian Explosion may have occurred due to a genetic revolution.
Furthermore, a rise in the oxygen levels may have allowed animals to become
larger. An additional explanation was that there was an "arms race" to evolve into
an organism that would not be eaten.

But I need someone to paraphrase it, so could someone do that for me or either go to the website where my teacher is wanting the answer from: https://flexbooks. ck12.org/cbook/ck-12-middle-school- life-science-2.0/section/4.7/primar y/lesson/microevolution-and-macroev olution-ms-ls

Plants consume most of their carbon from a. the soil b. the water c. the roots d. the air

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
