The answer is watershed.
sorry if I'm wrong.
Ionic bonds form always form between a metal and a nonmetal, so the answer is D, Magnesium and Bromine.
Sodium is a metal, so a bond between two Sodium atoms will not be ionic.
Fluorine is a non-metal, so a bond between two will be covalent bond instead of an Ionic.
Magnesium and Lithium are both metals, so a bond will not be ionic.
On the other hand, Magnesium is a metal and Bromine is a non-metal, so a bond between them will be ionic.
Answer:
C. The high-tide zone is outside the range of tolerance for Semibalanus.
Explanation:
Semibalanus can out-compete Chthamalus by crowding or smothering, but Chthamalus can occupy higher tide levels than Semibalanus because it is more resistant to desiccation.
The fundamental niche of Chthamalus includes both the upper and middle intertidal zones. - The realized niche of a species is a subset of the fundamental niche, limited by biotic interactions such as competition. The realized niche of Chthamalus is the upper intertidal zone only.
False, a mutation can be the exact same
