Answer: polyunsaturated fatty acid residues
Explanation: Unsaturated fatty acids have a lower melting point so arctic animals have these fatty acids in their membranes.
Answer:
Cations, Oxygen, Anions, Hydrogen
Explanation:
Water molecule is polar (meaning it has dipoles). The oxygen having a higher atomic mass attracts most of the electron cloud of the molecule becoming partially negatively charged and leaving the hydrogen end to be partially positive.
An Ionic compound is one between two atoms where one donates its electrons to the other for both to achieve stable configuration. The two atoms, therefore, become charged and are bought together by electrostatic forces.
When an ionic compound is put in water, it dissociates into its ions (anions and cations) They attract and repel with the polar water molecules depending on their charges. The anions (negatively charged ion) are surrounded by water molecules with the hydrogen ends and the cations are surrounded by water molecules with the oxygen ends.
Mercury because it is way too hot to have an atmosphere.
Answer:
Mangrove forest
Explanation:
Mangrove forest exist only in high saline environment. Lake is a closed type body of water so it is expected with the least variation of salinity.
