Answer:
Convection cells in earth's outer core
Explanation:
Earth's outer core is liquid and it has a lot of highly conductor melted iron that is flowing, making spiral roads of electric current that generates a magnetic field, that in this case works like a magnetic dipole with a north and a south pole.
The earth's magnetic field protects the earth from the solar vents.

Answer:
GUA and GUG.
Explanation:
If you look at the attached genetic code, the wild-type glutamic acid (Glu) is coded by the codons GAA and GAG.
Valine (Val) can be coded by the codons GUU, GUC, GUA or GUG.
Sickle-cell hemoglobin arises from a single mutation, which causes the translation of Val instead of Glu. The only codons that code for Valine that differ in just one base with the Glu codons are GUA and GUG.
