The magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth's outer core driven by heat escaping from the core, a natural process called a geodynamo.
Explanation:
A single nucleotide-pair substitution missense mutation causes a change of a single amino acid into another. Aa a result, the produced protein will have an almost normal sequence except for one amino acid.
On the other hand, a frameshift mutation changes the Open Reading Frame (ORF) of the ribosome. The ribosome moves along the mRNA every three nucleotides (codons) and translates them into amino acids that will form the nascent protein. If there is a frameshift mutation (an insertion or deletion of a number of nucleotides not multiple of three) the ribosome will "read" the mRNA differently and will identify different codons than the wild-type sequence, so a large number of amino acids will be different in the mutated protein.
A. Species adapt over time based on the environmental selection pressures. Individuals cannot go through evolution, since evolution consists of natural selection, which chooses for individuals with certain advantageous characteristics to survive, and for the individuals with disadvantageous characteristics to die. The favourable allele coding for the advantageous characteristic in individuals will then be passed on to their offspring, and natural selection continues.
Hope this helps! :)

Answer:
probably natural selection but it could also be discontinous variation.
Explanation:
depends on what context is??
