Changes in the dna are called mutations. They can occur spontaneously. Mutations can only be passed down in gametes--sperm and egg cells. with Darwins theory at mind a mutation needs to pass the test of natural selection to remain in the gene pool. So purposly making mutation or altercations may end in diseases/illnesses or in some cases death because they body can not take it.....hope this helps if it doesnt im sorry!
Answer:Multicellular and Eukaryotic are traits that can be true for every Kingdom past Protists on this branching tree diagram. These are the traits which were evolved that Protists just missed, plants and fungi got these traits and transferred them to their descent as well.
Explanation:
Answer: The correct answer is B) Superconductor, conductor, semiconductor, insulator.
Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.
Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.
Thus, B) is the right answer.
