Answer: Point mutation is easily reversible, thus non-lethal
Explanation:
Point mutation is caused by exchange of a single nucleotide for another. These change is called
1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)
2) Transversion (when a purine base substitute a pyrimidine base).
However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate

A, as with all organisms, growth is always the primary result of cell division, the mitosis type, meiosis cell division results in gametes (sperm and eggs)
In black bread mold spores are produced in structures called Sporangia. Black bread mold are fungus that reproduces in the same way like most molds. The molds make spores inside a sporangium and when the spores are ready to leave and spread more mold, the sporangium breaks open and lets the spores out.
