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
Answer:
The correct answer is option b. "by their dominant processes that formed them".
Explanation:
Mountains are classified in four different types according to the dominant processes that formed them. The four different types of mountains are: upwarped mountains, fault-block mountains, folded mountains and volcanic mountains. Upwarped mountains are produced by a differential of pressure from inside the Earth that pushed the crust upwards. Fault-block mountains were formed by tectonic plate movement, folded mountain when two plates move together, while volcanic mountains are formed by a crack in the Earth known as volcanic vent.
Explanation:
in binary fission one amoeba cell divide into two daughter cell which are genetically identical
first the nucleus divide into two then the cytoplasm divide and two new daughter cells are formed
