The cell contains many nuclei containing DNA, so DNA synthesis and mitosis are taking place, but the cell is not undergoing cytokinesis.
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

5. Corn can be used for ethanol fuel, and a new crop of corn can be grown and harvested each year. Corn is a renewable resource. Also, renewable resources <u>cannot</u> be replaced in our lifetime.
Answer;
b. Their ability to pass on genetic information.
Explanation;
-Protobionts are systems that are considered to have possibly been the precursors to prokaryotic cells. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a membrane or a membrane-like structure.
-They exhibit some of the properties associated with life, including simple reproduction, metabolism and excitability, as well as the maintenance of an internal chemical environment different from that of their surroundings.
