<em>The correct option is B) Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.</em>
Explanation:
Genetic continuity can be described as a fact that the daughter cells have the same amount and same type of genome as the parent cell. It includes the transfer of parental traits to children.
Binary fission can be described as a process of division which bacteria divides. Two daughter cells are produced as a result of binary fission. Each daughter cell is identical to the parent cell and hence maintains genetic continuity.

In the case of newborn twins, Brianna blood pressure is not normal but rather is low at 85/55 compared to Christophers 110/70. She has inadequate pumping of blood from her heart to the body while her breathing is rapid and deep in trying to get oxygen. It is because of inadequate pumping of blood that may lead to issues with her lungs.
Before she was diagnosed with retractile sclerosing mesenteritis, her eyes and lips were blue while her blood pressure could not read. After two weeks o her surgery, her blood pressure dropped severely low and had a breathing tube and 13 IV lines. She had caused lung damage caused by aspirations of contents in the stomach.
By third week she was in a coma but regained her physical skills and her consciousness after her last surgery (fourth).
