Marcus is admitted to the hospital for a bone marrow stem cell transplant from his brother. what will happen after his brother’s stem cells are transplanted into marcus?

The correct option would be B. The stem cells will divide through mitosis to create diploid stem cells.

Explanation:

Mitosis can be described as a process by which all cells of the body replicate. The cell undergoing mitosis results in two diploid daughter cells.

Bone stem cell is a therapy in which stem cells from a donor are inserted into a patient so that the patient can form healthy tissues.

The stem cells, when given to a patient, will divide just like the normal cells of the body through the process of mitosis. The results will be two daughter cells having diploid chromosomes.

Once the bone marrow stem cells are transplanted into Marcus, the process of mitosis takes place in those cells and they multiply in number, hence fulfilling the purpose.

When bone marrow cells from one patient is transferred to another patient, the process of mitosis takes place in those cells and they divide into daughter cells, thus giving rise to healthy tissue in the body of the receiver.

Thanks for asking. I hope it was helpful.

Answer/Explanation:

Types of reproductive isolation include: temporal, ecological, mechanical, and behavioural.

A snail with a flat disc-like shell will not be able to mate with a snail having a conical shell - this is an example of mechanical isolation, where the animals are physically unable to mate due to incompatible body shapes and sizes.

The reproductive organs of male bush babies do not match with the reproductive organs of females of other bush baby species. - this is another example of mechanical isolation, as the sexual organs will physically not allow reproduction between these species

The mating call of a cricket is not recognized by a cricket of other species - this is an example of behavioural isolation, which results from incompatible mating rituals. I.e. the animals do not respond to each others mating behaviours

The signals sent by a male firefly are not recognized by the female firefly of other species. - this is also an example of behavioural isolation.

Temporal isolation is where species cannot interact because they do not have the same mating seasons or are not active at the same type of day. ?Ecological isolation occurs when two species do not come into physical contact to one another because they access different areas of the habitat. E.g. mating zones, food sources or nesting sites.
