If a mouse is given a dose of radiation sufficient to destroy its immune system, then injected with purified hematopoietic stem cells, what should happen?

A-

The mouse survives over 3 months and if successful transplantation

of their new HSCs rescues a second lethally irradiated recipient,

they can be considered to have received near pure HSC,

reconstituting their immune system.

B-

The mouse's remaining immune cells will cause a graft versus host

immune reaction, targeting the new HSCs for destruction.

C-

The new HSCs will over proliferate and the mouse will develop

leukemia.

D- the mouse dies as its immune system might attack the HSC.​

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
