One species of plant produces flowers when nights are 10 hours long. a related species comes into flower when nights are 9 hours long. what type of reproductive isolation would include this example?

Temporal isolation is the type of reproductive isolation that would include this example.

Temporal isolation is a type of reproductive barrier in which two closely related species (plants or animals) are prevented from mating and producing sterile hybrids because of their different breeding time. The difference in the breeding time may be year, season (such as fall or winter) or by time of day (daytime or at night).

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

helicase, i think thats it
