Despite inhabiting overlapping ranges, the western spotted skunk and the eastern spotted skunk do not interbreed, partly because the western species breeds in early fall and the eastern species breeds in late winter to early spring. this is an example of isolation.
a. chemical
b. gametic
c. post-zygotic
d. temporal
e. mechanical

D. temporal

Explanation:

Temporal isolation is a reproductive barrier that occurs when two similar members of a biological population occupying the same habitat breed at different times of the day or at different seasons. When this occurs, the two similar members would be unable to mate with each other. Over time, both individuals become entirely two different species through this evolutionary mechanism

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
