Ongoing studies at Mount St. Helens have added to scientific knowledge about succession. Which two statements about succession are true? During succession, the biodiversity in an area often increases over time.
During succession, the biodiversity in an area often increases over time.

The earliest stages of succession usually have the highest biodiversity.
The earliest stages of succession usually have the highest biodiversity.

Only one species at a time will colonize an area.
Only one species at a time will colonize an area.

Many species can colonize an area at the same time.
Many species can colonize an area at the same time.

Chance does not play a part in determining when species colonize an area.

explanation:

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
