Stephan’s mother is a mineralogist, and sometimes she brings home samples to study. Stephan observesand compares these minerals. He knows minerals form in several ways. He is especially interested in the minerals that form from volcanic activity and the kinds of crystals they form. What determines crystal size in minerals formed by lava or magma? A. the kind of mineral that formed
B. the amount of material available
C. the rate at which the minerals cooled
D. the materials in the lava or magma

the answer to your question is b

i dont know it at allnow im just getting points at this pint

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
