Which option correctly identified the two main ways that minerals are classified
a. rarity and use
b. country of origin and use
c. crystal structure and chemical composition
d. use and chemical composition

I think the answer would be C. crystal structure and chemical composition, this is because crystal structure helps determain by the human eye what the mineral would be classisfied as. The chemical build up or composition helps indefenitly by breaking down the minerals make up. The answer is NOT D. use and chemical coposition. Use is absured, who who look at a mineral and say the use is... when they don't know what the mineral is yet. Use does not specify the mineral! (Sorry for my spelling) Hello there! If this answer was the most helpful one, brainliest it, rate, and thank! If it was somewhat good at least rate and thank me :) . Comments are always appreciated! ~Summer

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
