Plz hurry it's urgent! which describes a process where a precipitate is formed? a. a solution of agno3 is added to a solution of cacl2 to produce solid agcl and a solution of cano3. b. propane gas combusts to form co2 and h2o. c. a solution of hcl mixes with a solution of ca(oh)2 to produce h2o and cacl2. d. a solution of h2so4 mixes with a solution of naoh to produce water and na2so4.

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.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
