A student collects several plants and pebbles from a riverbank, places them in an aquarium, and records observations for 15 days. The sizes of the plants increase, while the sizes of the pebbles remain the same. The student classifies the pebbles as nonliving things
Which criteria does the student use as the basis for the dassification?
O ability to grow
O ability to move
O ability to reproduce
ability to respond to stimuli

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.
