I WILL GIVE BRAINLIEST Which statement best describes why radioactive atoms can be used to date
materials?

A. The number of radioactive atoms in a substance increases over
many years.
B. The ratio of radioactive atoms to other kinds of atoms changes
over time.
C. Nonradioactive atoms in rocks eventually turn into radioactive
atoms.
D. The Sun interacting with atoms in a rock causes new atoms to
form over time.

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.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
