The study of animals' structures, behaviors, functions, and evolution is called ethology zoology biology physiology

The correct answer is zoology.

Explanation:

zoology is the branch of biology in which one study the behaviors, structures, evolution and functions of the animals. It is also known as animal science. In Animal science, you study all the aspects of animals from its evolution to the structures to the structural and functional unit of the cell.

This discipline can include animal anatomy, biochemistry, physiology, genetics, evolution, ecology, behavior, evolution, and conservation.

Thus, the correct answer is zoology.

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.
