B. Do faster breeds of horses have longer legs?

Explanation:

A scientific question is a question which can be answered directly by observation or applying suitable scientific experimentation procedures.

Among the options given, B. Do faster breeds of horses have longer legs? is the correct option. This can be answered scientifically by measuring the leg length and comparing it with running 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.
