Scientific investigations often lead to the formulation of new scientific questions. the observations charles darwin made during his time aboard the h. m.s. beagle prompted him to ask which question?

Are organisms able to evolve?

Explanation:

At the time, species were considered to be fixed. Change in species, especially change from one species into another was not considered possible. However, his observations made Darwin question this, because he observed species that were unique in isolated islands, that were related to other, common species present on the continent. His conclusion was that isolation had brought species from the continent to change into new species when they had to adapt to the new conditions on the islands.

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.
