Carol and Sam took a package of yeast and poured it into some warm water. Yeast is something your mother or dad might use when baking bread. Yeast helps the bread to rise. After an hour, the students noticed that the yeast solution was bubbling. They used a dropper to make a microscope slide of some of the liquid containing the yeast. This is what they saw. Carol said that she thought yeast was a living thing. Sam thought she was wrong. What do you think? Explain.

D) The yeast is alive. It has cell structure.

Explanation:

I took this on usatestprep.

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.

is in the form atp or adenosine triphosphate
