Eukaryotic cells originated approximately __ years ago. They differ from prokaryotic cells in that they contain a membrane-bound __ , in addition to other organelles. The nucleus is thought to have evolved due to an invagination of the __ . The __ , organelles that synthesize ATP, and the __ , organelles that synthesize glucose, are thought to have evolved from __ . The __ suggests that these __ were engulfed by another cell. However, instead of being consumed, a __ occured and they became organelles. This theory of the origin of organelles is called the __ .

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.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

if you listed your answers right then i believe your answer is b.
