Which of the following is a major cause of the size limits for certain types of cells?
a. limitation on the strength and integrity of the plasma membrane as cell size increases
b. the difference in plasma membranes between prokaryotes and eukaryotes
c. evolutionary progression in cell size; more primitive cells have smaller sizes
d. the need for a surface\ area of sufficient area to support the cell s metabolic needs
e. rigid cell walls that limit cell size expansion

A

Explanation:

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.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
