The high productivity of american agriculture is exemplified by
a. low crop yields per farm worker
b. high crop yields per farm worker
c. the small cultivated area per inhabitant
d. the small cultivated area per farmer

The correct option is B.

The American agriculture is highly productive and this is as a result of high crop yields per farm worker.

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.
