The diagrams shown represent an investigation concerning the growth of bean plants. The roots of three identical bean plants were each placed through a hole in covered tubes containing water as shown in the diagrams. Nothing was done to plant A. Vaseline was used to cover the upper surface of the leaves of plant B. Vaseline was used to cover the lower surface of plant C. The water level of each tube was marked and the plants were placed together near a window. After 24 hours, I the water level in each tube was measured. Naisoline Vasoline water lavol- A B с Which tube represents the control for this investigation? A. b. c.​

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

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.
