Which is not an example of matter and energy cycling through living things? a. trees growing b. plants absorbing carbon dioxide? c. salmon eating shrimp. d. a drop of water falling through the sky?

The answer is D. In this case, there is no cycling of energy or matter. In the choice A, water and nutrients are absorbed from the soil to make up the tree. In choice B, the carbon dioxide from the atmosphere is used to make carbohydrate in the tree. In choice C, part of the biomass of the shrimp is converted into biomass and energy of the salmon.

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.
