In tissue from the intestinal epithelium of a frog, the following proportions of cells were found at each stage of the cell cycl
e: Stage Proportion of Cells
Interphase 0.90
Prophase 0.04
Prometaphase 0.02
Metaphase 0.01
Anaphase 0.02
Telophase 0.01
If the entire cell cycle in frog epithelium cells requires 20 hours for completion, what is the average duration of each stage?
Global warming resulting from human emissions of greenhouse gases. The consequences include habitat loss; shifts in climatic conditions and in habitats that surpass migrational capabilities; altered competitive relationships.
