There are both stimulatory and inhibitory proteins that help to regulate the cell cycle. Name one stimulatory protein and one inhibitory protein. At what point in the cell cycle are these proteins active and what are their effects on the cell cycle and the fate of the cell? Im pretty sure that the stimulatory protein is cycline-dependent kinases, and the inhibitory protein is retinoblastoma proteins, but I don't know what point in the cell cycle these proteins are active and what are their effects on the cell cyle and the fate of the cell.

If someone could do the first couple, just so i can see how it's done that would be great! 20 points. complete a dichotomous key for the 10 leaves on the common leaves sheet. the chart provided here allows for 11 pairs of statements. depending on how you build your dichotomous key, you may or may not need all of them, or you may need to add some.

Ineed to get this test done which of the following statements is correct in hour our immune system responds to a potential pathogen? a.) the skin will be the first line of defense, and then the many phagocytes in the bloodstream will attempt to consume the possible pathogen. b.) b cells will start reading the antigen code immediately and call t cells to assist in destroying the pathogen. c.) the adapted immune system will call on the innate immune system to destroy the pathogen. d.) the t-cells in the adapted immune systems are the first to recognize the pathogen
