Document Summary

The main difference between a cell that responds to a signal and the one that does not is the. The signals that bind to receptors of the same cell that made them are known as. Which of the following includes all the others: osmosis, diffusion of a solute across a membrane, facilitated diffusion, passive transport immersed in a beaker containing a different solution. Initially, the solution outside the cell is____ to the cell: hypotonic, hypertonic, isotonic. An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane is. A deer smells a predator as it passes by and quickly bounds to safety. You view an animal cell through a microscope and observe dense, duplicated chromosomes. ______is the region on a duplicated chromosome that holds the sister chromatids together? scattered throughout the cell. A researcher treats cells with a chemical that prevents dna synthesis from starting. This drugs inhibits the cell cycle at the end of: g1, g2.
