  • When a sea urchin egg is removed from the ocean and placed in freshwater, the egg swells and bursts. Which of these causes water to enter the egg? F Coagulation G Sodium pump H Active transport J Osmosis 34 Osmosis is the movement of water through a membrane from cleaner high concentration to less clean lower concentration.

  • 4. Histamine is a polar chemical that can lead to an allergic response when it is released by the bodys immune system. An antihistamine is a drug that can help prevent the allergic reactions associated with histamine. An antihistamine is a similar molecule to histamine in size, shape, and polarity. How does an antihistamine most likely prevent the effects of histamine? A It increases the diffusion of histamine across the membranes of target cells. B It binds to histamine receptors on the surfaces of target cells. C It causes target cells to increase production of histamine receptors. D It blocks histamine receptors found in the cytoplasm of target cells. Model histamine antihistamine Real histamine Home Back to Cell functions

  • Which would most likely cause the liquid in Tube A to rise? F Starch concentrations being equal on each side of the membrane G Water passing from a region of lower starch concentration to one of higher starch concentration H Water and starch volumes being the same J Solute in the tubes changing from a higher temperature to a lower temperature 14 Osmosis is when cleaner water (in this case distilled) wants to go through a membrane to less clean water (in this case, starchy). Tube B water goes through the Dialysis membrane toward the Tube A. Water goes from high concentration to low concentration. Or if you want to look at it from the solute point of viewthe water goes from less solute solution to more solute solution. Starch is a solute. The solute (starch) doesnt go through this membrane.
