The EKG is hooked up, and Mr. M's trace looks very abnormal. His heart rate is low. The T wave, which indicates repolarization of the ventricles, is unusually large and pointed and the QRS wave, which indicates the depolarization impulse’s passage through the ventricles, is widened or slowed. "That's a classic EKG for hyperkalemia (high blood potassium)!" The doctor gives Mr. M an injection of calcium gluconate. Calcium ions block the Na+ channels on nerve and muscle cells. How will this help counteract the effects of high blood K+? g

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
