[Solved] Marcus is excited to be working in the laboratory of Dr. Flores, an expert on electrical signaling in neurons. However, he is surprised to learn that the research is done on squid axons placed in sea water. He asks Dr. Flores the reasons for this approach. All of the following reasons are among those that Dr. Flores provides EXCEPT A) that a recording electrode can be inserted into a squid axon without disrupting its function. B) that the readings from inside the axon can be compared to the readings from the surrounding seawater. C) that squid axons are myelinated, increasing the speed of propagation of an action potential. D) that squid axons can be as great as 1 millimeter in diameter and are visible to the naked eye. Dyspnea: The experience of breathing discomfort or difficulty, often described as shortness of breath. Sinus Tachycardia: A condition where the heart rate exceeds the normal resting rate, typically defined as a heart rate greater than 100 beats per minute in adults. Electrocardiogram Monitor: A device used to record the electrical activity of the heart over a period of time, detecting cardiac abnormalities. Palpitations: The sensation of having rapid, fluttering, or pounding heartbeats.
