**What This Document Is**
This is a completed lab report for Activity 1 of Exercise 3 in a Human Physiology Lab (BIOL 240) at Indiana University of Pennsylvania. The activity focuses on the resting membrane potential of neurons, utilizing the PhysioEx software for experimentation. It details a student’s responses to pre-lab questions, predictions, and stop-and-think questions, alongside recorded experimental data.
**Why This Document Matters**
This document is valuable for students currently enrolled in BIOL 240, or similar physiology courses, who are completing the same PhysioEx exercise. It serves as an example of a completed assignment, offering insight into expected responses and data interpretation. It’s particularly useful for checking understanding *after* attempting the exercise independently.
**Common Limitations or Challenges**
This report represents *one* student’s work and approach. Relying solely on this example will not guarantee success, as individual results in the PhysioEx simulation can vary. It does not provide instruction on *how* to perform the experiment or interpret physiological concepts.
**What This Document Provides**
The full document includes: pre-lab quiz scores and answers (with correct answers indicated), predictions about the resting membrane potential under altered conditions, answers to stop-and-think questions related to ion movement and channel states, and experimental data including graphs of membrane potential changes over time under control and altered potassium concentrations. This preview only shows a portion of the data and questions. The complete report does *not* include detailed explanations of the underlying physiology.
