<h2>Membrane potential </h2>
Explanation:
- Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)
- In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential
- Resting membrane potential of excitable cells is established by Na+ and K+pump
- Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels
- Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
- Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
- Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
Interviews:
- Objective: purpose is to obtain Information
- Minimal legal requirements; no rights warnings
- cooperative relationship between interviewer and subject likely
- no guilt
- moderate planning
- Most Important: private and semiprivate; distraction could cause witness to forget key info
- Interrogations
- Objective: purpose is to test information already obtained, obtain valuable facts; eliminate the innocent; identify the guilty; obtain a confession
- extensive pre interrogation legal requirements; rights required
- hostile relationship likely
- guilt suggested
- extensive planning
- absolute privacy
I think it’s option B
I hope it helps you
