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
Complete question:
The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K
Answer:
TRUE
Explanation:
The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.
Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.
Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.
K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.
Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.
Breakdown of carbohydrates begins in mouth with the help of enzyme salivary amylase.
D. Lysogenic cycle. In this cycle, viral DNA is inserted into the host cell's DNA. It divides with mitosis, soon creating many infected host cells. Once the lytic cycle is triggered (usually from external factors), the viral DNA is transcribed/translated into viruses.
