QUES: Secretory diarrhea means that there is an increase in the active secretion, or there is an inhibition of absorption. There is little to no structural damage. The most common cause of this type of diarrhea is a cholera toxin that stimulates the secretion of anions, especially chloride ions. Therefore, to maintain a charge balance in the lumen, sodium is carried with it, along with water. In this type of diarrhea intestinal fluid secretion is isotonic with plasma even during fasting. It continues even when there is no oral food intake.
What is secretory diarrhea?

ANS: an increase in the active secretion, or there is an inhibition of absorption

QUES: BJTs have three terminals, corresponding to the three layers of semiconductor—an emitter, a base, and a collector. They are useful in amplifiers because the currents at the emitter and collector are controllable by a relatively small base current. In an n–p–n transistor operating in the active region, the emitter–base junction is forward biased (electrons and holes recombine at the junction), and electrons are injected into the base region. Because the base is narrow, most of these electrons will diffuse into the reverse-biased (electrons and holes are formed at, and move away from the junction) base–collector junction and be swept into the collector; perhaps one-hundredth of the electrons will recombine in the base, which is the dominant mechanism in the base current. By controlling the number of electrons that can leave the base, the number of electrons entering the collector can be controlled. Collector current is approximately β (common-emitter current gain) times the base current. It is typically greater than 100 for small-signal transistors but can be smaller in transistors designed for high-power applications.
Where are BJT amplifiers most commonly used?

ANS: unanswerable

QUES: Masonic lodges existed in Iraq as early as 1917, when the first lodge under the United Grand Lodge of England (UGLE) was opened. Nine lodges under UGLE existed by the 1950s, and a Scottish lodge was formed in 1923. However, the position changed following the revolution, and all lodges were forced to close in 1965. This position was later reinforced under Saddam Hussein; the death penalty was "prescribed" for those who "promote or acclaim Zionist principles, including freemasonry, or who associate [themselves] with Zionist organisations."
When was a Scottish Lodge formed in Iraq?

ANS: 1923

QUES: The elevator motor was located at the top of the shaft or beside the bottom of the shaft. Pushing the handle forward would cause the cab to rise; backwards would make it sink. The harder the pressure, the faster the elevator would move. The handle also served as a dead man switch: if the operator let go of the handle, it would return to its upright position, causing the elevator cab to stop. In time, safety interlocks would ensure that the inner and outer doors were closed before the elevator was allowed to move.
Eventually safety locks were used to guarantee what?

ANS:
that the inner and outer doors were closed before the elevator was allowed to move
