Answer:
Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air. ... Lift acts through the center of pressure of the object and is directed perpendicular to the flow direction.

Answer:
C) promoter; operator
Explanation:
In bacteria most structural genes are grouped under the same promoter in an arrangement known as operon. RNA Polymerase binds to this promoter and transcribes all the genes in the operon.
After promoter, an operator sequence is present in operon. It can cause the transcription to turn on or off. For example: if a repressor binds to the operator, RNA Polymerase will not be able to move ahead as it will be blocked by the repressor. As a result translation will not occur. Hence, option C is correct.
