If voltage remains constant and resistance is increased, the amperage will decrease per Ohm's Law.
In general, increased resistance will lower current draw. See ohm's law (V = IR)
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
if we remove a resistor from the parallel connection the effective resistance value will be increased.
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
NO. In a semiconductor the resistance decreases with increase of temperature. It is their natural behavior unlike conductors and insulators. If we decrease the temperature their resistance increases. At 0 degree kelvin all semiconductors will act like perfect insulators.
In general, increased resistance will lower current draw. See ohm's law (V = IR)

Increase resistance
If you increase the number of bulbs in a circuit, the resistance in the circuit will increase, causing the motor's speed to decrease. If you decrease the number of bulbs, the resistance in the circuit will decrease, causing the motor's speed to increase.
That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Increase
You cannot increase amperage without changing voltage or resistance. Ohm's law states that voltage is current times resistance. You cannot change one alone. Not even changing frequency in a capacitive or inductive circuit will do this, because changing frequency represents a change in reactance, which is effectively a change in resistance.
Increase the voltage applied to the wire. Decrease the resistance of the wire.
To increase frictional force, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or increase the coefficient of friction by using materials that interact with more resistance. To decrease frictional force, you can use lubricants to reduce surface interaction, decrease the normal force, or use smoother materials to reduce resistance.
Well, the more the air resistance, the lower the acceleration.
it so increases it
