Answer:
They increase neurotransmitter activity within certain areas of the brain associated with impulse control.
Answer:
Bilaterians have a well developed muscles which are used in both movement from one place to another and for holding things. The main limitations of protist locomotion-mechanisms is that they require medium of water for locomotion. They moved in water through pseudopods, cilia and flagella.
Longitudinal muscle are used by the worms to move from place to place. setae is present in worms which is used to move in forward direction, while jointed appendages which are attached to the body of insects helps in locomotion. Insects have skeleton that is present outside their body which is known as exoskeleton.
External appendages of radiates push the water outside in the backward direction and moved in the forward direction, while bilaterians moves from place to place through their legs which are specialized for this movement and their muscle in their hands are used for holding things.
Answer:
The answer is below
Explanation:
The complete question is in the iimage attached.
a) We can see that R1 is in series with the parallel combination of R2 and R3. Hence the equivalent resistance is given by:
b)
The current in the circuit (I) is given as:
I = emf / Req
I = 18 / 9
I = 2A
The current through resistor R1 = I1 = I = 2A
Since R2 and R3 are parallel to each other their respective currents I2 and I3 is given as:
