Answer #1

Chemical synapses allow unidirectional transmission whereas electrical synapses allow bidirectional transmission।

Electrical synapses are linked by gap junctions where presynaptic and postsynaptic membrane lies nearer to each other, these gap junctions are responsible for bidirectional transmission also they allow passage of nutrients and ATP across them.

Chemical synapses are neurotransmitter mediated where neurotransmitters are stored in the vesicles of presynaptic neurons which is released in response to stimulus, released neurotransmitter binds to postsynaptic membrane which does not lies closer to presynaptic membrane in chemical synapses. Neurotransmitter binding is this unidirectional and hence the transmission.

1.Which of the following is true about synapses: Chemical synapses and electrical synapses are two types of connections between electrically active cells (meaning that the cell can generate an electrical impulse/action potential). In an electrical synapse, a neurotransmitter is released from one cell and it affects the other cell In an electrical synapse, there is a direct connection between the two cells so that ions can pass directly from one cell to the next.

Please show your work. The answer is only for reference. You have two electrical components of two different kinds. The lifetime of the first kind is exponentially distributed with parameter .2 and the lifetime of the second kind is exponentially distributed with parameter .3. If the lifetimes of the two are independent, what is the probability that the first will fail before the second? Answer: .4

There is a choice of two data acquisition boards to be used to measure the signal identified below. One board is a low resolution 4 bit ADC with voltage settings of+/- 2.5 Volt and +/- 5 Volt max; this board costs $125. The second board is a higher resolution 6 bit ADC and a fixed voltage setting of +/2 10 Volt max; this board cost $350. Only the 6 bit board has AC coupling available. The signal to be measured...

(b) If they are the same size, they cancel each other out and disappear. If one wave is larger than the other, the smaller one disappears and the larger one shrinks but continues. (c) They get larger where they run into each other; then they continue in a direction between the direction...
