Is the name given to the clock signal that occurs evenly spaced time durations during which data signals are sent in synchronous transmissions.

Bit clock.

Answer;

Bit clock

-Bit clock is the name given to the clock signal that occurs evenly spaced time durations during which data signals are sent in synchronous transmissions.

Explanation;

The term "bit clock" is used to describe a one cycle per sample "square wave" signal used for internal synchronization within digital audio equipment.

-In synchronous  transmission data signals are sent along with a clock signal which occurs at evenly spaced time duration referred to as the bit time. On the other hand, in asynchronous  Data signals are transmitted without an associated clock signal. The time spacing between data characters or blocks may be of arbitrary duration, meaning the spacing is not standardized. Therefore, frames require start and stop indicator flags.

True.
there will be more chemicals I.e. neurotransmitters present. e. g. of neurotransmitters is acetylcholine (AcH).

if action is repeated, more neurotransmitters will be synthesized at the axon terminals to be secreted into the synaptic cleft or muscle terminal ends which ends in a response.
