Quick question about delay() and micros()

Does delay() affect micros()?
For instance, at time 100us, the program is delayed for 5us, and then at time 110us, will the micros() give me 105us or 110us?

The reason for 110us is obvious because it is.

For 105us, the program was paused for 5us so the micros() did not take this 5us into account. Therefore, it only counts 5us after the pause and it gives me 105us.

Many thanks in advance.

110us

Note that delay() can't delay for less than 1ms...

Try delayMicroseconds(x) for the smaller delays.
