Why is there a difference between MATLAB's FFT of a zero-padded signal compared to the non-padded case - Signal Processing Stack Exchange

I created a data signal and calculated the spectrum via the fft-command in MATLAB. The data-signal itself is not periodic but it is created in a way that it can be treated as one period of a periodic
