according to the hubble law the more distant galaxies ________.
are more elliptical.
are fainter.
have more redshift.
are older.
have more mass.

Explanation:

Hubble's law states that the recessional velocity of a galaxy is directly proportional to its distance from Earth ($v = H_0 d$, where $v$ is velocity, $H_0$ is Hubble constant, $d$ is distance). Recessional velocity is observed as redshift (Doppler effect for light from moving-away objects). Thus, more distant galaxies move away faster, showing more redshift. Other options (shape, faintness, age, mass) are not linked to Hubble's law.

Answer:

have more redshift.
