Answer:
Harry has a lower density of Baryon than Sally.
Explanation:
Baryons are subatomic particle, such as a nucleon or hyperon, that has a mass equal to or greater than that of a proton.
Baryons belong to the hadron family of particles, which are the quark-based particles. They are also classified as fermions, i.e., they have half-integer spin.
Baryons are made up of three quacks.
Deuterium is one of two stable isotopes of hydrogen.
From the question; The more baryons there are in the universe (a higher density of baryonic matter), the lower the ratio of deuterium to hydrogen, THEREFORE, HARRY HAS A LOWER DENSITY OF BARYON THAN SALLY
