2. restricted or unrestricted diet.
Explanation:
The presented experiment is designed to see if the diet has a role in reducing high blood pressure. In this experiment two factors, a low salt diet and a vegetarian diet believed to have a promising effect.
Men with high blood pressure are assigned to random diets but these randoms diet has two common factors which are normal or vegetarian diet and restricted or unrestricted salt diet to check their individual effect on reducing high blood pressure.

1. normal or vegetarian diet, and
2. restricted or unrestricted diet.

Answer:
Aerosols may be created when the hot loop touches the culture.
Explanation:
The insertion of the hot loop, will make the broth and the bacteria to boil briefly, and this will create aerosols containing bacteria.
This is very dangerous especially to the students , because the aerosols created is air borne and can be inhaled by the student and enter the respiratory tract, or settle on his/her skin.
Note that, when a loop produce a hissing sound when placed in a broth culture means that, it has not cooled sufficiently or as expected.
