Answer:
Molecular mass or vapor density
Explanation:
The empirical formula is the simplest formula of a compound. The molecular formula expresses the exact formula of the compound. To derive the molecular formula, we need information about its molecular mass or if given the vapor density.
(Empirical Formula)n = Molecular formula ------(i)
n = number of repeating units of the empirical formula present in one mole of the molecule
also, (molar mass of empirical formula)n = molar mass of compound
From here, we can find n and insert in (i) above.

Explanation: think of it like a speedometer in a car it can only go to that speed
Answer:
Epithelial cells
Explanation:
Epithelial cells are cells that secret mucus to prevent friction between organs. Like between the Heart and Lung.
Answer:
Denaturation.
Explanation:
Denaturation may be defined as the process at which the proteins are placed at the unfavorable environment. The proteins are treated at high temperature, pressure and the in the presence of different chemicals.
The high temperature changes the three dimensional shape of the protein and unfold the native state of the protein. This result in the loss of the biological activity of the protein. Renaturation of protein is possible only if the primary structure of the protein is not destroyed.
Thus, the correct answer is option (3).
