Answer:
The correct answer will be option-nasal cavity.
Explanation:
The pharynx is the hollow tube which is divided into three parts: the nasopharynx, oropharynx, and hypopharynx.
The nasopharynx is the upper part of the throat present behind the nose which is 3 to 4 cm long and 2 to 3 cm wide. The nasopharynx connects the mouth to the nose and allows a person to inhale through the nose.
Thus, the option-nasal cavity is the correct answer.

Answer:
Please find the definition of viscosity, effect of heat on DNA explanation to this question below
Explanation:
Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow. In other words, it is the measure of the internal friction that exists between the molecules of a fluid, which resists its flow.
DNA in its natural state exists in a liquid solution, hence, when HEAT is applied, the heat causes ITS MOLECULES to MOVE RELATIVELY FAST and as a result the molecules lose the friction between them and begin to flow. Based on this, heat is said to make DNA LESS VISCOUS i.e. to flow more rapidly.
