Answer:
Option B, Middle ear
Explanation:
Nasopharynx is the upper part of throat which lies behind the nose and it connects the to middle ear. It moves the mucus produced in the middle ear to the throat which is then further drained out.
This tube is responsible for equalizing the pressure inside the ear to the pressure outside the ear. It comprises upper throat and rear side of nasal cavity.
Hence, option B is correct
Answer:
D: adhesion and cohesion
Explanation:
Water is a chemical liquid substance with unique properties that are responsible for the way it behaves. Cohesion and Adhesion are two of those properties responsible for the sticky nature of water molecules.
Cohesion is the property that makes a water molecule attracted to another water molecule by forming an hydrogen bond with one another, while adhesion is what makes a water molecule attracted to other substances aside water. These properties makes water sticky to itself (cohesive) and other chemical molecules (adhesive).

The classification is in this order: Kingdom, Phylum, Class, Order, Family, Genus Species.
The kingdom is the largest group, it contains the largest number of organisms who are the least related.
The species is the smallest group, it contains the least number of organisms who are closely related.
As you go down, from "Kingdom", species become more closely related.
So species in the same family are MORE closely related than species in the same class.
a. phosphate group, sugar, nitrogen base.
b. if it is DNA- deoxyribose sugar and if it is RNA- ribose sugar
c.Nitrogen base
d. Adenine, Gaunine, cytosine, Thymine.
