What is the purpose of the auditory tubes opening into the nasopharynx? Explain why this may lead to plugged ears when you have a cold.

To write:
The purpose of the auditory tubes that opens into the nasopharynx. The reason for blocking of ears while having a cold.
Introduction:
Anatomy can be defined as a branch of biology that is associated with the study of the organism’s structure and its parts. In anatomy the superficial indicates the structure is closer to the surface of the body or presents more outside than another. Deep is opposite to superficial.
Explanation of Solution
The Eustachian tube:
It is also known as the auditory tube. It is a tube which joins the nasopharynx region to the middle ear. It is a portion of the middle ear.
The auditory tube permits the passage of air between the middle ear cavity and the outside environment. Consequently, the air pressure usually remains alike on both the sides of eardrum.
The auditory tube attach from the middle ear chamber to the back of the nasopharynx.
The reason for blocking of ears while having a cold is:
The blockage of an auditory tube is one probable cause of a clogged ear.
The auditory tube usually drains the mucus from the middle ear.
But due to certain upper respiratory tract allergies or infections, the eustachian tube surrounding membrane and opening can become swollen. This might trap the fluid and provide a growth medium for the bacteria and leads to the ear infections. These infections also lead to the blockage of the ears especially during cold.
Such cold and other ear infections occur commonly in children as the auditory tube is shorter, horizontal along with the smaller diameter. It makes the easy entry of bacteria. It makes the fluid movement more complex.
The auditory tube permits the passage of air between the middle ear cavity and the outside environment. Consequently, the air pressure usually remains alike on both the sides of eardrum.

Thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the absence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).1. Mutations in the lac repressor gene that would prevent the binding of lactose2. Mutations in the lac repressor gene that would prevent release of lactose once lactose hadbound3. Normally the lac repressor gene is located next to (a few hundred base pairs) and upstreamfrom the lac operon. Mutations in the lac repressor gene that move the lac repressor gene 100,000base pairs downstream.4. Mutations in the lac operator that would prevent binding of lac repressorarrow_forward
- You have returned to college to become a phylogeneticist. One of the first things you wish to do is determine how mammals, birds, and reptiles are related. Like any good scientist, you need to consider all available data objectively and without a preconceived “correct” answer. In pursuit of that, you should produce a phylogenetic tree based only on morphological features that show birds and mammals are more closely related. You will then produce a totally different tree, also using morphological features, that shows birds and reptiles are more closely related. Do not forget to include all three groups in both your trees. Based solely off the trees you produce, which relationship would you consider the more likely and why? Once you have answered that question, provide a brief summary of the “modern” understanding of the relationship between these three groups.arrow_forwardtrue or false, the reason geckos can walk on walls is hydrogen bonding between their foot pads and the moisture on the wall.arrow_forwardBiology laboratory problem Please help. thank you You have 20 ul of DNA solution and 6X DNA loading buffer solution.
