Which type of epithelium lines the inferior portions of the pharynx?
konstantin123 [22]

Answer:

The type of epithelium that lines the inferior portions of the pharynx is stratified squamous epithelium.

Explanation:

The pharynx is a structure made up of muscles and mucous membranes -like many internal organs- that is part of the respiratory system and is an intermediate step in the digestive tract.

This structure has two portions:

  • <em>Upper or nasopharynx </em>
  • <em>Lower, or oropharynx, in contact with the airways. </em>

Some even propose that the borderline surface between the pharynx and larynx can be called the laryngopharynx, due to its tissue structure.

The lower portion of the pharynx is covered by a squamous stratified epithelium, the inner layers of which rest on a basal lamina. The more superficial layers provide protection to the interior of the pharynx against friction, in addition to remaining lubricated by mucous secretion at that level.

jeyben [28]

Answer:

1. ddaa

2. DdAa

3. One from each parent

4. False

5. 0.25

6. 0.25

7. 0.25

8. 0.5

Explanation:

The remaining part of the question is  

1. What is Jane's genotype?  

2. What is Paul’s genotype?  

3. Where did Jane get her gene for curly hair? From her mother or father?  

4. True or False: Jane's mother was heterozygous for curly hair?

5. What fraction of Paul and Jane's children should have curly hair and dimples?  

6. What fraction of their children would have straight hair and no dimples?  

7. What fraction should have dimples but not curly hair?  

8. What is the probability of getting any offspring with dimples

Solution

1. Genotype of Jane's mother -ddaa

2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa

3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was  Aa)

4. False.  She was having straight hair

5. Offspring of  Paul and Jane  

DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)

4 out of 16 offspring will have curly hair and dimples = 0.25

6. ddaa, 4/16 = 0.25

7. Ddaa , 4/16 = 0.25

8. Ddaa, DdAa, 8/16 = 0.5
