kenny6666 [7]

Answer:

genotype is responsible for establishing phenotype

Explanation:

When Mendel experimented with pea plants, concept of genes and alleles had not come up yet. Through his experiments Mendel first proved that some type of combination in cells leads to a particular phenotype.

He coined the term "factors" which are today known as alleles. These factors paired up and displayed a particular phenotype. Today we know that the alleles are responsible for a genotype which ultimately results in a phenotype. Hence, he established that genotype is responsible for establishing phenotype even before the term genotype was coined.

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.
