Answer:
The correct answer is option a. "Cross-sectional study".
Explanation:
A cross-sectional study is a type of observational study used in medical and social researches. Cross-sectional studies are characterized by the analysis of data that comes from a population at a specific point of time. A research that involves studying the incidence of cholera carriers at three different villages with three different types of water supply, is an example of a cross-sectional study.
Answer:
22 map units
Explanation:
Linked genes may be defined as the genes present on the same chromosomes and they are inherited to the next progeny. The linked genes produces the recombinant progeny.
Distance between the linked gene = No. of recombinants / total number × 100.
Here the parental are 198 Tall Yellow, 192 Short Green.
The recombinant progeny are 54 Tall Green, and 56 Short Yellow.
Distance = 
Distance = 
Distance = 22 map units.
So, the distance between the genes are 22 map units.

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.
