The United States Constitution is silent on the subject of political parties. The Founding Fathers did not originally intend for American politics to be partisan
After the macrophage fails the Helper T Cell stimulates the B cells (create antibodies) if pathogen is extracellular and Cytotoxic T Cells (killer T cells, release perforin) if pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.

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.

Answer:
activation energy is required for a chemical reaction to take place.
I don't think it's A. Think of all the different colors, ages, and unique predetermined ( by environment and genes) physical abilities of mice. Not to mention the fur, which would hinder any observations made off of the animals' skin (physical appearance). There would be plenty of data, but it would be inaccurate data. Just like measuring a horse in hands (when all hands are different sizes), or like determining the distance between trees in steps ( when everyone has varying lengths of stride). C is the correct answer, as it is the only data which can be replicated. ( If one scientist measures in millimeters, then another scientist will be able to get the same results.)
