Answer:
before the small- muscle exercises
Explanation:
Explanation:
a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. <em>The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles. </em>
b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. <em>Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli. </em>
c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing.<em> Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.</em>

Answer:
Specific Cell-surface receptor
Explanation:
Water-soluble hormone are not soluble in the plasma membrane therefore they can not cross the plasma membrane so they only binds to the cell surface receptor which has specific binding site for the hormone.
The water-soluble hormones comes majorly from amino acids which bind to the GPCR and activates the G protein which in turn activate adenylyl cyclase and a series of reaction gets triggered which alters the cell activity. Receptors for lipophilic hormone or ligands are present in the cytoplasm and nucleus.
Therefore the correct answer is a specific cell surface receptor.
