Answer:
Uvula.
Explanation:
Respiration may be defined as the process of exchange of gases between the body tissue, lungs and the environment. Oxygen is inhaled and carbon dioxide is exhaled out during the process of respiration.
The choanae, external nares, epiglottis and mouth plays an important role in respiration. Uvula is mainly involved in the production of the salivary gland. The uvula moistens the area and also involved in the speech process. Hence, uvula do not play important role in respiration.
Thus, the correct answer is option (b).
Basement membrane
A thin extracellular layer upon which an epithelial rests is called a basement membrane.
Basement membrane is a specialised form of extracellular matrix on which a layer of epithelial cells rests . The basement membrane is made up of a mixture of collagens, and glycoproteins such as perlecan, heparan sulphate and entactin. The basement membrane supports the overlying epithelium by preventing any association between the epithelial cells and the other cells present within the tissue. The basement membrane also functions as a molecular filter as it permit only water and tiny molecules to move through.
Answer:
The repressor protein works by binding to the gene's promoter region, preventing the production of messenger RNA (mRNA).
