Question is incomplete. Complete question is as follows:
The ____ abuts the lumen of the alimentary canal and consists of epithelium, lamina propria, and muscularis mucosae.
Answer:
Mucosa
Explanation:
Mucosa or mucosal membrane forms the lining of many cavities in the body like the alimentary canal and also covers many internal organs. It lines reproductive, digestive and respiratory system. In the gastrointestinal tract the mucosa is made of three layers: epithelium, lamina propria and muscularis mucosae.
The epithelium of mucosa is made of simple columnar epithelium cells. It consists of many types of cells like parietal cells (secrete HCL) and foveolar cells (secrete mucus). Lamina propria is a loose connective tissue present beneath the epithelium. It provides nutrition and support to epithelium. Muscularis mucosae has smooth muscle fibers which helps the glands on the surface to secrete their contents and also increase the contact between contents of lumen and epithelium.
In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. He defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
Answer:
Proteins are digested in the body when ingested food from a protein source, is broken down in the stomach by enzymes like Chymotrypsin, trypsin which are both proteins, their common goal is to convert protein into a more simple form or simplest form ( Amino acids). This enzyme (Chymotrypsin and trypsin) are Proteins and they act as biological catalysts that are responsible for breaking proteins down.
An example of how Proteins are transported by fellow proteins is the case of Ferritin. Ferritin is an essential protein in the cell of the body that regulates the amount of iron available to the body. This is important for the hemoglobin in red blood cells.
