<span>Source control program are aimed to reduce the cultivation of
opium, coca, marijuana, poppies etc and their eradication along with other
measures. The idea is that when there will be fewer crops available for the
drug production, the price will increase and potentially less people will have
access to drugs. </span></span>
The motif is the repetitive supersecondary structures, an example of a motif is a beta-alpha-beta unit. The motifs are formed of the clusters of secondary structure.
On the other hand, the domains are globular and stable functional units in a protein. It may retain a three-dimensional configuration when distinguished from the rest of the protein.
Both the motifs and domains are stabilized by the hydrophobic interactions, they both are a unit of tertiary structure, and are dependent on primary composition.
Answer:
1) Hiatal hernia is the disorder of this 26 year old business executive. Hiatal hernia occurs when upper part of stomach pushes through an opening in the diaphragm, and up into the chest. THis opening is called a esophageal hiatus or diaphragmatic hiatus. It is basically a protrusion of the upper part of stomach into the chest through a tear on the chest through a tear or weakness in the diaphragm. The patient presents with :
- Chest pain
- Severe hurtburn
- Abdominal pain
- Frequent burping
- Difficulty in swallowing
- Throat soreness
2) Adequate lower esophageal pressure at the lower esophageal sphincter normally prevent gastric reflux into the esophagus when lying down or bending over.
3) As M3 receptors (parasympathetic) are distributed at the lower esophageal sphincter, cholinergic agonist activates these receptors and increases contraction thus rsulting in a decrease in contraction and preventing Gastroesophageal reflux. Similarly the anticholinergic are avoided because they will relax the LES and thus GERD will increase.
4) H2 antagonists are recommended because they decrease the acid secretion especially at night by blocking H2 receptors.
5) Elevation of the head of the bed recommended in order to encourage the gravitational flows of the contents in stomach toward the pyloric end.
6) Normal Stomach pH = 3-5
Normal esophageal pH = 6-7
pH at Lower esophagus in gastroesophageal patient = 3-5
pH of stomach in patient of GERD = 3-5 (same as that in normal)
Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. ... The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides
<span>Presence of oxygen means that the organisms are not anaerobic so the answer is D. algae. Eukaryotic and prokaryotic cells can be anaerobic meaning that they live in circumstances where there's no oxygen. Algae were the first that required oxygen to thrive. Cyanobacteria are like other bacteria parts of the prokaryotic cell type.</span>
