Prothrombin time will be prolonged due to deterioration of factor V.
Explanation:
Prothrombin time (PT) assess the function of the blood clotting factors which include – vitamin K and factors I, II V, VII and X.
The PT will be longer than the standardized international normalized ratio (INR) if under any blood-thinning medications, absence or deterioration of blood clotting factors, or any inhibitors which inhibit the clotting factors.
While conducting a PT test, the blood sample is taken in a small test tube containing sodium citrate. The sodium citrate is an anticoagulant which will prevent coagulation.
The sample tube should be filled with the blood collected and the tube should also be inverted frequently to prevent any coagulation. The specimen collecting tube with sodium citrate is usually marked with a light blue color.
Sodium citrate is used as the anticoagulant because it keeps the specimen stable with the help of its calcium chelating properties. However, at room temperature the specimen can be stable for about four hours.
Prolonged h and hours will deteriorate the coagulation factor V because the pH of the citrate solution is high mostly above 8.0 and hence prolonging the specimen in it will deteriorate the labile factor V

Answer:
It can help us determine the DNA's approximate sizes and charges.
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge. Electrophoresis involves running a current through a gel containing the molecules of interest. Based on their size and charge, the molecules will travel through the gel in different directions or at different speeds, allowing them to be separated from one another.
Once the fragments have been separated, we can examine the gel and see what sizes of bands are found on it. When a gel is stained with a DNA-binding dye and placed under UV light, the DNA fragments will glow, allowing us to see the DNA present at different locations along the length of the gel.
A well-defined “line” of DNA on a gel is called a band. Each band contains a large number of DNA fragments of the same size that have all traveled as a group to the same position. A single DNA fragment (or even a small group of DNA fragments) would not be visible by itself on a gel.
By comparing the bands in a sample to the DNA ladder, their approximate sizes can be determined.
Answer: E) Emesis from irritation of the stomach.
Explanation:
The gastroesophageal reflux disease, is a disorder of digestive system which affects the esophageal sphincter. Many people suffer from heartburn or acid indigestion caused by this disease. The overweight and pregnant individuals suffer from this disease.
In normal process of digestion, the esophageal sphincter opens to allow food to pass into the stomach and close so as to prevent food and acidic juices from stomach from flowing back to the esophagus. This disease makes the esophagus sphincter weak , that causes the stomach's contents to move up into the esophagus, this may result in vomiting. The acids in the stomach may cause ulcers.
