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
lithium and fluorine
Lithium donates an electron to fluorine and make the fluorine with a negative charge and a full outer shell. Lithium consequently get a positive charge and a full outer shell. They then are attracted to each other an form a giant ionic lattice.
Carbon and hydrogen are organic so they don't
Nitrogen and Oxygen are also organic.
Chlorine can form ions but not with silicon
Answer: An observation is something you sense: taste, touch, smell, see, or hear. An inference is something you decide or think about a thing or event after you observe it.
Examples: I observe that this shoe smells musty. (Observation) I infer that my teacher has a kid.
That would be the synthesis of body mass in a primary consumer (herbivore who eats the plant).
Answer:
A) microtubules
Explanation:
The diameter of the cytoskeletal fibers are as follows -
- Microtubules about 25 nano meters
- actin filaments/micro filaments is about 7 nano meters
- intermediate filaments about 8 to 10 nano meters
Hence ,
From the above data , Microtubules have the largest diameter , it is made up of tubulin proteins which are arrange in the form of a straw - like tube which is hollow from inside , and each of the tubuline protein consists of two sub units i.e. alpha - tubuline and the beta - tubuline .
