A drain with closed wound suction will be used for any neck procedure that requires extensive dissection. why do you think is it
artcher [175]
Close suction drains play very crucial in surgical wound healing. It is important that the wound suction drain works properly because the proper healing of the wound depend on it. If the wound suction drain do not work properly, it will be difficult to obtain accurate recording of the volume and the contents of the drainage that is coming out from the wound. Thus, it will be difficult to monitor for excessive bleeding, infections and things like that which may prevent proper healing.

In STR profiling, PCR is used to obtain enough DNA to then detect the number of STRs at I specific loci.​
Licemer1 [7]

PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.

<h3>What is Short Tandem Repeat (STR) profiling?</h3>

Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.

The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.

Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.

Leer el siguiente texto de las teorías evolutivas y expresar cuales son las principales semejanzas y diferencias
IceJOKER [234]

Answer:

Lamarck creía que la evolución era una consecuencia de la presión ambiental mientras que Darwin expresó que el mecanismo de evolución es la selección natural

Explanation:

Lamarck desarrolló una teoría en la que propuso que los organismos evolucionaban como una consecuencia de la influencia ambiental y que los cambios fenotípicos causados por el ambiente podía ser trasmitidos a través de generaciones. Por otra parte, Darwin desarrollo una teoría en la cual las especies evolucionan a través de un proceso que él denominó selección natural (supervivencia del más apto) : aquellos organismos mejor adaptados a su ambiente tendrán más chances de sobrevivir y de reproducirse, pasando sus genes a la siguiente generación. En relación al cuadro comparativo, Lamarck creía que las jirafas se adaptaban a su ambiente para sobrevivir, mientras que Darwin propuso que aquellas jirafas que mejor se adaptaban a un ambiente cambiante tenían más chances de sobrevivir. Lamarck también creía en la idea del uso y desuso de órganos: las jirafas con el tiempo podía desarrollar cuellos más largos estirándose para alcanzar las hojas de los árboles de copas más altas y transmitían esta característica a su progenie, mientras que Darwin propuso que aquellas jirafas con cuellos más largos tenían más chances de sobrevivir que las que tenían cuello corto (selección natural), y las jirafas de cuello largo transmitían este rasgo a su descendencia (descendencia con modificación). Lamarck creía en la idea que las especies no poseen un antecesor común, mientras  que Darwin creía que todo el árbol de la vida está conectado a través de antepasados comunes. Finalmente, Lamarck pensaba que las especies no podían extinguirse, mientras que Darwin propuso la idea que las especies se extinguen y surgen otras nuevas a través de procesos de radiación adaptativa.

Maternal iron stores transferred to the fetus during the end stages of pregnancy generally run out by the time an infant is six
Anna11 [10]
The appropriate response is Iron-fortified breakfast cereal or little measures of lean meat. Invigorated sustenances are nourishments to which additional supplements have been included. Cases of these supplements incorporate vitamin A, B vitamins, vitamin D, folic corrosive, iodine, and iron. The first reason for nourishment stronghold was to diminish the event of supplement inadequacies.
