Since rifamycin inhibits the enzyme RNA polymerase, which is a key enzyme for synthesizing messenger RNA, the immediate effect of this antibiotic would be the inhibition of the process of transcription.
Messenger RNA is essential for protein synthesis because it is the mediator between the information in the DNA sequence and the process of translation in which the proteins are made. Therefore, by inhibiting RNA synthesis rifampicin ultimately stops the production of proteins.

Natalija [7]

Comparing the physical features of the three types of skeletons

<u>Endoskeleton :</u>                                        

Less Flexible than cartilage    

<u>Exoskeleton :</u>

very rigid and hard    

<u>Hydrostatic skeletons  </u> :  

Less rigid and very flexible

<h3>Physical difference of the types of skeletons </h3>

The endoskeleton is the internal skeleton present in vertebrates in the form of bones which enables the movement of animals while supporting the organs of the body to remain in position. they are less flexible when compared to cartilage. Exoskeletons are outer skeletons which protect organisms and also enables them to move freely. They are very rigid and hard.

Hence we can conclude that the comparison between the types of skeletons are as listed above.

A patient has a large bruise so the phlebotomist collects a blood specimen distal to it. describe where the specimen was collect
olga55 [171]

Phlebotomy refers to a collection of venous blood. This operation can be practiced on all the superficial veins of the body, on those of the foot, the leg, the neck, the whole upper limb. It must be done in an area where there is a protruding vein and the least sensitive to limit pain to the patient. It should not be done in an altered, injured or infected area (like bruise)

The blood is collected on tubes with or without anticoagulant according to the analyzes that one wants to practice.

The reason for choosing the sampling site is for the most part practical, the veins are easily identifiable, and easily accessible for paramedical personnel. Their collection is less dangerous than that of arteries, which are generally thinner and close to the peripheral nerves.
