The nurse should explain that during surgery,
an antibiotic prophylaxis is administered to prevent the incidence of surgical
site infection. The use of antibiotic before the procedure is just
one of many actions taken to help reduce the rate of wound infections.
Furthermore, the initial dose must be given most likely within 30
minutes before incision. Then, the next dose is at one to two half-lives of the
antibiotic, which is recommended for the duration of the surgery. Thus,
appropriate timing of dose is essential to the effectiveness of the antibiotic.
Answer:
lamentablemente, las vacunas pueden tener un lado malo y bueno. Las vacunas pueden proteger al cuerpo humano de enfermedades y virus que no queremos contraer. En algunos casos, las vacunas han dado a las personas malos resultados y algunos efectos secundarios han provocado la muerte. Es por eso que algunas personas prefieren arriesgarse en lugar de arriesgarse a estar protegidas o tener una mala reacción. Sin embargo, las vacunas pueden ser realmente útiles. No es muy común que una vacuna le dé a la persona efectos secundarios adversos. Algunas personas se marean o sienten náuseas, a veces tienen dolores corporales dolorosos. Depende de usted decidir si las vacunas son útiles o simplemente malas.
Answer: The correct answer is B) city hall:control center.
As per the question, model of cell looks like a city where different buildings correspond to different organelles ( membrane bound subcellular compartments like nucleus, golgi complex, vacuole, endoplasmic reticulum).
Nucleus is a specialized membrane bound compartment that possesses the genetic material ( DNA) of the Eukaryotes ( like plants and animals).
Nucleus controls all the essential activities of the cell by regulating the expression of gene ( segment of DNA corresponding to a particular protein).
Therefore, in the model of cell, city hall;control center represents the nucleus of the cell.
The evidence that ribosomes are nonspecific in carrying out their function is that b<span>acterial ribosomes can be used to make proteins encoded by human mRNAs.</span>
Energy is increases as frequency increases and wavelength decreases
Explanation:
The energy of wave is a function of its wavelength and frequency .
Wavelength is distance between two successive crests of a wave.
Frequency is the number of waves that passes a point per unit time.
Energy is directly proportional to the frequency of waves. The higher the frequency of waves the higher is its energy.
C = f ∧
C is the velocity of light
f is the frequency of wave
∧ is the wavelength of the wave
E = hf = 
= hf
h is the planck's constant
