Jack was sick with a cold and fever. the doctor prescribed him erythromycin, an antibiotic. analyzing the process of translation
KatRina [158]

Answer:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.

Explanation:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.

Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.

The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.

Allushta [10]

Mitosis

Mitosis is the part of the cell cycle in which the duplicated genetic material (chromosomes) within the parent’s cell nucleus is separated to produce two daughter cells that are genetically identical to the parent. Mitosis is important to life because it is involved in the production of new cells for growth and to replace damaged cells. Mitosis occurs in five stages which are; interphase, prophase, metaphase, anaphase and telophase (cytokinesis).

The nurse is caring for a 10-year-old child who weighs 82.2 lb (37.3 kg) and is to receive 2.5 ml/kg/hr of 0.45% nacl solution.
Vitek1552 [10]

Answer:

The correct answer would be 93 milliliters.

The same can be explained with the help of the unitary method.

The volume of solution required for 1 kg of weight in one hour = 2.5 milliliters (given in the question).

Thus, the volume of the solution required for 37.3 kg of weight in one hour = 2.5\times37.3 milliliters

It comes out be 93.25 milliliters.

Thus, around 93 milliliters of the solution should be given to the child of weight 37.3 kg in one hour.
