Answer:
Povidone: its action is produced by oxidation and inactivation of cellular components.
Triclosan: is absorbed by intact skin which determines its persistence and its speed of action is intermediate.
Explanation:
Povidona:
- It presents the same mechanism of action and spectrum of iodine.
- It is a water-soluble compound that results from the combination of iodine and polyvinylpyrrolidone, which improves the solubility of iodine and allows its gradual release into tissues. This effect determines less skin irritation and greater product availability over time.
- The term "available iodine" refers to the amount of iodine available as a reservoir and that of free iodine to the percentage in solution in working condition, that is, a 10% povidone iodine solution, contains 1% of available iodine and the iodine concentration Free is 1 to 2 parts of a million that remains until the available iodine is depleted. This product advantage is lost when diluted in water, since in these circumstances it behaves as an aqueous solution of iodine.
- Its activity can be diminished by the presence of blood or other organic matter.
- The concentrations commonly used as a surgical scrubber are 7.5% and 8% and in the one used for cures it is 10%.
- In relation to tincture of iodine or lugol, it presents less dermal irritation. They should be used with caution in newborns and burned
- Its antiseptic action is classified between high level and intermediate level. They are lethal in minutes for bacteria, fungi, viruses, protozoa, amoeba cysts and spores. However, in front of dry spores it requires a longer exposure time (hours).
- Iodized antiseptics have the advantage of being cheap.
Triclosan:
- It is a relatively new phenolic derivative that acts causing damage to the cell wall of microorganisms. It is broad-spectrum bacterial, better for Gram + and there is little information about its activity in viruses.
- It is absorbed by intact skin which determines its persistence and its speed of action is intermediate.
- No allergenic or mutagenic effect has been demonstrated in short periods of use.
- Its activity is minimally affected by organic matter.
- The concentrations of usual use are between 0.3% and 2%.
- It is mainly indicated for clinical handwashing where it is used in 1% breads and in 0.5% liquid preparations.
time. They first wrapped her cup with bubble wrap and recorded the
temperature of the coffee once every 15 minutes for 2 hours. They
repeated the investigation, this time using newspaper instead of bubble
wrap, but they got the same results for both materials. Which of the below
is their control or constant variable?
the type of insulation
the temperature of the coffee
the type of coffee cup
The students conducting the experiment
Answer:
The type of coffee cup
Explanation:
Because the insulation changed
The type of coffee temperature can change

Explanation:
C. Polypeptide formation.
D. Transcription.
E. Translation.
DNA, the RNA polymerase core enzyme, and the subunit are the first transcriptional components. mRNA, small and large ribosomal subunits, initiation and elongation factors, as well as tRNA, are all parts of the translation process. Thus, option D is correct.
Proteins called transcription factors are involved in the process of turning DNA into RNA, or transcribed DNA.
A large variety of proteins—aside from RNA polymerase—called transcription factors start and control how genes are transcribed.
A gene's transcription is boosted by transcription factors that serve as activators. Reducers lessen transcribing.
An enhancer or silencer is a collection of transcription factor binding sites that can turn a gene on or off in a particular region of the body.
Therefore, Transcription is the process in which a strand of DNA is used as a template for the manufacture of a strand of pre-mRNA.
