Explain the characteristics scientists use when observing organisms and placing them in the six kingdoms

Art [367]

There were several characteristics that the scientists kept in mind while classifying, these are mobility, cell structure, cell type, body type, etc.

<h3>What is classification?</h3>

Classification is the grouping of organisms based on similar characteristics which makes them different from other groups.

There are the following characteristics to classify them:

Mobility: it includes whether the organism is moving or sessile.
Cell type: it includes eukaryotic or prokaryotic cells.
Cell structure: it includes whether the cells have a cell wall or not.
Body type: it includes whether the organism is unicellular or multicellular.
Mode of nutrition: It includes whether the organism is parasitic, autotrophic, symbiotic, consumer, etc.

Thus, these are the characteristics that the scientists kept in mind before drawing classification.

What are mechanisms of action of Triclosan and Povidone?

NNADVOKAT [17]

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.

- <em>It is absorbed by intact skin which determines its persistence and its speed of action is intermediate. </em>

- 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.

The success of the program to eradicate smallpox has stimulated experts to pursue what they had not previously considered possib

Anika [276]

Answer:

This is an English Language question and not Biology.

Here is full question:

The success of the program to eradicate smallpox has stimulated experts to pursue what they had not previously considered possible -- better control, if not eradication, of the other infections such as measles and yaws.

A. what they had not previously considered possible -- better control, if not eradication, of the other infections such as

B. what they had not previously considered a possibility -- better control, if not eradication, of such infections like

C. something they had not previously considered possible -- better control, if not eradication, of such infections as

D. something not considered a previous possibility -- better control and perhaps eradication, of other infections such as

E. the possibility of what they had not previously considered possible – better control and possibly eradication of infections like

The answer is C

Explanation:

'What they had not previously considered a possibility' is too specific. It might be pointing to just one possibility. But there are two possible possibilities here, 'something' sounds better.

The action in the past, which was the eradication of smallpox, has triggered something, which was the better control or eradication of other diseases.

Previously, the experts had not considered better control possible, but then this action was triggered by the eradication of small pox. Now the experts are considering better control possible because they have been stimulated to pursue it.

A doctor hypothesizes that a patient's digestive system is not properly secreting digestive enzymes. Which of the following woul

KATRIN_1 [288]

Answer: B. The stomach is no longer secreting pepsin.

Pepsin is a protein digesting enzyme that performs protein digestion in the stomach.

Bile is produced by the liver for the digestion of lipids in small intestine. The pancreas secretes pancreatic juice, not bile.
