Breathing into and out of a paper bag for a long period of time will lead to?
Ilya [14]

Breathing into and out of a paper bag for a long period of time will lead to respiratory acidosis.

<h3>What is respiratory acidosis?</h3>
  • When the lungs are unable to expel all of the carbon dioxide the body produces, a condition known as respiratory acidosis develops.
  • Body fluids, particularly the blood, become too acidic as a result.
  • The main causes of respiratory acidosis are inadequate ventilation and carbon dioxide buildup.
  • The main issue is an increase in arterial carbon dioxide partial pressure (pCO2) and a decline in the arterial bicarbonate to arterial pCO2 ratio, which causes a drop in blood pH.
  • When there is acute respiratory acidosis, the body initially tries to make up for it.
  • If the acidosis lasts more than 12 hours, a reaction known as metabolic compensation2 takes place.
  • By increasing the release of hydrogen ions through ammonium, the kidneys will lower the blood's acidity.
  • Too much carbon dioxide in the body can result in general symptoms including headache, exhaustion, and twitching muscles.
  • Frequently, it goes away fast on its own.
  • But in cases of severe hypercapnia, the body is unable to return to a stable CO2 level, and the symptoms are more severe.

A bacterium is infected with an experimentally constructed bacteriophage
dem82 [27]

The complete question is:

a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have

A) T2 protein and T4 DNA

B) T2 protein and T2 DNA

C) a mixture of DNA and proteins of both phages.

D) T4 protein and T4 DNA

E) T4 protein and T2 DNA

A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.

A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.

  • The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.
  • Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
  • As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.

In conclusion, The new phages produced would have D) T4 protein and T4 DNA.
