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.

Dennis_Churaev [7]

Answer:

Both ferns and flowering plants produce spores at some point in their life cycles. True

Only ferns have a gametophyte as part of their life cycle. False.

Only flowering plants produce pollen grains. true

Both a tree and a large fern plant are diploid sporophytes. True

Explanation:

Yes, both ferns and flowering plants produce spores in their life cycles. In fern plant, it produce spores on the underside of the leaves whereas in flowering plant, there are two types of spores such as microspores and megaspores. Both ferns and flowering plants have gametophyte as part of their life cycle. Flowering plants produce pollen grains whereas non-flowering plants produce spores to continue their generation. Both tree and large fern plants having diploid sporophytes which is a necessary part of their life cycle.
