There is no option provided related to the experiment that is conducted to test the effect of pepsin under various conditions. However, answering the question will be easier if students understand the conditions under which pepsin works best. Pepsin will be active and work best in acidic conditions with pH values ranging from 1.5 to 2.5.
<h3>Why would pepsin work better in acidic environments?</h3>
Pepsin is a digestive enzyme that aids in the digestion of proteins contained in food. Pepsin is secreted by gastric chief cells as a dormant zymogen known as pepsinogen. Parietal cells in the stomach lining release hydrochloric acid, which lowers the stomach's pH. Pepsin is activated by a low pH, 1.5 to 2, and works optimally at pH 1.8 since the carboxylic acid group, which is located on the amino acid in the active site of pepsin, must be protonated, or connected to a hydrogen atom. At low pH, the carboxylic acid group protonates, allowing it to catalyze the chemical process of chemical bond breakdown.

Answer: the facades of our buildings are the Third Skin
Explanation: The Third Skin describes the intimate relationship between humans and the living space.
Alex found some information about a new treatment for asthma on the Internet and shares this information with her doctor. Since Alex's information is accurate and relevant, her relationship with her doctor will most likely benefit, as Alex and her doctor can discuss this new information.
Asthma is a disorder that makes it difficult to breathe because the person's airways shrink, swell, and create excess mucus due to inflammation.
Even mild cases of asthma can make it difficult to carry out regular tasks. It might occasionally result in a potentially fatal attack.
- Alex's choices will not deteriorate as the doctor will not feel challenged rather it is a good thing that the patient is aware about his condition and treatments.
- Alex will still trust her doctor and will discuss the new information t get the best diagnosis.

Answer:
The given statement is false.
Explanation:
Hyperventilation is a condition when the rate of breathing increases resulting in the loss of more carbon dioxide from the body than the amount that the body can produce., thus dis balancing the equilibrium between the oxygen intake and the removal of carbon dioxide from the body and reducing the concentration of carbon dioxide from the blood.
With the reduced concentration of carbon dioxide in the blood the equilibrium of the carbonic acid in the blood is disturbed resulting in increase of hydrogen concentration in the blood.
Thus Hyperventilation causes reduction of carbon dioxide from the blood. Hence the statement is false as retention of carbon dioxide will cause increase in concentration of carbon dioxide.
By measuring the anatomical landmark from the earlobe to the nose of the patient.
The oropharyngeal airway is an intraoral J-shaped medical device, which is inserted in the mouth of a patient who is unconscious like in paralysis condition etc. It is important to select the appropriate size of the oropharyngeal airway tube before inserting it into the patient's mouth to avoid any complications. The airway device prevents the closure of the epiglottis and opens the mouth for breathing. It is mainly used when the patient is at respiratory obstruction by the formation of excessive mucous or blockage of the airway by the tongue.
