Answer:

False.

Explanation:

Zwitter ion may be defined as the molecule that contains the net neutral charge. The change in pH can change the charge on the zwitter ions. Amino acids can exist in the form of zwitter ions.

The basic environment, causes the deprotonation of the ammonia group. The carboxyl end of a protein release the hydrogen ions in the acidic environment , not in the basic environment.

Thus, the answer is false.

Some research supports the claim that individuals with antisocial personality disorder may not exhibit the same increase in stre

Arisa [49]

Answer:

The statement is true.

Explanation:

The results of the investigations carried out in relation to the link between cortisol secretion and personality reveal differences in the reported evidence. Some of this research indicates that personality traits or disorders play a relevant role in individual differences in the endocrine response to cortisol, both in its basal levels and in the face of stressful stimuli.The relationship between antisocial personality and cortisol levels has been described in several investigations. Among the most reported neuroendocrinological abnormalities in antisocial men is a decrease in cortisol secretion levels. In this regard, Moss, Vanyukov and Martin conducted a case control study comparing cortisol secretion in stressful situations in children between 10 and 12 years of age at risk of presenting aggressive and abusive behavior in adolescence based on their family history. The groups were formed in relation to the presence or absence of a family history of aggression and substance abuse, specifically in the parents. The results found showed that children had a higher risk of antisocial behavior, if their parents had a history of substance abuse and violent behavior, they had lower levels of cortisol secretion in stressful situations than children in the control group whose parents did not present these behaviors negative. The researchers argue that these results could be indicating that a lower increase in cortisol levels in the face of stressful situations could be a biological marker of future antisocial adolescents. Likewise, a longitudinal study with 38 school-age children who had symptoms of aggressive behavior (clinically reported), who were assessed for the circadian rhythm of cortisol in saliva during the second and fourth years of schooling; reported the relationship between the decrease in HPA axis activity and the presence of severe and persistent aggressive behaviors.

Brain-imaging techniques can determine all of the following EXCEPT :

pantera1 [17]

Answer:

The answer is letter c, The structure of individual neurons.

Explanation:

Brain-imaging technique- this comprises of different techniques for analyzing the brain's activities as well as structure, function and other problems.

There are many brain-imaging techniques such as Positron Emission Tomography or PET, which traces the part of the brain that is activated during specific tasks as well as the localization of brain activity in response to a specific stimulus. These areas are seen with high radioactivity.

Patterns of blood flow in the brain can be detected by using MRI (Magnetic Resonance Imaging) test. There is an increase in blood flow to areas in the brain with high activity level.

With the explanation given, it shows that letter c is the only choice that the brain-imaging techniques cannot determine.

Dental history dates back to ancient civilizations. Who are some of the early

olganol [36]

Answer:By the 1700s, dentistry had become a more defined profession. In 1723, Pierre Fauchard, a French surgeon credited as the Father of Modern Dentistry, published his influential book, The Surgeon Dentist, a Treatise on Teeth, which for the first time defined a comprehensive system for caring for and treating teeth. Additionally, Fauchard first introduced the idea of dental fillings and the use of dental prosthesis, and he identified that acids from sugar led to tooth decay.

Dentistry is one of the oldest medical professions, dating back to 7000 B.C. with the Indus Valley Civilization. However, it wasn’t until 5000 B.C. that descriptions related to dentistry and tooth decay were available. At the time, a Sumerian text described tooth worms as causing dental decay, an idea that wasn’t proven false until the 1700s!

In ancient Greece, Hippocrates and Aristotle wrote about dentistry, specifically about treating decaying teeth, but it wasn’t until 1530 that the first book entirely devoted to dentistry—The Little Medicinal Book for All Kinds of Diseases and Infirmities of the Teeth—was published.

Which 2 interventions should the nurse be prepared to perform for a patient who is receiving an epinephrine infusion?

podryga [215]

The nurse should be prepared to monitor pulse and ventilation immediately for a patient receiving epinephrine infusion.

Epinephrine, often called adrenaline, is a very potent drug that may produce adverse side effects if taken in inappropriate amounts. It is used to treat cardiac arrest, hypotension, or severe allergies, known as anaphylaxis, caused by some insect's bite.

Some of its side effects include respiratory problems, dizziness, headache, weakness, nausea, pale skin, sweating, feeling nervous, anxious, or fearful.

Thus the nursing interventions should be performed as:

● Assess the patient's respiratory count, pulse, blood pressure, and urine output continuously

● Administer the dose carefully in appropriate amounts- usually, the dose does not exceed 1mg

● Report it to the doctors if any of the side effects do not vanish in 20 minutes after the infusion.
