Answer:
B) The inhibition of normal myelin development in the individual's brain
Explanation:
Phenylketonuria is a disorder characterized by abnormal levels of phenylalanine in the body. It is <u>caused by mutation in DNA that leads to the deficiency of an enzyme known as phenylalanine hydroxylase, which converts phenylalanine to tyrosine</u>, a fundamental substance for dopamine production - related to working memory.
Some of the symptoms of this disorder is intellectual disability, which is caused mainly by demyelination or defective myelin biosynthesis, leading to the <u>inhibition of myelin, a fatty insulating sheath that protects nerves</u>.
Therefore, the cause of the intellectual disability in the individual is <u>the inhibition of normal myelin development in the individual's brain.</u>
Answer:
The answer to the question: What kind of group work is Nicole describing, given the characteristics and the information found on research, would be: small-group work.
Explanation:
When using different techniques to ensure best team-work, avoiding social loafing in group work, and maximizing the sharing of skills between people on a gorup, small-group activities come to the forefront. Because the groups are small, there is much less of a chance of one of the members simply depending on the work of the others without doing anything. There is better chance for all members of the group to collaborate with one another, share their skills, and all participate in the activities. It is also easier for the instructor to control smaller groups, and easier for students as well, as they do not tend to blend with the background as others do the work for them. Given Nicole´s descriptions of their activities, and the formation style used by the teacher, as well as the activities, which are perfect for small groups, the group work used by Nicole´s teacher is defined as small-group.
Answer:
The correct answer is:
case-study research (a.)
Explanation:
A case study research is applied in life and social sciences to obtain an in-depth and detailed examination of a single individual or case. A case is any unit of analysis, including individuals, events, organization or an action.
Case studies can be single or multiple case studies. In medicine, as in this our example, a case study can be a finding or examination reported on a particular individual. It also finds application in sociology, psychology, anthropology, politics etc.
When selecting a case study, typical and average cases are most often not ideal, but cases with unusual results or patterns are selected, hence, unlike random sampling used in subject selection in the survey research, information-oriented sampling method is used in selecting cases in case studies. The case studies effectively seeks to compare the effects of the subject (practical cases) with the object (theoretical cases). Hence, three types of cases are selected in case studies, they include; key cases, outlier cases and local knowledge cases.
Key cases are those cases that are chosen based on the peculiarity of the circumstances surrounding such cases.
Outlier cases are extreme or atypical cases that defile normalcy hence arouse interest.
Local knowledge cases are those cases for which the researcher has local theoretical knowledge of, hence set out to go for in-depth probe.
