is anthropology better than sociology?
Answers
Answer: Yes, Anthropology is the best
Explanation:
A comprehensive understanding of various cultures, abilities in observation and analysis, critical thinking, clear communication, and practical problem-solving are all enhanced by studying anthropology. The study of anthropology challenges us to broaden our vantage points beyond our own familiar social circumstances and consider other people's points of view.
Anthropology is the study of people, both current and former. Cross-cultural contrasts in social institutions, cultural ideas, and communication methods provide inspiration for anthropological perspectives. Cultural anthropology, archaeology, linguistic anthropology, and biological anthropology are the four main topics of study for anthropologists.
John experiences anxiety whenever he is in a crowded room, and he leaves the crowded room to decrease his anxiety. John’s behavior of leaving the crowded room to decrease his autonomic nervous system arousal is:
Answers
Answer:
negatively reinforced
Explanation:
The automatic nervous system is the system of the human body that controls and regulates the functions of the body unconsciously. The response is provided by the body to either face or to move out of the situation. Usually, there arises a change in the frequency in the blood pressure, the process of digestion, metabolism, and other body processes.
As per the given excerpt, the automatic nervous system arousal of John is negatively reinforced. The action of John moving out of the crowded room reflects his action against anxiety. This highlights the action adopted to minimize anxiety and therefore is negatively reinforced.

Although individuals in the field should pay attention to these discussions, sociologists would typically claim that their field is primarily concerned with three theoretical orientations. These three theoretical perspectives are Conflict Perspective, Symbolic Interactionism, and Structural Functionalism.Putting human behaviour into its larger social framework helps us comprehend it better from a sociological point of view.

Be sure to include whether you agree with this assumption and why you agree or disagree. Subsequently, identify the gaps in your state foster care system that contribute to the idea that foster care is harmful to children. Then, compare the benefits and shortfalls of permanency planning and family preservation. Finally, provide a description of whether you prefer the permanency or the family preservation approach as a child welfare social worker and why you prefer it.
Answers
Hello. You did not inform the survey to which the question refers, which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.
The preservation of the family promotes child safety, establishing an environment in which the child can trust and feel welcomed. This promotes a strong well-being and comfort, leaving the child more confident and happy to be with her/his family. This factor may not be presented in a foster care situation, as the child is subjected to living with a family that is not hers/his. This, in addition to causing insecurity to the child, can cause this family to show negative and abusive behaviors towards children who are not part of this environment. In this case, for foster care to be beneficial, it is necessary to have a strong supervision of social assistance in relation to the treatment that the child is receiving. This inspection is one of the major failures of social assistance in most of the country, which contributes to the conclusion that this type of assistance is malefic. In this case, it is preferable that family preservation is chosen more often, for the welfare and safety of the child, this approach should only be discarded if absolutely necessary.

Answers
Typically, clay acts as an aquitard, preventing water from flowing freely. Sand and gravel are suitable aquifer materials because they are both porous and permeable. The most permeability is seen in gravel.
What is permeable and piosity ?Any rock or loose sediment has the qualities of porosity and permeability. Both are influenced by the quantity, size, and connectivity of rock openings. More specifically, a rock's porosity is a gauge of how well it can contain a liquid.
In mathematics, it is the open area within a rock divided by the volume of the entire rock (solid and space). The ease with which a fluid can pass through a porous substance is measured by its permeability. Even if a rock has a large number of pores, it won't have permeability if the pores are not connected.

As per the statistic given by the Insurance agency, a typical, driver meet with a mishap every 17.9 years. Some of which might be lethal and some may not. So assuming that one gets his permit to drive at an age of 16 years and resigns at an age of 60, we can think about close to 54 years of driving. Along these lines assuming we partition 54 by 17, we get 3.17

9. The main reason for the increase in the number of households is:
A. Many households own several homes
B. Land costs have decreased
C. Size of households has become smaller
D. Mortgage rates have fallen consistently over several decades
E. None of the above
Answers
The main reason for the increase in the number of households is generally considered to be the decrease in the size of households. Option C is the correct answer.
Families have been having fewer children on average, and there has been an increase in the number of single-person households, couples without children, and people living alone. These changes have led to a greater number of households overall.
While options A, B, D, and E may have some influence on specific cases or regions, they are not the primary reasons for the overall increase in the number of households.
Multiple home ownership (option A) is relatively uncommon, land costs (option B) can vary and may not necessarily lead to an increase in households, and mortgage rates (option D) can fluctuate but do not directly impact the number of households.
Option E, "None of the above," is also not the most accurate answer in this context, as the decrease in household size is widely recognized as a key factor.
