Answer:
The correct answer is a) Julianna has one form of a dopamine gene but not the other.
Explanation:
In neurodevelopmental disorders, there is attention deficit hyperactivity disorder; it is usually observed in people who have difficulty paying attention, excessive activity, do not often measure the consequences of their actions before acting, and also show problems To regulate your emotions.
Symptoms usually occur in children before the age of twelve, and the signs can be observed steadily for six months; for a diagnosis of attention deficit hyperactivity disorder, it should be taken into account that the signs follow the criteria established in the DSM-IV or ICD-10.
The exact causes of why attention deficit hyperactivity disorder is still unknown, according to studies so far, talk about different factors that are relevant for this disorder in children. Among the causes are genetic factors and nicotine exposure during pregnancy, but parenting styles are not appropriate.
Genetics is one of the leading causes of the disorder, which usually involves different genes, especially dopamine neurotransmitters, so treatments are generally stimulants or dopamine receptors.
For example, in Julianna's case, she has problems with dopamine receptor genes, and possibly her treatment is for the stimulation of dopamine neurotransmitters.
I hope this information can help you.
Final answer:
While genetics play a key role in ADHD, in Julianna's case, the smoking habits of her mother during pregnancy are a significant environmental factor that may have contributed to her ADHD. The exact cause of ADHD is multifaceted, involving both genetic and environmental components.
Explanation:
Among the choices provided regarding factors responsible for Julianna's attention deficit hyperactivity disorder (ADHD), options A and E are duplicates, and there is no ample evidence to suggest that consumption of excess sugar (option C) or inheriting both forms of a dopamine gene (option D) are directly responsible for ADHD. Instead, research indicates that ADHD does have genetic influences and can be affected by environmental factors such as maternal smoking during pregnancy. Given the information that Julianna's mother was a chain smoker, this environmental exposure is a plausible contributing factor to Julianna's condition. Although other factors like abnormal brain growth rate (option B) might contribute, there's no clear evidence to single it out as the chief cause over the genetic and environmental influences mentioned.
ADHD is associated with dysfunction of neurotransmitters, particularly dopamine, and is thought to involve genetic components, as well as brain development processes. The role of genetics in ADHD is complex and involves multiple genes. ADHD treatments typically involve behavioral therapies and medications targeting neurotransmitter balance, especially dopamine levels.
Which of the following is NOT true regarding the Columbian Exchange?
a. Rats and cats consumed ground-dwelling birds.
b. Beans, cacao, and vanilla were brought to the Americas.
c. Corn and cassava were brought to Africa.
d. Potatoes were brought to Ireland.
Answer:
b. Beans, cacao, and vanilla were brought to the Americas.
Explanation:
Beans, cacao, and vanilla come from the Americas.
Beans: According to scholars beans come from Mexico, studies have been done on nucleotides and point to the geographic origin of the wild form of beans to come from Mexico.
Cacao: Cacao is a tropical fruit that originates from the cacao tree. Cultivation began in Mexico and other areas in Central America, Amazon, and the Orinoco rivers.
Vanilla: Vanilla originated from a species of orchid native to Mexico.
The Columbian Exchange represents the transfer of goods and ideas between the New and Old World following Columbus's voyage. In this context, beans, cacao, and vanilla would not have been brought to the Americas, but instead transferred from the Americas to the Old World. Thus, statement 'b' is not correct.
Explanation:The statement b: 'Beans, cacao, and vanilla were brought to the Americas' is NOT true regarding the Columbian Exchange. The Columbian Exchange is the term for the exchange of goods, ideas, diseases, and people between the New World, or the Americas, and the Old World, consisting of Europe, Africa, and Asia, following Columbus's voyage to the Americas in 1492.
While rats and cats consuming ground-dwelling birds (statement a) can be attributed to the introduction of non-native species to New environments, corn and cassava being brought to Africa (statement c), and potatoes being brought to Ireland (statement d) represent typical examples of foods transferred in the Columbian Exchange from the Americas to the Old World.
However, beans, cacao, and vanilla (statement b) are native to the Americas and would not have been brought over from the Old World, making statement b false in regards to the Columbian Exchange.

Mark recommends that the managers at Statco should identify how and why performance has deviated beyond the acceptable range of variation, and then correct the source of the deviation. Here, Mark is recommending ________.
Answer:
basic corrective action
Explanation:
Basic corrective action refers to the identification of the cause of the problem and then solving the problem by correcting or eradicating the root cause. On the other hand, the intermediate corrective action only solves or corrects the problem at hand rather than identification of the root cause and then solving or correcting the cause. Here, the answer is basic corrective action as Mark is said to recommend the managers to identify how and why performance has deviated.
Final answer:
Mark is recommending a root cause analysis to identify and correct deviations in performance, which is a type of negative feedback to return a system to an acceptable performance range.
Explanation:
Mark is recommending a process of root cause analysis to address and correct deviations in performance. This involves gathering information from various sources such as customers and stakeholders, consulting with experts, and analyzing the data to find the underlying reasons for the variance.
Once the source of the deviation is identified, a corrective action can be taken to bring the system back to its acceptable range of performance, effectively applying a form of negative feedback to maintain equilibrium within the business operations.
According to Freud’s psychoanalytic theory, _____ occurs when the ego replaces a less acceptable motive with a more acceptable one.
Answer:
Rationalization occurs when the ego replaces a less acceptable motive with a more acceptable one.
Explanation:
Rationalization is a type of defense mechanism, a way the individual uses to cope with the anxiety a situation might cause him/her.
This specific defense mechanism appears when an unacceptable motive is replaced with an acceptable one. One's perspective changes by providing a different rational explanation to a reality he/she finds unacceptable.
For example, a student is suspended for bad grades and lack of effort. He/she would rationalize the situation by blaming the teacher instead of him/herself.
Freud's theory states that sublimation is when the ego replaces unacceptable motives with acceptable ones to cope with anxiety.
According to Freud’s psychoanalytic theory, sublimation occurs when the ego replaces a less acceptable motive with a more acceptable one.
In Freud's psychoanalytic theory, sublimation is an ego defense mechanism where unacceptable urges are redirected into more appropriate activities. This process helps in coping with anxiety and maintaining a positive self-image.
Perceptual adaptation refers to the a. grouping of stimuli into smooth, uninterrupted patterns. b. perception of movement created by the successive blinking of adjacent lights. c. perception of an object as unchanging in shape regardless of our own viewing angle. d. perceptual adjustment to an artificially displaced visual field. e. tendency for novel or unfamiliar stimuli to capture our attention.
Answer:
The answer is d.
Explanation:
This concept refers to adapting to an environment by blocking sensorial distractions. It can apply to all senses (i.e. you get used to a smell, sound or visual stimulus to the point at which you ignore it).
For example, while taking an exam in a classroom, the sound of a ticking clock on the wall might be very distracting at first. In time, your brain will automatically filter the sound so that you can concentrate.
Perceptual adaptation, as described in option d, refers to the process of adjusting our perception to cope with an artificially displaced visual field. Hence option D is correct.
When presented with sensory input that deviates from the norm, our brain adapts to the new conditions and recalibrates our perception. This phenomenon is commonly observed in experiments involving prisms that shift the visual field.
Over time, individuals learn to interpret the displaced visual information and regain a sense of spatial orientation. Perceptual adaptation highlights the brain's remarkable ability to accommodate changes in the environment and maintain a functional perception of the world, demonstrating the plasticity and flexibility of our perceptual system.

Moral lessons slightly beyond children's cognitive levels will motivate them to restructure their moral thought and promote advanced moral reasoning. This statement is closely tied tot he concept(s) of:
Answer:
The answer is equilibrium and disequilibrium.
Explanation:
Accoring to Jean Piaget's theories, equilibrium and disequilibrium refers to a situation in which the relationship between old and new knowledge is balanced. This enables a person to create new mental links, and was described by Piaget as the foundation of cognitive development.
The statement ties to Jean Piaget's theory of cognitive development and Lawrence Kohlberg's theory of moral development. Both theories assert that as children's cognitive levels advance, they become capable of more complex moral reasoning. Hence, challenging moral lessons can encourage this growth.
Explanation:The statement presented emphasizes the concept linked to Jean Piaget's theory of cognitive development and Lawrence Kohlberg's stages of moral development. Piaget noted that as children grow, their cognitive levels advance, allowing them to think more abstractly and consider the world in more complex ways. Similarly, Kohlberg argued for stages of moral reasoning that align with cognitive development.
According to these theories, when moral lessons are slightly beyond children's current cognitive capabilities, youngsters are enticed to reconsider their existing schemas - their intellectual 'toolboxes', if you will - to advance their moral reasoning. This is a reflection of Piaget's concept of accommodation, which is part of his broader theory regarding cognitive adaptation.

Jung believed that there were two levels to the unconscious mind. Name these two levels?
Answer:
Personal unconscious and collective unconscious.
Explanation:
According to Jung, there are 2 levels of the unconscious mind:
The personal unconscious: this refers to the repressed thoughts and pulses and individual has, which may have resulted from his/her interaction with the environment. The collective unconscious: it includes historical and collective elements which have been shaping humankind to act in a certain way towards different situations, sharing this psychological structure. According to Jung, this type of unconscious is hereditary and has been constructed through society, he names them the archetypes.Carl Jung believed the unconscious mind consisted of two levels: the personal unconscious, with individual experiences including repressed memories, and the collective unconscious, with universal archetypes and memories shared amongst all humans.
Carl Jung, a psychoanalyst, believed that there were two levels to the unconscious mind: the personal unconscious and the collective unconscious.
The personal unconscious is similar to Freud's notion of the unconscious, containing repressed memories and impulses along with undeveloped aspects of the personality. It is also where material from the collective unconscious that isn't ready to enter conscious awareness gets stored.
Complexes, as defined by Jung, are emotional clusters that reveal the personal unconscious. The collective unconscious, on the other hand, is a unique contribution by Jung and is shared among all humans, consisting of universal archetypes and memories inherited from our collective ancestral past.
Aengus is speaking in monotone. He asks the audience a rhetorical question, but most of the audience members don't realize this because his voice does not go up at the end of the sentence. This is an example of using poor ______________
Aengus is speaking in monotone. He asks the audience a rhetorical question, but most of the audience members don't realize this because his voice does not go up at the end of the sentence. This is an example of using poor pitch and inflection.
Explanation:
The variation in the tone or pitch of people’s voice during various times in whole conversations where voice increases and decreases referred as inflection. It also describes a departure from normal or even track. Inflection or voice modulation gives the speech a dramatic character. This helps to make the speech more interesting.
When you use this, tone changes also help to express one’s point of view in a more expressive way. Pitch denotes the sound’s quality led by vibration rates which produces it i.e, tone’s high or low degree level. From all this, the scenario acts as an example to low pitch and the inflection. That’s why, Aengus speech does not reach to the audience.
Final answer:
Poor use of prosody, reflecting a monotone delivery, indicates Aengus's weak verbal delivery skills and lack of rhetorical awareness, which results in a weakened connection with his audience.
Explanation:
Aengus is an example of a speaker who is not effectively using prosody, which is the rhythm, stress, and intonation of speech. His monotone delivery, particularly when posing a rhetorical question without the expected rise in pitch at the end of the sentence, demonstrates poor verbal delivery skills and a lack of rhetorical awareness. This lack of variation in pitch, as noted in communication studies, can make it difficult for the audience to follow the intended message and can detract from the speaker's credibility and the effectiveness of the communication.
Moreover, the issue here lies in the speaker's inability to convey the rhetorical question appropriately due to a uniform pitch, which causes the audience to miss the rhetorical nature of the question. This indicates a gap in the speaker's awareness or ability to use vocal variety to match the content of speech with its intended purpose, thereby weakening the connection with the audience.
As such, speakers are advised to avoid this kind of monotone speaking pattern and, instead, work on modulating their voice to emphasize key points and to signal different types of sentences, such as questions or statements, to aid the audience's understanding and maintain their engagement.
Hunter-gatherer societies typically survive through "the sharing of resources to ensure success with a relative absence of hierarchy and violence." (page 396) Which of the following terms best describes this type of society?
Answer:
Egalitarian society
Explanation:
Egalitarian society:
An egalitarian society is one in which is based on equality with no structure that gives authority or power to anyone but provides its people with equal rights and deals fairly.
Hunter- Gatherer Societies:
Here, each individual was treated with equality which meant that:
Every individual was equally entitled to food, wealth, all other material things such with no regards to the person's ability to find it, so everything was shared in order to ensure that all stands equal with no one superior or inferior to any one.. Nobody had the right to direct others; so decisions were entirely dependent on an individual for him/herself. Group decisions had to be made by involving everyone with no authority to a single individual.Thus the hunter gatherer societies survived through the resource sharing with no violence and hierarchical system.

According to Krashen, the sequence in which second language learners acquire language forms is similar to the sequence in which they acquire their first language. This is referred to as______
Answer:
The answer is natural order.
Explanation:
This hypothesis explains that children acquire language in a natural (fixed) order, and according to Krashen, this process occurs both for the first and second language.
Krashen rejected grammar-based education of languages if the goal was its acquisition. Instead, he assumed that people will, sooner or later, acquire a language through exposure and interaction.
Final answer:
The concept of Interlanguage, bidirectional process of language acquisition, and critical period hypothesis are key aspects of second language acquisition.
Explanation:
Interlanguage is the term used to describe the period during which second language learners have some degree of competence in producing and understanding a language, but their grammar is still different from that of a native speaker. This concept highlights that learners go through a phase where they have aspects of both languages in their linguistic repertoire.
According to Stephen Krashen, the sequence in which second language learners acquire language forms is similar to the sequence in which they acquire their first language. This is referred to as the bidirectional process of language acquisition, where theories of first language acquisition are often applied to second language learning practices.
Researchers such as B. F. Skinner and Noam Chomsky have contributed to our understanding of how language is learned and developed, emphasizing that individuals are biologically predisposed to acquire language and that language acquisition is most efficient early in life, known as the critical period hypothesis.

A. Integration
B. Assimilation
C. Separation
D. Marginalization
Answer:
The correct answer is B. Assimilation.
Cultural integration is a process in which one adopts the characteristics of another group/culture, but without sacrificing the characteristics of his/her own culture.
Separation refers to a situation where a person rejects the dominant culture so that he/she can preserve their own culture.
Marginalization represents the rejection of both one's own culture and the dominant culture.
Assimilation is the correct answer here, as it refers to the process in which one becomes culturally dominated by another society, and eventually becomes indistinguishable from the other members of that society.

Answer:
b. Null hypothesis :[tex]\mu \leq 40000[/tex]
Alternative hypothesis: [tex]\mu >40000[/tex]
Explanation:
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
On this case the Management try to proof that due to a new production process, the life expectancy of its tires has increased. So this needs to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.
Null hypothesis :[tex]\mu \leq 40000[/tex]
Alternative hypothesis: [tex]\mu >40000[/tex]
Other important thing is that on the alternative hypothesis we never can have the symbol equal.

Last year, Casey grew fresh vegetables, which she sold at her local farmers market, but this year, Casey did not plant any vegetables and went to work at a bank instead. Which of the following best explains Casey’s career change?
Answer:
While she grew and sold vegetables, Casey did not make enough money to cover her expenses and make some profit. This is the most probable reason why she opted for a career change and took a different job. Casey's opportunity costs of gardening exceeded the money she would earn from working at a bank.
Final answer:
Casey chose to work at a bank instead of growing vegetables due to being more productive at her consulting job, allowing her to maximize her income through specialization of labor.
Explanation:
The career change from Casey growing fresh vegetables to working at a bank can be best explained by the concept of specialization of labor and economic efficiency. Despite Casey's ability to grow vegetables and sell them at the local farmers market, this activity did not yield a high level of productivity compared to her other skills. Casey likely discovered she could earn more income by employing her time in a consulting job, where she is notably more productive. This decision aligns with economic principles that suggest individuals should focus on activities where they have a comparative advantage and can generate greater income. The concept is similar to an engineer choosing to work in computer science rather than painting a house because the income produced from their primary job outweighs the savings from doing a less skilled task themselves.
