Answer:
Behavior modification
Explanation:
In psychology, the term behavior modification refers to a technique that has the goal of change altered patterns of behavior using learning techniques such as positive and negative reinforcement. In other words, behavior modification, as it names says, focuses in changing undesired behaviors by using different techniques.
In this example, Leo spends too much time in solitary activities and the teachers gave him attention whenever he was by himself. So now, the teachers were given the instruction to give Leo attention when he plays with others and ignore him when he is alone. This way, by using negative reinforcements they want to change Leo's behavior by giving him attention when he is with others, to change his behavior to a more desirable one. This example therefore illustrates Behavior modification.

Because of scarcity:Question 1 options:a) we face tradeoffs in nearly every choice we make.b) choices are unlimited.c) wants are limited.d) resources are limitless.
Answer:
a) Because of Scarcity :- we face tradeoffs in nearly every choice we make
Explanation:
Scarcity is the shortage of supply with comparison to demand.
Scarcity : Demand > Supply
Scarcity leads to trade off for each choice made, as each choice made has opportunity cost i.e something sacrifised to attain that choice.
This happens because scarcity arises out of - unlimited wants & limited resources having alternative uses.
Eg: Resources = Money Income, spending options = Food, Drinks.
If one chooses to eat a unit food, its opportunity cost i.e drinking beverages is traded off for that unit food eaten.
Prepping for a next-day exam over the course of an evening (and possibly into the wee hours of test day) poses increasing costs since A. tutors charge higher rates after 7 p.m. B. studying productivity declines sharply as the effort extends through the evening. C. the longer you choose to study will result in an increase in the number and value of foregone activities. D. evenings are a less productive time to study compared to daylight hours.
Answer:
C. the longer you choose to study will result in an increase in the number and value of foregone activities.
Explanation:
An opportunity cost refers to the loss of any potential gain by choosing or selecting an alternative from a list of other alternatives.
In the context, when preparing for a next day exam and by studying for a longer period of time increases the opportunity cost for the foregone activities.
Hence the correct option is (C).
Positive economics:________

b. postulates a relationship that is potentially refutable and then seeks to determine whether the stated relationship is correct.
c. uses value judgments to determine which policy alternatives should be chosen.
d. is of no use to policy makers because it reflects the value judgments of the researcher.
e. postulates a relationship that is potentially refutable and then seeks to determine whether the stated relationship is correct.
Answer:
Option B, postulates a relationship that is potentially refutable and then seeks to determine whether the stated relationship is correct.Explanation:
The basic purpose of positive economics is to determine the description and explanation of economic phenomena.It relies on objective data, facts, and figures.
Unlike normative economics which mostly concerns with 'what ought to be', positive economics is focused more towards 'what is'. It has an objective and fact-based approach where statements are determined through reasoning and factual analysis.
For instance, the statement "Public schools increase public expenditure" is a positive economics statement. It is a factual statement because if we look into statistics, a huge portion of money is spent on public schools.

Charter schools are generally exempt from most laws governing school districts, including laws regarding the need to report suspected child abuse and the law requiring training for mandated reporters True or False
Answer:
true
Explanation:
Jul 7, 2017 - Although charter schools are generally exempt from most laws governing school districts, all laws regarding the need to report suspected child abuse apply equally to employees of charter schools.
Final answer:
Charter schools must follow state laws regarding child welfare, including the reporting of suspected child abuse and mandated reporter training, contrary to the false claim that they are exempt from such laws.
Explanation:
The statement that charter schools are generally exempt from most laws governing school districts is false, especially when it comes to laws regarding the need to report suspected child abuse and the law requiring training for mandated reporters. Like traditional public schools, charter schools are bound by the same welfare and safety legal requirements.
Charter schools are self-governing public schools that have agreements with state governments to achieve specific educational outcomes. They receive public funding and are accountable for results like any other public school, but they operate with more flexibility in their methods. Despite their autonomy in certain operational aspects, they must adhere to state laws that protect student welfare, which includes reporting suspected child abuse and ensuring that their staff are trained as mandated reporters.

C.) The County Attorney appeared to be asking a question about the quilt, but he was actually asking another question entirely.
D.) It appeared as though Mrs. Hale was answering the question, but she actually meant something quite different with her response.

The supplement industry is regulated by the Food and Drug Administration much like medications, therefore it is safe for a student-athlete to take supplements to help gain muscle mass or to aid in weight loss.True/false
"The supplement industry is regulated by the Food and Drug Administration much like medications, therefore it is safe for a student-athlete to take supplements to help gain muscle mass or to aid in weight loss" is FALSE.
Answer: Option B
Explanation:
FDA regulates the supplement industry under the power of "Dietary Supplement Health and Education Act of 1994 (DSHEA)". These supplements have short-term benefits on human body which is covered under one of the disadvantages supplements have. Doping is totally unacceptable by any Sports Association of World, but again prescription drugs are regulated by FDA.
These have benefits, but it is mandatory for such products to have guidelines or warnings as required according to FDA norms as they have demerits too. Therefore it is not safe for students and athletes to consume weight reduction or muscle gain medications.
Final answer:
The regulation of supplements by the FDA is less stringent than that of medications, and there are safety and mislabeling concerns with supplements. Student-athletes should consult with healthcare professionals before using these products for muscle gain or weight loss.
Explanation:
The statement that the supplement industry is regulated by the Food and Drug Administration (FDA) much like medications, therefore it is safe for a student-athlete to take supplements to help gain muscle mass or to aid in weight loss is false. While the FDA does regulate supplements, they are treated more like food than pharmaceuticals, meaning they do not have to meet the same rigorous safety and effectiveness standards that medications do.
In fact, under the Dietary Supplement Health and Education Act (DSHEA) of 1994, the responsibility for determining the safety of dietary supplements shifted from the government to the manufacturer. Supplements can be sold without FDA approval unless a new dietary ingredient is added, and it is only after the FDA proves a supplement is hazardous that it may be taken off the market.
This lack of stringent regulation has led to issues such as mislabeling and contamination, with some supplements containing unlisted steroids, unsafe levels of heavy metals, or other undisclosed harmful substances. Furthermore, the claims made by supplement manufacturers about the benefits of supplements are not always substantiated by evidence, and these products often come with a disclaimer that they are not intended to "diagnose, treat, cure, or prevent any disease."
It is important for student-athletes to consult with healthcare professionals before considering the use of supplements for muscle gain or weight loss, to ensure that they are not only using a safe product but also one that is effective and necessary for their individual health and athletic goals.

An information security professional with authorization to attempt to gain system access in an effort to identify and recommend resolutions for vulnerabilities in those systems is known as a(n) Penetration tester
Explanation:
Penetration testers, additionally acknowledged as “ethical hackers,” are extremely proficient safety technicians that employ their days striving to breach processor and network defense services. These checkers serve in the information technology department to guarantee that that external sanction cannot reach an organization’s data.
They do this by attempting to mangle into systems to recognize possible vulnerabilities in the system. Most of these experts are hackers directed by professional defense auditors. They assure that a corporate web is protected from numerous web menaces.
Final answer:
A penetration tester or ethical hacker is an information security professional tasked with finding and recommending fixes for system vulnerabilities by simulating real-world attacks. They must be information literate to effectively identify knowledge gaps and enhance system security.
Explanation:
An information security professional who is authorized to attempt to gain system access in order to identify and recommend solutions for system vulnerabilities is known as a penetration tester or ethical hacker. These individuals are equipped with a variety of techniques to assess security systems, similar to those used by potential attackers, which can range from low-resourced adversaries to high-resourced adversaries like corporations or law enforcement. Understanding that techniques used by one can be used by the other emphasizes the need for comprehensive security measures. A penetration tester uses their knowledge diligently to fortify systems, making it an essential role in cybersecurity and information assurance.
It is essential for someone in this field to be information literate in the Scope pillar, which means they should be proficient in assessing current knowledge and identifying knowledge gaps. This enables them to understand which areas of the system require more attention and strengthens the security posture of the organization.

Which two ancient civilizations deeply influenced America's ideas about freedom, the value of the individual, forms of government, and systems of laws?
Answer:
Greece and Rome
Explanation:
The American Government was influenced by Ancient Greece and Ancient Rome.
Ancient Greece was a democratic state that was ruled by the people. Whereas, Ancient Rome was a Republic State which means that the voters/citizens elect the representatives to speak and act for them or on their behalf.
American Government has a Democratic Representative where citizens vote for people to represent them or speak for them.
So, the correct answer is Greece and Rome.
Answer:
Greece and Rome.
Explanation:
Early in its existence the Roman republic was governed by an elite of individuals. However,gradually the laws that permitted certain individuals to control the government were abolished, resulting in the emergence of a new elite that relied on the structure of society to retain its power, rather than the law. Same can be seen the in the case of Greece where political representation was open to a limited section of population. And the American society resembles this patter.
Suppose you're at a party at a friend's apartment. One of the guests strikes up a conversation with you about voter apathy and claims he has a pretty good idea as to why it is so high, calling it a "well-educated hypothesis." You point out (much to his annoyance) that his idea is really nothing more than a guess. In order to accurately call his idea a hypothesis, he would need to:______.
Propose a relationship between two variables
Hypotheses propose relationships between two variables. They usually include the direction of the relationship; in other words, they usually include whether the variables move in the same direction (positive) or in opposite directions (negative).
A hypothesis refers to an educated, testable prediction that is inferred from observable and measurable data. In order to label his idea about voter apathy as a hypothesis, the party guest would need to demonstrate that it is testable and that it establishes a clear relationship between voter apathy and related influencing factors.
Explanation:In scientific and research terms, a hypothesis is not simply a guess. Rather, it is an educated prediction that is testable through observable and measurable means. If the guest at the party wants to accurately call his idea regarding voter apathy a hypothesis, he needs to first make sure that it can be tested. He would need to establish a clear link between voter apathy and potentially influential factors and propose a way to measure any changes or associations in an empirical and unbiased manner.

Maggie purchased a life insurance policy. She was concerned that if she became disabled, she would no longer be able to pay the premiums. Her agent added an amendment of the policy stating that if she became disabled, future premium payments would be waived. Such an amendment to a life insurance policy is called a(n) _________.A) binder.
B) rider.
C) warranty.
D) schedule.
Answer:
B. rider
Explanation:
Final answer:
A rider is an amendment to an insurance policy that provides additional benefits or adjustments to the standard coverage. In the scenario with Maggie's life insurance policy, the rider waives future premium payments if she becomes disabled, offering financial protection against her inability to pay due to disability.
Explanation:
Maggie purchased a life insurance policy and was concerned about her ability to pay the premiums if she became disabled. An amendment to the insurance policy that specifies that future premium payments would be waived in the event of her disability is known as a rider. Insurance policies often provide the option to add a rider, which can offer a range of additional benefits or adjustments to coverage beyond the standard terms of the policy. Examples of common riders include the waiver of premium for disability, accidental death benefits, and critical illness coverage.
In Maggie's scenario, adding this type of rider helps address the concern of a financial loss due to inability to pay premiums if she becomes disabled, thereby reducing what's known as moral hazard. This customization of her policy is part of what makes insurance a valuable method of protecting against potential financial hardships connected with unforeseen events.
Explain how Tribalism created competition amongst tribes in Africa? In other words, how did the slave trade turn into an arms race between tribes, where the best defense was a good offense?
Answer:
Tribalism refers to human tendency to stay and operate within a social group or a 'Tribe' . This will make us develop a sense of loyalty and protective feeling to the people in our own tribe. But this also make people develop a sense of hostility toward other people from outside their social group.
During the slave trade era, many Tribes in Africa were in conflict with one another due to the competition to obtain resources.
The European Slave traders use this as an opportunity to divide and conquer. So they approached the tribes and promise to give them resources (such as precious metal,crops, or weapons) if they help them capture African natives to be sold as slaves.
Because of this, Tribes in Africa start to attack the members of another tribes, capture them, and give them to the European Slave traders to be sold as slaves. This is what make slave trade turn into an arms race between tribes.
Rather than captured and being sold to slavery, they choose to attack another tribes so they can sold them as slaves instead. In other words, 'best defense was a good offense'
Tribalism in Africa, exacerbated by European demand for slaves, created significant competition and conflict among tribes. This led to an arms race, where acquiring firearms was crucial for survival, resulting in frequent raids and wars.
Tribalism in Africa greatly influenced the dynamics of the slave trade and created significant competition among tribes. The European demand for slaves exacerbated existing tensions and rivalries.
Existing Slavery Practices: While slavery existed in various forms in Africa, it was different from the chattel slavery seen in the New World. Slavery in Africa often involved capturing war prisoners or individuals as part of existing practice.European Demand: European traders offered goods, especially firearms, in exchange for slaves. This demand incentivized African chiefs to capture more individuals to trade.Arms Race: Tribes that acquired firearms became more powerful and could easily defeat neighboring tribes, leading to an arms race where acquiring European weapons became essential for survival.Cycle of Raids and Wars: To maintain power and protect themselves, tribes conducted raids on others to capture slaves and secure their defense. The best defense was often a good offense, leading to an escalation of violence.Disruption of Societies: This continuous cycle of conflict and raids for slaves profoundly disrupted African societies, weakening social structures and perpetuating violence.Militarization: Tribes developed militias and trained both men and women in warfare to protect themselves and increase their offensive capabilities.Economic Incentives: Chiefs and tribal leaders were often tempted by the economic benefits of trading slaves, leading to more frequent and intense conflicts.In summary, the slave trade in Africa fostered conditions where tribes competed fiercely, leading to an arms race and a cycle of offenses and defenses that destabilized many African societies.
