Your friend is having a hard time with the terminology in this unit. He is confused between the terms pure substances, mixtures, elements, compounds, homogeneous, and heterogeneous, as well as the difference between physical and chemical changes. Without just reciting the definitions, explain each term to your friend and provide at least two examples of each that will help him understand the concepts better.

Answers

Answer 1

Answer and Explanation:

Pure substances are basically chemical substances with distinct composition and properties that are constant. They may consist of one atom, molecule or compound that cannot be easily separated by physical separation technique. Examples of pure substances are iron, water, gold etc. Mixtures are made up of two or more substances that are not chemically combined together, in which each substance that make up the mixture still retains their chemical identity, and can separated by physical method. Examples of mixtures are brass made up of different metals, salt water, milk etc. Elements are pure chemical substances that are made up of a single type of atom which cannot be easily broken down. For example, hydrogen, oxygen, iron. Compounds are made up of two more different elements that are chemically bonded together by chemical bonds. Examples include NaCl or salt, which is made up of Na and Cl; Water which is made up of Hydrogen and Oxygen Homogenous mixture contains substances of uniform composition, e.g, air which consists of mixture of gases; a mixture of salt and water; milk etc. Heterogenous mixture, on the other hand contains substances whose distribution are not uniform, i.e. non-uniform. Examples are a mixture of sand and water; water and oil etc. Physical change is a type of change that involves the change of form of a matter without the chemical properties being altered. This is a reversible change. On the other hand, a chemical change is an irreversible change in which the chemical properties of a matter are changed. Examples of physical change are freezing of water, melting an ice cube, melting of wax etc.  Examples of chemical change are burning of wood, rusting of iron etc.

A 36-year-old mother of six has been recently diagnosed with type 2 diabetes. She reports increased hunger and food consumption while continuing to lose weight. What is the term used to describe this condition?

a) Polyuria

b) Anorexia

c) Polyphagia

d) Polydipsia

Answer:

Polyphagia  is the term used to describe this condition

Explanation:

Polyphagia, also recognized as hyperphagia, is the medicinal title for extreme or acute hunger. The physique with diabetes exhibits hungry and consumes more (polyphagia). Notwithstanding consuming more, he or she drops weight as the body practices fat and protein to replace for glucose.  

In independent diabetes where blood glucose levels persist abnormally huge, glucose from the blood cannot penetrate the cells – due to unless a lack of insulin or insulin resistance. This loss of energy produces an uptick in hunger.

Polyphagia

Explanation:

Polyphagia is one of the main symptoms of type 2 diabetes mellitus.  

Diabetes mellitus is a metabolic disorder which leads to increased glucose or sugar production and accumulation which circulates in the blood.  

This is either due to lack or inefficiency of the hormone insulin produced by pancreas. Due to this the glucose is not used by the cells and gets accumulated in the body. This leads to lack of energy to the cells and causes excessive fatigue which makes the diabetic often feels hungry and end up eating more.  

At the same time, since the cells cannot metabolize glucose to produce energy, the glycogen reserves stored in the muscles and other tissues is metabolized to produce energy. This loss of glycogen reserve in the muscles leads to muscle wasting and loss of body weight.

Hence although a diabetic may eat more due to polyphagia, he/she may lose weight at the same time .

Answer: A

Explanation:

Many men believe that women are too emotional to be in office

Women are disadvantaged as candidates for office because male voters almost never support female candidates. The correct option is A. Issues with women's participation. Cultural and societal barriers, such as violence, discrimination, and illiteracy, greatly influence the degree and types of participation in the politics of women.

Why is female representation important?

Better representation will guarantee that women's voices are heard and that their issues are fairly recognized, as studies have shown that women legislators are more likely than men to speak out for women's interests. Government representation has an impact on more than just policy; it is a tool for social empowerment.

Gender equality and true democracy require the active participation of women in politics. It makes it easier for women to participate directly in public decision-making and it ensures better accountability for women.

Final answer:

Sleepwalking occurs during stage N3 or slow wave sleep, which is characterized by an increased proportion of very slow delta waves. During this stage, the sleeper can engage in complex behaviors while being unresponsive to attempts to communicate with them.

Explanation:

The correct answer is  Stage N3 or slow wave sleep.

Sleepwalking, also known as somnambulism, occurs during slow-wave sleep, which is characterized by an increased proportion of very slow delta waves. During this stage, the sleeper can engage in complex behaviors, such as wandering and driving, while being unresponsive to attempts to communicate with them. Sleepwalking can occur at any time during a sleep period in some affected individuals.

Examples of sleep abnormalities that can occur during slow-wave sleep include sleepwalking, sleeptalking, nightmares, and bedwetting. In these sleep disorders, some skeletal muscle tone remains, allowing individuals to perform complex behaviors, but their consciousness is distant. Even in the deepest sleep, we are still aware of the external world and can react to stimuli.

The federal government can pursue economic policies such as spending or taxation to stimulate an economy that is contracting or to cool one that is expanding too rapidly. When the government acts to influence the economy in these ways, what is its goal?

Answers

Answer:

A. to maintain consumers' freedom of choice

C. to encourage economic citizenship

D. to promote stability in the business cycle

Final answer:

The federal government uses fiscal policy to manage the business cycle, aiming to achieve stable prices, full employment, and economic growth. It does so through changes in taxation and government spending to influence aggregate demand and supply. These actions are informed by economic indicators and balanced with other goals such as low interest rates and budget considerations.

Explanation:

When the federal government uses fiscal policy to influence the economy, the goal is to manage the business cycle and maintain macroeconomic health. This is achieved by implementing changes in government spending and taxation, which in turn influence aggregate demand and supply. For instance, during a recession, the government may reduce taxes to increase disposable income for individuals and encourage spending, or it may increase spending on projects to stimulate economic activity.

The economic goals of such policies include achieving stable prices, full employment, and economic growth. To combat inflation, the government might increase taxes or reduce spending to cool down an overheated economy. Conversely, to stimulate a sluggish economy, it could do the opposite by decreasing taxes or increasing spending, thereby boosting aggregate demand.

It's important to note that while fiscal policy is a powerful tool, there are limits to its effectiveness, and it must be balanced against other economic objectives like maintaining low/stable interest rates and a balanced budget. Additionally, economic indicators are used by the government to inform these policies and predict future economic conditions.

"The ____________________ standard allows police officers to use deadly force against people who are using deadly force against an officer or another person, as well as in certain violent felony situations."

Answers

Answer:

Defense of life standard

Explanation:

Right to self-defense allows an individual to use a counterforce to repel an attack that can take their life or injure them severely

The official statement as contained in Article 3 of the 1979 Code of Conduct states that:

"Every effort should be made to exclude the use of firearms, especially against  children. In general, firearms should not be used except when a suspected offender offers armed resistance or otherwise jeopardizes the lives of others and  less extreme measures are not sufficient to restrain or apprehend the suspected  offender".

The police also have the right to self-defense and this is employed in the defense of life standard.

Final answer:

The standard allowing police officers to use deadly force is grounded in self-defense and the necessity of force in defending life, as well as relevant legal frameworks such as Terry v. Ohio, which emphasizes the need for reasonable suspicion. It reflects a balance between officer and civilian safety, requiring that the use of deadly force be justifiable only under imminent threat or in certain felonies.

Explanation:

The standard that allows police officers to use deadly force against individuals who are using deadly force against an officer or another person, as well as in certain violent felony situations, is grounded in principles of self-defense and public safety. This concept is not only a reflection of the monopoly on the use of violence granted to state institutions like the police and military but also encapsulates a broader legal framework that includes the necessity of force in defense of life. It is also influenced by legal doctrines and judicial rulings, such as Terry v. Ohio, that set the boundaries for law enforcement's interaction with civilians, emphasizing the need for reasonable suspicion as a basis for stops and frisks.

Moreover, the formulation of laws that seek to refine and regulate the use of force by law enforcement, such as proposals to end qualified immunity or mandate de-escalation tactics, highlights the ongoing public and legislative discourse on balancing the safety of officers and civilians. The principle recognizes that the use of force, particularly deadly force, is a grave matter that requires rigorous justification, being permissible only under circumstances where there is an imminent threat to life or in response to certain violent felonies.

In instances of self-defense or defense of others, the legitimacy of using force, including deadly force, is acknowledged by the law, provided there is clear evidence that such action was necessary to prevent immediate harm. This framework aims to preserve life while allowing law enforcement to perform their duties effectively, holding them accountable for the proportionality and necessity of their actions.

Studies relating epigenetics to maternal care have demonstrated, for example, the influence of the mother's behavior on the stress index in the postnatal life of the offspring, revealing that characteristics related to maternal dedication in rats - such as breastfeeding and licking the puppies - promote the decrease in the production of stress-related hormones in the lives of mice.
