Question 1
A study found that teens who smoked e-cigarettes were more likely than other teens to start smoking regular
cigarettes. Teens ages 12-17 that never smoked a regular cigarette were asked to report their use of e-cigarettes.
One year later, the same teens were asked if they had smoked a regular cigarette. 4.6% of participants, one year
later, had tried a regular cigarette. However, 18-19% of those who said they had used e-cigarettes at the
beginning of the study had tried regular cigarettes.
Part A
• What is the most appropriate conclusion that can be drawn from the study?
Part B
In a follow-up study, researchers wanted to examine the effect of nicotine on brain activity. How would
researchers examine the following concept in this study.
• Dopamine and the reward center
Part C
Humans display various reactions that are characterized by opposing tendencies. Use a specific physiological
mechanism to explain how both aspects of the opposing processes apply to the following concepts.
Neural firing

Hope this helps lol.

The complete set of cases from which samples may be drawn is called as population. Thus option D is correct.

A population can be defined as complete group of individuals which  comprises a nation or a group of individuals having common characteristic features.

It is a pool of  individuals from which the statistical sample is drawn for a study purpose, so the election of individuals grouped by a common feature which can be called as population.

For, a statistical analysis of a sample of a population must report a standard deviation, or standard error,  so that the results from the entire population can be determined properly.

Thus option D is correct.

Explanation:

Interrogative phrases are those that present a type of questioning, a type of question. In “Gettysburg Address,” Lincoln makes no question and for that reason, we can say that there are no interrogative phrases in the speech.

Almost every discourse contains declarative sentences that are phrases where the author finds a fact. Lincoln uses this type of phrase right at the beginning of the discreet, when he states that "87 years ago, our parents gave birth, on this continent, to a new Nation, conceived in Liberty and devoted to the principle that all men are born equal."

Lincoln also uses imperative phrases that are phrases used to express a request, an order or an instruction. It is possible to see these phrases at the very end of the speech when Lincoln says "It is up to us, the living, to dedicate ourselves today to the work unfinished up to this point so remarkably advanced by those who fought here."

The distance between these given points on a coordinate plane is equal to: B. √57

Given the following points:

Mathematically, the distance between points that are on a coordinate plane is calculated by using this formula:

Distance = √[(x₂ - x₁)² - (y₂ - y₁)²]

Substituting the given points into the formula, we have;

Distance = √[(4 - (-7))² - (3 - (-5))²]

Distance = √[(4 + 7)² - (3 + 5)²]

Distance = √[11² - 8²]

Distance = √[121 - 64]

Distance = √57

Papermaking

Explanation:

Paper was invented in China during the 3rd century B.C., and its use spread via the Silk Road, arriving first in Samarkand in around 700 A.D., before moving to Europe through the then-Islamic ports of Sicily and Spain

Answer/Explanation:

[tex] 12^2 = 16*x [/tex] (altitude to hypotenuse theorem)

Solve for x using this equation

[tex] 144 = 16x [/tex]

[tex] \frac{144}{16} = x [/tex] (division property of equality)

[tex] 9 = x [/tex]

[tex] x = 9 [/tex]

[tex] y^2 = 12^2 + x^2 [/tex] (pythagorean theorem)

[tex] y^2 = 12^2 + 9^2 [/tex] (substitution)

[tex] y^2 = 144 + 81 [/tex]

[tex] y^2 = 225 [/tex]

[tex] \sqrt{y^2} = \sqrt{225} [/tex]

[tex] y = 15 [/tex]

[tex] z^2 = (x + 16)^2 - y^2 [/tex] (pythagorean theorem)

[tex] z^2 = (9 + 16)^2 + 15^2 [/tex] (substitution)

[tex] z^2 = 25^2 + 15^2 [/tex]

[tex] z^2 = 625 + 225 [/tex]

[tex] z^2 = 850 [/tex]

[tex] \sqrt{z^2} = \sqrt{850} [/tex]

[tex] z = \sqrt{25*34} [/tex]

[tex] z = 5\sqrt{34} [/tex]

The balanced chemical equation showing the reaction between dinitrogen pentoxide (N₂O₅) with water H₂O can be computed as follows:

[tex]\mathbf{N_2O_5 + H_2O \to 2HNO_3}[/tex]

From the given information, the amount of water H₂O is present in excess, as such dinitrogen pentoxide (N₂O₅) is regarded to be the limiting reagent.

However,

∴

1.93 moles of N₂O₅ will result in = (2 × 1.93) moles of HNO₃

= 3.86 moles of HNO₃

Therefore, we can conclude that the reaction between 1.93 moles of N₂O₅ with water will produce 3.86 moles of nitric acid HNO₃.

Well, global economic growth and industrial productivity are both the driving force and the major consequences of globalization. They also have big environmental consequences as they contribute to the depletion of natural resources, deforestation and the destruction of ecosystems and loss of biodiversity.

Answer:

Globalization sure does come with a lot of consequences. Some of them are:

(1) Globalization restricts the growth of local industries (especially in the case of textiles & automobiles) as the imported goods are cheaper than the local goods.

(2) It causes poor work conditions for the workers as they have to work for longer periods of time with less wages.

(3) Globalization also affects the economy & the countries that export goods earn more or have MNCs in other places than countries that import goods.
