Correct Answer: B. 29%

Explanation

This question is designed to catch a) students who are not reading the question carefully, and b) students unsure of which nucleotides pair with which. The correct answer is 29%, because cytosine pairs with guanine in a 1:1 ratio. If you answered 21%, then you likely thought the question was more complex than it was.

Correct Answer: D. Istikharah

Correct Answer: D. the council was unrepresentative

Correct Answer: D. 7.47 x 10⁶Nm^-2

Explanation

To calculate the pressure of the ideal gas, we use the ideal gas law:

PV = nRT

Where:

P = pressure (what we want to find)

V = volume = 10⁻³ m³

n = number of moles = 3 mol

R = ideal gas constant = 8.314 J/(mol·K) (or sometimes approximated as 8.31 or 8.3 J/(mol·K))

T = temperature in Kelvin

First, convert the temperature from Celsius to Kelvin:

T(K) = T(°C) + 273.15

T(K) = 27 + 273.15 = 300.15 K

For simplicity and common practice in such problems, we often use 273:

T(K) = 27 + 273 = 300 K

Now, rearrange the ideal gas law to solve for P:

P = nRT / V

Let's use R = 8.314 J/(mol·K):

P = (3 mol * 8.314 J/(mol·K) * 300 K) / (10⁻³ m³)

P = (3 * 8.314 * 300) / 0.001 Nm⁻²

P = (24.942 * 300) / 0.001 Nm⁻²

P = 7482.6 / 0.001 Nm⁻²

P = 7482600 Nm⁻²

P = 7.4826 x 10⁶ Nm⁻²

Now let's compare this to the given options:

A. 2.49 x 10⁵ Nm⁻²

B. 7.47 x 10⁵ Nm⁻²

C. 2.49 x 10⁶ Nm⁻²

D. 7.47 x 10⁶ Nm⁻²

Our calculated value 7.4826 x 10⁶ Nm⁻² is closest to option D.

It's common for exam questions to use a slightly rounded value for R to get an exact match to an option. If we use R = 8.3 J/(mol·K):

P = (3 mol * 8.3 J/(mol·K) * 300 K) / (10⁻³ m³)

P = (3 * 8.3 * 300) / 0.001 Nm⁻²

P = (24.9 * 300) / 0.001 Nm⁻²

P = 7470 / 0.001 Nm⁻²

P = 7470000 Nm⁻²

P = 7.47 x 10⁶ Nm⁻²

Using R = 8.3 J/(mol·K) gives an exact match to option D. This suggests that R=8.3 J/(mol·K) was the intended value for the gas constant.

The final answer is 7.47 x 10^6 Nm^{-2}

Correct Answer: D. sharing of governmental powers.

Correct Answer: D. long gestation

Explanation

R-strategists are known for producing large numbers of offspring, though few live to maturity. This is a result of low parental investment, competition, etc. Despite such a large number of offspring, the gestation period for these species is generally shorter than that of K-strategists. For instance, the gestation period of mice is much shorter than the nine months seen in humans.

Correct Answer: C. state government

Correct Answer: D. Derisive

Correct Answer: D. debtors and creditors

Correct Answer: B. general price

Explanation

The value of any good is determined by its supply and demand and the supply and demand for other goods in the economy. A price for any good is the amount ofmoney it takes to get that good. the value is inherent in its purchasing power which is price
