At a recent football game you noticed that students tend to be near the same height as their parent of the same gender. You surveyed several students and their parents and recorded the data below.

$$\begin{matrix} \text{Student's Height (in.)} & \text{Parent's Height (in.)}\\ \text{61} & \text{56}\\ \text{62} & \text{57}\\ \text{63} & \text{62}\\ \text{65} & \text{66}\\ \text{65} & \text{60}\\ \text{66} & \text{66}\\ \text{67} & \text{68}\\ \text{68} & \text{63}\\ \text{68} & \text{69}\\ \text{70} & \text{71}\\ \text{72} & \text{68}\\ \text{71} & \text{73}\\ \text{73} & \text{67}\\ \text{74} & \text{71}\\ \end{matrix}$$

A galaxy is found to be $2.0 \times 10^6$ ly away from the Earth. Assume this galaxy does not have any motion relative to us other than that due to the expansion of space.

How does the nursing department at University Hospital represent how businesses frequently respond to deliberate organisational change? Are there any ways that the nature of the change—or the manner in which University Hospital is implementing it—differ from customary practises?

If one is attempting to determine the influence of genes or the environment on phenotypic variation, inbred strains with individuals of a relatively homogeneous or constant genetic background are often used. The variation observed between different inbred strains reared in a constant or homogeneous environment would likely be caused by genetic factors. What would be the source of variation observed among members of the same inbred strain reared under varying environmental conditions?

The midterm exam in a nursing course consists of 75 true/false questions. Imagine that an unprepared student makes random guesses for the answers.

b. Would it be unusual for a student to pass this exam by guessing and getting at least 45 correct answers? Why or why not?

Astronomers use cameras on Earth and in orbit to observe the solar system and other objects in space. Suppose that a camera on Earth takes a picture of an astronomical event. The picture shows an object that is large, dark, and has a bright area immediately around it. Which event does this picture most likely show? F. total solar eclipse G. total lunar eclipse H. waning gibbous moon I. waxing crescent moon

Earth’s gravitational field is 7.83 N/kg at the altitude of the space shuttle. At this altitude, what is the size of the force of attraction between a student with a mass of 45.0 kg and Earth?

Look at the drawings below of environmental problems and their solutions. Describe how each one affects the environment. Write two complete sentences for each. Follow the model. Modelo: Hay mucho humo que causa la contaminación del aire. Es un problema grave para el pueblo. _____

Radiation at 21 cm pours down on the Earth from outer space. Its origin is great clouds of hydrogen gas. Taking the background temperature of space to be 3.0 K, determine the ratio of the transition rates of stimulated emission to spontaneous emission and discuss the result

Shortly after arrival, C.B. becomes completely paralyzed and requires endotracheal intubation and mechanical ventilation. He is transferred to the neurologic intensive care unit for further support.
What are the overall goals of nursing care for C.B. at this time?

Read the passage below. Then, answer the questions.

DISCOVERING GALAXIES

Today, we know that Copernicus was right: the stars are very far from Earth. In fact, stars are so distant that a new unit of length-the lightyear-was created to measure their distance. A light-year is a unit of length equal to the distance that light travels through space in 1 year. Because the speed of light through space is about 300,000 $\mathrm{km} / \mathrm{s}$, light travels approximately $9.46$ trillion kilometers in one year.

Even after astronomers figured out that stars were far from Earth, the nature of the universe was hard to understand. Some astronomers thought that our galaxy, the Milky Way, included every object in space. In the early 1920's, Edwin Hubble made one of the most important discoveries in astronomy. He discovered that the Andromeda galaxy, which is the closest major galaxy to our own, was past the edge of the Milky Way. This fact confirmed the belief of many astronomers that the universe is larger than our galaxy.

Because the sun and Earth are close together, the distance between the sun and Earth is measured in light-minutes. A light-minute is the distance light travels in 1 minute. The sun is about 8 light-minutes from Earth. What is the approximate distance between the sun and Earth?

A. $2,400,000 \mathrm{~km}$

B. $18,000,000 \mathrm{~km}$

C. $144,000,000 \mathrm{~km}$

D. $1,000,000,000 \mathrm{~km}$
